Its most frequent side effects have been listed as peripheral neuropathy, neuropathic pain, thrombocytopenia, and gastrointestinal problems. Allergic skin reaction is a rarely documented side effect in patients receiving bortezomib-based chemotherapy. A combination therapy consisting of intravenous bortezomib, oral Revlimid tablets, and oral dexamethasone tablets has been prescribed for the patient after his recent diagnosis of plasma cell leukemia. While receiving his third treatment cycle, he developed an allergic reaction (skin rash) involving the neck, and wrists, and mild bilateral eye swelling. The infusion was stopped immediately and then ciprofloxacin ophthalmic solution and oral diphenhydramine 25 mg were prescribed to the patient with significant improvement in his clinical condition. He was temporarily taken off bortezomib. At a follow-up visit a week later, a significant improvement was noticed in his condition. Rash had reduced on neck and wrists, and eye swelling had reduced as well. As of the time of writing this case report, he has been temporarily taken off bortezomib, but other medications in the treatment regimen were continued as prescribed.展开更多

Cytogenetic and molecular abnormalities lead to resistance to treatment and transformation to plasma cell leukemia, which is defined by the presence in circulating blood of plasma cells over 2 G/L, or more than 20% of leukocytes. It is an uncommon hematological malignancy with a poor prognosis. Against this backdrop, we report an observation of multiple myeloma transformed into plasma cell leukemia diagnosed at the Hôpital Principal de Dakar (HPD) that occurred on a 64-year-old man with a history of thyroidectomy followed for multiple myeloma presenting with Salmon et Durie stage IIIA and ISS stage I. Despite a marked improvement in management strategy, myeloma remains an almost invariably incurable disease. However, the development of genetic and molecular biomarkers is necessary to improve its prognosis.展开更多

Methods: The prospective, observational and descriptive study was carried out at the Ngaliema Clinic in Kinshasa from July 2016 to December 2019. The variables studied were the plasma cell types and the prognosis groups according to GOASGUEN and ZANDECKI. The nucleolus, the chromatin and the N/C ratio of 2 for each plasma cell encountered in multiple myeloma are examined in order by asking three successive questions as follows: 1) Is the nucleolus present? If yes, we denote 1;if not, note 0;2) Is the chromatin thin? If yes, we score 1;if not we score 0;3) The N/C ratio is greater than 6, if so, 1 is noted;if not, we note 0. We obtain a number with 3 successive digits preceded by the letter P for each plasma cell. Results: The overall rate of immature plasma cells and aberrant plasma cells in MM among Congolese was high at 26.6%. Their integration in the prognostic formulas showed for group A" = 22 patients, group B" = 5 patients and group C" = 32 patients. Examination of plasma cell types in the deceased showed that 14/17 had a P001 plasma cell count ≥ 15%. Conclusion: The high rate of aberrant and/or immature plasma cells, the P001 plasma cell type at a rate ≥ 15%, found mostly in group C" with poor prognosis, are responsible for the aggressive nature of MM in Congolese Blacks.展开更多

We report a case of a 38-year-old man who presented with worsening left eye pain, proptosis, tearing, gritty sensation, blurred vision and multiple lymphadenopathy. An axillary lymph node resection showed reactive follicular and interfollicular lymph node hyperplasia, and increased eosinophils and plasma cells(at least 80% of Ig G+ plasma cells were positive for IgG 4). A distinct feature was the presence of multifocal, perifollicular histiocytic granulomas, which formed a wreath around the entire follicles. The human herpes virus 8 was not detected by immunohistochemistry. In addition, an extensive panel of special stains, immunohistochemistry, and flow cytometry was negative for lymphoma, fungal, or mycobacterial infection. The findings were suggestive of IgG 4-related sclerosing disease-associated lymphadenopathy. Further laboratory testing showed a significant increase of serum immunoglobulin E(> 23000 IU/mL) and slight increase of total Ig G, but normal serum Ig G4. Even though perifollicular granuloma is a nonspecific histopathologic feature and can be seen in other diseases, such as nodular lymphocyte predominant Hodgkin lymphoma, Ig G4-related lymphadenopathy should be listed in the differential diagnoses of benign reactive lymph nodes, especially when perifollicular granuloma and plasmacytosis coexist.展开更多

At admission, the patient was free of pain. Physical examination showed enlarged and palpable bilateral submandibular masses, but no palpable mass or organomegaly in the abdomen. Laboratory findings were as follows: total protein 90 g/L with γ-globulin of 37.3% (33 g/L), total bilirubin 4 mg/L, aspartate aminotransferase 39 IU/L, alanine aminotransferase 67 IU/L,γ-glutamyl transpeptidase 1 647 IU/L, and amylase 135 IU/L. Autoantibodies were negative, and tumor markers were within the normal range. Serum IgG4 level was markedly elevated (18 900 rag/L). Computed tomography (CT) showed diffuse swelling of the pancreas and dilatation of both common and intra-hepatic bile ducts. Endoscopic retrograde pancreatography (ERP) revealed diffuse irregular and narrow main pancreatic duct and stenosis of the lower common bile duct. Biopsy specimens from the pancreas, salivary gland and liver showed marked periductal IgG4-positive plasma cell infiltration with fibrosis. We considered this patient to be autoimmune pancreatitis (AIP) with fibrosclerosis of the salivary gland and biliary tract, prescribed prednisolone at an initial dose of 40 mg/d. Three months later, the laboratory data improved almost to normal. Abdominal CT reflected prominent improvement in the pancreatic lesion. Swelling of the salivary gland also improved. At present, the patient is on 10 mg/d of prednisolone without recurrence of the pancreatitis. We present here a case of AIP with fibrosclerosis of salivary gland and biliary tract.展开更多

The discharges of the ICP cells were shown to be independent of each other. Furthermore, the total plasma density at simultaneous multi-cell discharge was observed to be approximately equal to the summation of the plasma density when the cells discharge separately. Based on the linear summation phenomenon, it was shown that a larger area plasma with a uniform density and temperature profile could be constructed with multi-collisional ICP cells.展开更多

Occasionally, central giant cell granuloma-like lesions may be seen in association with hyperparathyroidism. Rarely, PGCG-like lesions have been described in a background of hyperparathyroidism. We describe the case of a 91-year-old woman taking teriparatide for the treatment of osteoporosis and presented with a peripheral giant cell granuloma of the mandibular posterior area.展开更多

Radi...A 25-year-old woman presented a unilateral mandibular swelling, after laboratory analysis, radiological studies and aspiration puncture biopsy, the pathological diagnosis of Central Giant Cell Granuloma was made. Radiographically, the multilocular lesion involved the left lower first molar and was 30 mm long by 20 mm high. Dental extraction of the molar involved with forceps and exeresis in toto of the tumor were performed using a Volkmann cutting curette. The tumor made up of 90% vascular tissue produced intra-surgical bleeding that made visibility difficult. The bone bed curettage was aggressive except for its base in direct contact with the inferior dental nerve. Subsequently, to avoid recurrence, the surgical protocol includes a double irrigation with Carnoy’s solution, (fixative composed of 60% ethanol, 30% chloroform and 10% glacial acetic acid 98%) for 5 minutes that produces chemical cauterization. Finally, it was washed with physiological solution and the cavity was filled with iodoformed gauze. The gauze was exchanged and removed gradually over three weeks for second intention healing. This case is presented to demonstrate that inexpensive chemical treatment can be safely used for outpatient surgery under local anesthesia. Because Carnoy’s solution achieved control of intraoperative bleeding, allowed bone healing and prevented recurrence of the lesion in clinical radiographic follow-up for 15 years.展开更多

During first complete remission after routine chemotherapy, the patient received autologous blood stem cell transplantation, but he had relapse later. He gained a second CR after chemotherapy and underwent hi-HSCT from his daughter, who had HLA mismatched at three loci. Recovery of hemopoiesis was found at day 14 and complete donor chimerism was confirmed by PCR-STR on day 34, 95 and 238. The patients have survived disease-free for 56 months since hi-HSCT, without serious graft-versus-host-disease.展开更多

Its etiopathogenesis is unclear; however it is suggested that it can arise as a reactive response to trauma. This report describes an aggressive variety of CGCG which raises a question; can extraction of tooth modify the behavior of CGCG? A 46 years old male had reported with a rapidly increasing intraoral and extraoral swelling of lower jaw following tooth extraction. Radiographic examination revealed a large multilocular lesion involving the body and ramus of mandible which had been proved to be aggressive CGCG on histopathological examination. The importance of radiographic examination prior to extraction of teeth and importance of inclusion of CGCG in jaw swellings associated with mobility of teeth or failure of healing sockets is emphasized.展开更多

Comparing with the 57 cases of multiple myeloma (MM) treated in our hospital, the following features were observed in PPCL: (1) The age was younger, with a mean of 45.2 years, 34.1% of the patients were under 40 years. (2) Onset was abrupt. Duration from onset to diagnosis was 2 months or less in 77% patients but never beyond 6 months. (3) 81.8% patients had liver enlargement, 59.1% splenomegaly and 61.4% sternum tenderness. (4) All patients showed marked anemia with an average hemoglobin of 65 g/L. BPC count was less than 100 × 109/L in 76% patients and WBC was more than 10×109/L in 77%. (5) Plasma cell number in the marrow was markedly increased with an average of 69%, of which the blast cells and immature forms were predominant. (6) No destruction of bones was shown on X-ray film in 68.3% patients. (7) The response to chemotherapy was poor with a total response rate of 18% and a mean survival of 2 months. All the above-mentioned clinical features were significantly different from those of MM. In addition, these two diseases were also different in cytology, cytogenetics and ultrastructure. Therefore, PPCL should be considered as a special type of acute leukemia distinct from MM. High dose of alkylating agents in combination with autologous bone marrow transplantation might improve the prognoses.展开更多

It is defined by a blood plasmacytosis greater than 2 G/l or a plasma cell level greater than 20% of leukocytes. It can be primitive or secondary to multiple myeloma (MM). We reported 3 cases of PL. Observations: Case 1: A 59 years old woman with fever, anemia with 7 g/dl, hyperleukocytosis 9200/mm<sup>3</sup>, thrombopenia 86 G/l inflammatory biological syndrome with CRP at 129 mg/l, hypercalcemia at 120 mg/l, renal failure with serum creatinine at 35 mg/l, urea at 0.85 g/l and 24-hour proteinuria at 0.98 g/24h. Β2 microglobulin at 10.34 mg/l. The blood smear shows dysmorphic plasma cells at 68% and the bone marrow at 79% of dysmorphic plasma cells. The immunophenotyping of blood cells, the electrophoretic serum protein, shows PL CD38+, secondary of a MM LAMBDA. Case 2: A 65-year-old man with type 2 diabetes presented, right femoral neck, anemia, hyperleukocytosis at 22 G/l, and thrombocytopenia at 99 G/l. There was no hypercalcemia, or kidney failure. The blood smear showed 28% of plasma cells and 9% of blasts. On the myelogram, the marrow was normal richness with significant medullary plasmacytosis (31%) made up of dysmorphic plasma cells. The CT scan showed a settling of the body of D5 with heterogeneous osteocondensation. The patient was transferred to hematology where she was treated with polychemotherapy. The evolution was unfavorable following a death due to malignant hypercalcemia. Case 3: A 62-year-old woman who had a 5-year follow-up of Ig G kappa multiple myeloma was treated with Melphalan, Prednisone, and thalidomide with a therapeutic break for 2 months. She came back to the Internal Medicine department with: severe global dehydration, anemia with externalized bleeding gingivorrhagia, pain in mechanical bones of the ribs, lower limbs, and pelvis, bilateral pneumonia. The biology found hyperleukocytosis at 99 G/l, anemia at 4.7 g/dl, thrombocytopenia at 31 g/l, hypercalcemia at 190 mg/l, renal failure with creatinine at 34 mg/L, and urea at 1.08 g/l, a biological inflammatory syndrome with CRP 294 mg/l. The smeared blood had shown 93% blood plasma cells and immunophenotyping showed CD38+. The patient died before specific treatment for the disease. Conclusion: Plasma cell leukemia is a rare atypical variant, complicating essentially multiple light chain myeloma. She must be suspected especially when there are cytological abnormalities such as major leukocytosis or thrombocytopenia, which are unusual in classical myeloma. Evolution is usually a very bad prognosis, with a median survival of 12 to 14 months for the form primary and 2 to 3 months for the secondary form.展开更多

文摘Perifollicular granuloma is a unique histologic feature and whether it is associated with immunoglobulin G4(IgG 4)-related disease is controversial. We report a case of a 38-year-old man who presented with worsening left eye pain, proptosis, tearing, gritty sensation, blurred vision and multiple lymphadenopathy. An axillary lymph node resection showed reactive follicular and interfollicular lymph node hyperplasia, and increased eosinophils and plasma cells(at least 80% of Ig G+ plasma cells were positive for IgG 4). A distinct feature was the presence of multifocal, perifollicular histiocytic granulomas, which formed a wreath around the entire follicles. The human herpes virus 8 was not detected by immunohistochemistry. In addition, an extensive panel of special stains, immunohistochemistry, and flow cytometry was negative for lymphoma, fungal, or mycobacterial infection. The findings were suggestive of IgG 4-related sclerosing disease-associated lymphadenopathy. Further laboratory testing showed a significant increase of serum immunoglobulin E(> 23000 IU/mL) and slight increase of total Ig G, but normal serum Ig G4. Even though perifollicular granuloma is a nonspecific histopathologic feature and can be seen in other diseases, such as nodular lymphocyte predominant Hodgkin lymphoma, Ig G4-related lymphadenopathy should be listed in the differential diagnoses of benign reactive lymph nodes, especially when perifollicular granuloma and plasmacytosis coexist.
文摘A 62-year-old male was referred to our hospital because of liver dysfunction, diffuse pancreatic swelling, and trachelophyma. At admission, the patient was free of pain. Physical examination showed enlarged and palpable bilateral submandibular masses, but no palpable mass or organomegaly in the abdomen. Laboratory findings were as follows: total protein 90 g/L with γ-globulin of 37.3% (33 g/L), total bilirubin 4 mg/L, aspartate aminotransferase 39 IU/L, alanine aminotransferase 67 IU/L,γ-glutamyl transpeptidase 1 647 IU/L, and amylase 135 IU/L. Autoantibodies were negative, and tumor markers were within the normal range. Serum IgG4 level was markedly elevated (18 900 rag/L). Computed tomography (CT) showed diffuse swelling of the pancreas and dilatation of both common and intra-hepatic bile ducts. Endoscopic retrograde pancreatography (ERP) revealed diffuse irregular and narrow main pancreatic duct and stenosis of the lower common bile duct. Biopsy specimens from the pancreas, salivary gland and liver showed marked periductal IgG4-positive plasma cell infiltration with fibrosis. We considered this patient to be autoimmune pancreatitis (AIP) with fibrosclerosis of the salivary gland and biliary tract, prescribed prednisolone at an initial dose of 40 mg/d. Three months later, the laboratory data improved almost to normal. Abdominal CT reflected prominent improvement in the pancreatic lesion. Swelling of the salivary gland also improved. At present, the patient is on 10 mg/d of prednisolone without recurrence of the pancreatitis. We present here a case of AIP with fibrosclerosis of salivary gland and biliary tract.
文摘BACKGROUND No qualitative or quantitative analysis of contrast-enhanced computed tomography(CT)images has been reported for the differentiation between ameloblastomas and central giant cell granulomas(CGCGs).AIM To describe differentiating multidetector CT(MDCT)features in CGCGs and ameloblastomas and to compare differences in enhancement of these lesions qualitatively and using histogram analysis.METHODS MDCT of CGCGs and ameloblastomas was retrospectively reviewed to evaluate qualitative imaging descriptors.Histogram analysis was used to compare the extent of enhancement of the soft tissue.Fisher’s exact tests and Mann–Whitney U test were used for statistical analysis(P<0.05).RESULTS Twelve CGCGs and 33 ameloblastomas were reviewed.Ameloblastomas had a predilection for the posterior mandible with none of the CGCGs involving the angle.CGCGs were multilocular(58.3%),with a mixed lytic sclerotic appearance(75%).Soft tissue component was present in 91%of CGCGs,which showed hyperenhancement(compared to surrounding muscles)in 50%of cases,while the remaining showed isoenhancement.Matrix mineralization was present in 83.3%of cases.Ameloblastomas presented as a unilocular(66.7%),lytic(60.6%)masses with solid components present in 81.8%of cases.However,the solid component showed isoenhancement in 63%.No matrix mineralization was present in 69.7%of cases.Quantitatively,the enhancement of soft tissue in CGCG was significantly higher than in ameloblastoma on histogram analysis(P<0.05),with a minimum enhancement of>49.05 HU in the tumour providing 100%sensitivity and 85%specificity in identifying a CGCG.CONCLUSION A multilocular,lytic sclerotic lesion with significant hyperenhancement in soft tissue,which spares the angle of the mandible and has matrix mineralization,should indicate prospective diagnosis of CGCG.
文摘BACKGROUND Conventional therapies for primary plasma cell leukemia(pPCL)are usually ineffective,with a short remission time with the use of multiple myeloma medications,showing aggressiveness of pPCL.B-cell lymphoma-2 inhibitor venetoclax is usually used for relapsed/refractory multiple myeloma(RRMM)with t(11;14).There are very few studies published on the use of venetoclax in pPCL without t(11;14).Similarly,histone deacetylase inhibitors are considered effective for the treatment of RRMM,but there are no reports on their use in pPCL.CASE SUMMARY A 57-year-old woman with severe anemia,thrombocytopenia,multiple bone destruction,impaired renal function,and 42.7%of peripheral plasma cells is reported.After multiple chemotherapy regimens and chimeric antigen receptor Tcell treatment,the disease progressed again.The patient had very good partial response and was maintained for a long time on venetoclax in combination with chidamide and dexamethasone therapy.CONCLUSION The success of venetoclax-chidamide-dexamethasone combination therapy in achieving a very good partial response suggested that it can be used for refractory/relapsed pPCL patients who have been exhausted with the use of various drug combinations and had poor survival outcomes.

文摘The plasma density and electron temperature of a multi-source plasma system composed of several collisional inductively coupled plasma (ICP) cells were measured by a doubleprobe. The discharges of the ICP cells were shown to be independent of each other. Furthermore, the total plasma density at simultaneous multi-cell discharge was observed to be approximately equal to the summation of the plasma density when the cells discharge separately. Based on the linear summation phenomenon, it was shown that a larger area plasma with a uniform density and temperature profile could be constructed with multi-collisional ICP cells.
文摘Peripheral giant cell granuloma (PGCG) is a common reactive gingival lesion that histologically resembles the central giant cell granuloma, and is a central lesion of the jaws. Occasionally, central giant cell granuloma-like lesions may be seen in association with hyperparathyroidism. Rarely, PGCG-like lesions have been described in a background of hyperparathyroidism. We describe the case of a 91-year-old woman taking teriparatide for the treatment of osteoporosis and presented with a peripheral giant cell granuloma of the mandibular posterior area.
文摘A 25-year-old woman presented a unilateral mandibular swelling, after laboratory analysis, radiological studies and aspiration puncture biopsy, the pathological diagnosis of Central Giant Cell Granuloma was made. Radiographically, the multilocular lesion involved the left lower first molar and was 30 mm long by 20 mm high. Dental extraction of the molar involved with forceps and exeresis in toto of the tumor were performed using a Volkmann cutting curette. The tumor made up of 90% vascular tissue produced intra-surgical bleeding that made visibility difficult. The bone bed curettage was aggressive except for its base in direct contact with the inferior dental nerve. Subsequently, to avoid recurrence, the surgical protocol includes a double irrigation with Carnoy’s solution, (fixative composed of 60% ethanol, 30% chloroform and 10% glacial acetic acid 98%) for 5 minutes that produces chemical cauterization. Finally, it was washed with physiological solution and the cavity was filled with iodoformed gauze. The gauze was exchanged and removed gradually over three weeks for second intention healing. This case is presented to demonstrate that inexpensive chemical treatment can be safely used for outpatient surgery under local anesthesia. Because Carnoy’s solution achieved control of intraoperative bleeding, allowed bone healing and prevented recurrence of the lesion in clinical radiographic follow-up for 15 years.
文摘Here we report a successful protocol in treatment of a patient with primary plasma cell leukemia (PPCL) using haploidentical stem cell transplantation (hi-HSCT). During first complete remission after routine chemotherapy, the patient received autologous blood stem cell transplantation, but he had relapse later. He gained a second CR after chemotherapy and underwent hi-HSCT from his daughter, who had HLA mismatched at three loci. Recovery of hemopoiesis was found at day 14 and complete donor chimerism was confirmed by PCR-STR on day 34, 95 and 238. The patients have survived disease-free for 56 months since hi-HSCT, without serious graft-versus-host-disease.
文摘Central giant cell granuloma(CGCG) is found exclusivelyin jaws. Its etiopathogenesis is unclear; however it is suggested that it can arise as a reactive response to trauma. This report describes an aggressive variety of CGCG which raises a question; can extraction of tooth modify the behavior of CGCG? A 46 years old male had reported with a rapidly increasing intraoral and extraoral swelling of lower jaw following tooth extraction. Radiographic examination revealed a large multilocular lesion involving the body and ramus of mandible which had been proved to be aggressive CGCG on histopathological examination. The importance of radiographic examination prior to extraction of teeth and importance of inclusion of CGCG in jaw swellings associated with mobility of teeth or failure of healing sockets is emphasized.
文摘Four cases of primary plasma cell leukemia (PPCL) admitted to Zhongshan Hospital from 1959 to 1987 are reported with a review on additional 40 cases reported in China. Comparing with the 57 cases of multiple myeloma (MM) treated in our hospital, the following features were observed in PPCL: (1) The age was younger, with a mean of 45.2 years, 34.1% of the patients were under 40 years. (2) Onset was abrupt. Duration from onset to diagnosis was 2 months or less in 77% patients but never beyond 6 months. (3) 81.8% patients had liver enlargement, 59.1% splenomegaly and 61.4% sternum tenderness. (4) All patients showed marked anemia with an average hemoglobin of 65 g/L. BPC count was less than 100 × 109/L in 76% patients and WBC was more than 10×109/L in 77%. (5) Plasma cell number in the marrow was markedly increased with an average of 69%, of which the blast cells and immature forms were predominant. (6) No destruction of bones was shown on X-ray film in 68.3% patients. (7) The response to chemotherapy was poor with a total response rate of 18% and a mean survival of 2 months. All the above-mentioned clinical features were significantly different from those of MM. In addition, these two diseases were also different in cytology, cytogenetics and ultrastructure. Therefore, PPCL should be considered as a special type of acute leukemia distinct from MM. High dose of alkylating agents in combination with autologous bone marrow transplantation might improve the prognoses.
文摘BACKGROUND Chronic myeloid leukemia(CML)is a clonal hematopoietic stem cell disorder.Plasma cell dyscrasias are a rare heterogeneous group of hematological disorders.The co-occurrence of CML and plasma cell dyscrasias in the same patient is an extremely rare incident and has been reported in several cases in the literature.CASE SUMMARY In the present report,we described a rare case of the co-occurrence of CML and plasma cell dyscrasias in a 48-year-old man,and we discussed the reason why monoclonal gammopathy of undetermined significance progressed to smoldering multiple myeloma and eventually to multiple myeloma while being treated with dasatinib for CML.The tyrosine kinase inhibitor treatment and cytogenetic change may contribute to this phenomenon,and clonal hematopoiesis of indeterminate potential may lead to both CML and multiple myeloma cells in a patient.Future studies are warranted to further explain the hidden reasons.CONCLUSION This case highlights that gene translocation may contribute to initiation and sustainability of clonal proliferation.Moreover,the treatment with tyrosine kinase inhibitor and cytogenetic change may contribute to progression from monoclonal gammopathy of undetermined significance to smoldering multiple myeloma and eventually to multiple myeloma.
文摘<span style="font-family:Verdana;">Plasma cell leukemia is a rare malignant hemopathy, characterized by a peripheral plasma cell proliferation of more than 20% of the leukocyte formula. A few rare cases have been described. From which we report a case of plasma cell leukemia in a 52-year-old Nigerien subject initially in a coma, whose anemia led to the diagnosis in the Onco-Hematology department of the National Hospital of Niamey and the evolution was marked by clinical and biological remission after 3 cures of CTD, but died in an infectious picture after 6 cures.
文摘Introduction: Plasma cell leukemia (PL) is a rare lymphoproliferative disorder characterized by the monoclonal proliferation of plasma cells in the marrow and blood peripheral. It is defined by a blood plasmacytosis greater than 2 G/l or a plasma cell level greater than 20% of leukocytes. It can be primitive or secondary to multiple myeloma (MM). We reported 3 cases of PL. Observations: Case 1: A 59 years old woman with fever, anemia with 7 g/dl, hyperleukocytosis 9200/mm<sup>3</sup>, thrombopenia 86 G/l inflammatory biological syndrome with CRP at 129 mg/l, hypercalcemia at 120 mg/l, renal failure with serum creatinine at 35 mg/l, urea at 0.85 g/l and 24-hour proteinuria at 0.98 g/24h. Β2 microglobulin at 10.34 mg/l. The blood smear shows dysmorphic plasma cells at 68% and the bone marrow at 79% of dysmorphic plasma cells. The immunophenotyping of blood cells, the electrophoretic serum protein, shows PL CD38+, secondary of a MM LAMBDA. Case 2: A 65-year-old man with type 2 diabetes presented, right femoral neck, anemia, hyperleukocytosis at 22 G/l, and thrombocytopenia at 99 G/l. There was no hypercalcemia, or kidney failure. The blood smear showed 28% of plasma cells and 9% of blasts. On the myelogram, the marrow was normal richness with significant medullary plasmacytosis (31%) made up of dysmorphic plasma cells. The CT scan showed a settling of the body of D5 with heterogeneous osteocondensation. The patient was transferred to hematology where she was treated with polychemotherapy. The evolution was unfavorable following a death due to malignant hypercalcemia. Case 3: A 62-year-old woman who had a 5-year follow-up of Ig G kappa multiple myeloma was treated with Melphalan, Prednisone, and thalidomide with a therapeutic break for 2 months. She came back to the Internal Medicine department with: severe global dehydration, anemia with externalized bleeding gingivorrhagia, pain in mechanical bones of the ribs, lower limbs, and pelvis, bilateral pneumonia. The biology found hyperleukocytosis at 99 G/l, anemia at 4.7 g/dl, thrombocytopenia at 31 g/l, hypercalcemia at 190 mg/l, renal failure with creatinine at 34 mg/L, and urea at 1.08 g/l, a biological inflammatory syndrome with CRP 294 mg/l. The smeared blood had shown 93% blood plasma cells and immunophenotyping showed CD38+. The patient died before specific treatment for the disease. Conclusion: Plasma cell leukemia is a rare atypical variant, complicating essentially multiple light chain myeloma. She must be suspected especially when there are cytological abnormalities such as major leukocytosis or thrombocytopenia, which are unusual in classical myeloma. Evolution is usually a very bad prognosis, with a median survival of 12 to 14 months for the form primary and 2 to 3 months for the secondary form.
文摘Castleman disease,also known as angiofollicular lymph node hyperplasia,is a rare lymphoproliferative disease with a poorly understood etiology.We herein report a 27-year-old male with a six months history of painless and gradually enlarged lymph nodes presented recurrent cough and expectoration with fever and chills for ten days.The patient was recurrent fever even received empiric anti-inflammatory therapy.Then the right cervical follicles biopsy and pathological examination revealed Castleman disease Plasma cell variant.Castleman disease is a rare disorder that is hard to diagnose early.Now,we will review this case,summarize Castleman disease and propose a feasible diagnostic protocol.
