Transcriptome sequencing analysis of ursolic acid-mediated proliferation suppression on cutaneous T-cell lymphoma cells

Background:Ursolic acid is a triterpenoid compound found in natural plants that exhibits antiproliferative effects in various cancer cells.Our study is the first to demonstrate the strong inhibitory effects of ursolic acid on the proliferation of cutaneous T-cell lymphoma(CTCL)cells.We aimed to further investigate the underlying mechanism of the proliferation inhibition induced by ursolic acid in CTCL cells using transcriptome sequencing.Methods:Cell counting kit-8 assays were used to observe the effects of six traditional medicine monomers on the proliferation of CTCL cells.Transcriptome sequencing was used to identify differentially expressed genes after ursolic acid treatment.Bioinformatics analysis was performed to determine the potential mechanism.Real-time quantitative PCR and western blotting analyses were performed to confirm the sequencing results and verify the possible mechanisms of ursolic acid-mediated proliferation inhibition in CTCL cells.Results:Ursolic acid exhibited the strongest inhibitory effect on the proliferation of CTCL cells among the six traditional medicine monomers.Transcriptome sequencing analysis showed that 2,466 genes were significantly altered.Combined with Kyoto Encyclopedia of Genes and Genomes functional enrichment analysis and protein-protein interaction network analysis,the interaction of various pathways and signaling molecules,such as tumor necrosis factor-α,NLR family pyrin domain containing 1,c-Jun N-terminal kinase,and melanoma differentiation-associated gene 5,accounted for the anti-tumor effects of ursolic acid in CTCL cells.Conclusion:Ursolic acid significantly inhibited the proliferation of CTCL cells,and our study laid a theoretical foundation for the future treatment of CTCL using ursolic acid.

Epigenetics of cutaneous T-cell lymphoma:biomarkers and therapeutic potentials

Cutaneous T-cell lymphomas(CTCLs)are a heterogeneous group of skin-homing non-Hodgkin lymphomas.There are limited options for effective treatment of patients with advanced-stage CTCL,leading to a poor survival rate.Epigenetics plays a pivotal role in regulating gene expression without altering the DNA sequence.Epigenetic alterations are involved in virtually all key cancerassociated pathways and are fundamental to the genesis of cancer.In recent years,the epigenetic hallmarks of CTCL have been gradually elucidated and their potential values in the diagnosis,prognosis,and therapeutic intervention have been clarified.In this review,we summarize the current knowledge of the best-studied epigenetic modifications in CTCL,including DNA methylation,histone modifications,micro RNAs,and chromatin remodelers.These epigenetic regulators are essential in the development of CTCL and provide new insights into the clinical treatments of this refractory disease.

Low Dose Total Skin Electron Beam Radiation in Cutaneous T-Cell Lymphoma: Review

The treatment of advanced stage MF is especially challenging as single agent overall response rates are in the 35% range and chronic recurrence is the rule. The treatment of CTCL across all stages of disease is aimed at the goal of achieving and sustaining remission. Increasingly, low dose total skin electron beam therapy (TSEBT) is being utilized as a skin directed component in combination therapy for advanced stage CTCL. Researchers are seeking to better define the utility of low dose TSEBT as a method of debulking skin disease while simultaneously treating other disease compartments and in combination with sustained maintenance therapies of both the skin directed and systemic varieties. Data exists showing the efficacy of low dose TSEBT in early and advanced disease. There is also data documenting prolonged treatment responses with TSEBT plus adjuvant skin directed therapies such as PUVA and topical nitrogen mustard. Emerging data examining the role of low dose TSEBT in the prestem cell transplant preparation is also promising. This brief review summarizes the utility of low dose TSEBT in multiagent treatment regimens in CTCL.

Palliative Local Radiotherapy in the Treatment of Tumor-stage Cutaneous T-cell Lymphoma/ Mycosis Fungoides

Objective To determine the efficacy of palliative radiotherapy in treating tumor-stage cutaneous T-cell lymphoma/mycosis fungoides(MF).Methods From January 2008 to January 2013,a total of 11 patients with tumor-stage MF were treated with local radiation therapy in Peking Union Medical College Hospital.The median age of these patients was 53.36±14.45 years.Female-male ratio was 1:1.2.The average course of disease was 10.82±3.37 years.All the patients were treated with local electronic beam irradiation with a total median dosage of 48.55±9.51(40-74) Gy in an average of 24.55±5.57(20-40) fractions,5 fractions per week.Results The median follow-up time was 55.27±29.3(13-103) months.No severe acute or chronic side effects of irradiation were observed.Complete clinical response(CR) rate of the radiated sites was 54.5%(6/11),partial response(PR) rate was 36.4%(4/11),and the overall response rate(CR+PR) was 90.9%.One patient showed no response.Conclusion Local radiotherapy with psolaren plus ultraviolet A and/or interferon maintaining treatment is an effective palliative therapy in the treatment of tumor-stage MF patients.

Atypical Cutaneous Lymphoproliferative Disorder: A Fatal Mimic of Cutaneous T-Cell Lymphoma in a Patient with HIV Infection

Atypical cutaneous lymphoproliferative disorder (ACLD) is a rare condition that has been associated with HIV infection. Patients with ACLD present with diffuse, erythematous and pruritic skin lesions accompanied by generalized lymphadenopathy. The clinical characteristics of ACLD overlap most notably with several other conditions including Mycosis Fungoides/Sézary Syndrome (MF/SS), a cutaneous lymphoma of T-cell lineage. Unlike Mycosis Fungoides, the noxious infiltrates of ACLD are not monoclonal but polyclonal and consist of cytotoxic CD8+ T-cells instead of CD4+ T-cells or B-cells. Highly active antiretroviral therapy (HAART) has been reported to improve ACLD. We describe the case of a Caucasian man with longstanding HIV infection who presented with severe erythroderma. Skin and lymph node biopsies showed polyclonal CD8+ T-cell infiltrates. Gene rearrangement studies did not reveal an obvious clonal disorder. Hallmark peripheral blood findings consisting of a severe depletion of CD4+ T-lymphocytes and markedly elevated CD8+ cells provided an important diagnostic clue. Despite the purported benefits of HAART in ameliorating this disorder, erythroderma and extreme pruritus improved only after the patient began taking mycophenolate mofetil and hydroxyurea. Unfortunately, he succumbed to complications of methicillin-resistant Staphylococcus aureus septicemia. We alert readers to this rare HIV-associated condition which may mimic other benign and malignant skin conditions and briefly discuss diagnostic and therapeutic options.

Natural killer reprogramming in cutaneous T-cell lymphomas: Facts and hypotheses

To better understand the pathogenesis of Sézary cells, distinguish them from reactive skin-infiltrating T-cells and improve disease treatment, efforts have been made to identify molecular targets deregulated by the malignant process. From immunophenotypic analysis and subtractive differential expression experiments to pan-genomic studies, many approaches have been used to identify markers of the disease. During the last decade several natural killer(NK) cell markers have been found aberrantly expressed at the surface of Sézary cells. In particular, KIR3DL2/CD158 k, expressed by less than 2% of healthy individuals CD4+ T-cells, is an excellent marker to identify and follow the tumor burden in the blood of Sézary syndrome patients. It may also represent a valuable target for specific immunotherapy. Other products of the NK cluster on chromosome 19q13 have been detected on Sézary cells, raising the hypothesis of an NK reprogramming process associated with the malignant transformation that may induce survival functions.

Absence of enhancement in a lesion does not preclude primary central nervous system T-cell lymphoma:A case report

BACKGROUND Primary central nervous system lymphoma(PCNSL)is a non-Hodgkin lymphoma that originates in the central nervous system(CNS)and is exclusively limited to the CNS.Although most PCNSLs are diffuse large B-cell lymphomas,primary CNS T-cell lymphomas(PCNSTLs)are rare.PCNSTLs typically demonstrate some degree of enhancement on contrast-enhanced magnetic resonance imaging(MRI).To the best of our knowledge,non-enhancing PCNSTL has not been reported previously.CASE SUMMARY A 69-year-old male presented to the neurology department with complaints of mild cognitive impairment and gradual onset of left lower leg weakness over a span of two weeks.Initial MRI showed asymmetric T2-hyperintense lesions within the brain.No enhancement was observed on the contrast-enhanced T1 image.The initial diagnosis was neuro-Behçet’s disease.Despite high-dose steroid therapy,no alterations in the lesions were identified on initial MRI.The patient’s symptoms deteriorated further.An MRI performed one month after the initial scan revealed an increased lesion extent.Subsequently,brain biopsy confirmed the diagnosis of PCNSTL.The patient underwent definitive combined chemoradiotherapy.However,the patient developed bacteremia and died of septic shock approximately three months after diagnosis.CONCLUSION The absence of enhancement in the lesion did not rule out PCNSTL.A biopsy approach is advisable for pathological confirmation.

Plasmacytosis mimicking multiple myeloma in angioimmunoblastic T-cell lymphoma:A case report and review of literature

BACKGROUND Angioimmunoblastic T-cell lymphoma(AITL)is a common subtype of peripheral T-cell lymphoma.Approximately half of patients with AITL may concurrently present with hypergammaglobulinemia.Increased numbers of plasma cells in the bone marrow are commonly observed at diagnosis.These tumors mimic plasma cell myelomas,hindering a conundrum of clinical diagnoses and potentially delaying appropriate treatment.CASE SUMMARY A 78-year-old woman experienced poor appetite,weight loss of 5 kg,fatigue 2 months before presentation,and shortness of breath 2 d before presentation,but no fever or night sweats.Physical examination revealed splenomegaly and many palpable masses over the bilateral axillary regions,approximately>2 cm in size,with rubbery consistency and no tenderness.Blood tests revealed anemia and thrombocytopenia,lactate dehydrogenase level of 153 U/L,total protein level of 10.9 g/dL,albumin to globulin ratio of 0.2,and immunoglobulin G level more than the upper limit of 3000 mg/dL.The free kappa and lambda light chain concentrations were 451 and 614 mg/L,respectively.A pathological examination confirmed the diagnosis of AITL.The initial treatment was the cyclophosphamide,epirubicin,vincristine,and prednisolone regimen.Following this treatment,pleural effusion was controlled,and the patient was discharged in a stable condition and followed up in our outpatient department.CONCLUSION This report highlights the importance of differentiating reactive plasmacytosis from plasma cell myeloma in patients with hypergammaglobulinemia.A precise diagnosis of AITL requires a comprehensive evaluation,involving clinical,immunophenotypic,and histological findings conducted by a multidisciplinary team to ensure appropriate treatment.

Monomorphic epitheliotropic intestinal T-cell lymphoma with bone marrow involved: A case report

BACKGROUND Monomorphic epithelial intestinal T-cell lymphoma(MEITL)is a rare type of peripheral T-cell lymphoma.The clinical manifestations are diarrhea,abdominal pain,perforation and an abdominal mass.CASE SUMMARY We present a 52-year-old female patient who was diagnosed with MEITL.Further disease progression was observed after multiline chemotherapy.Eventually,the patient died of a severe infection.CONCLUSION MEITL is a rare intestinal primary T-cell lymphoma with aggressive behavior,a high risk of severe life-threatening complications,and a poor prognosis.

Sezary syndrome： a rare form of cutaneous T-cell lymphoma

Sezary syndrome （SS） is an erythrodermic, aggressive, cutaneous T-cell lymphoma （CTCL） characterized by a malignant T-cell clone that localizes in the blood and skin, and its diagnosis is based on clinical, histological and biological features. Here we describe a typical case of SS.

Primary cutaneous anaplastic large cell lymphoma with overexpressed Ki-67 transitioning into systemic anaplastic large cell lymphoma:A case report

BACKGROUND Primary cutaneous anaplastic large cell lymphoma(PC-ALCL)differs from systemic anaplastic large cell lymphoma(sALCL)in cell biological behavior,clinical features,treatment,and outcome.PC-ALCL has been reported to rarely transition into sALCL,but the underlying mechanism is not clear.Here we report such a case with certain characteristics that shed light on this.CASE SUMMARY Herein,we report a 43-year-old male with symptoms of a skin nodule and histologically confirmed PC-ALCL with high expression of Ki-67.After three months of observation,two skin nodules re-appeared with muscle layer involvement and was histologically confirmed as sALCL.Seventeen months after receiving six cycles of CHOP regimen,the patient had pain in the chest and back,cough,shortness of breath,and night sweats.This was confirmed as relapse of sALCL by immunohistochemistry and several organs,such as the lung were involved as shown by positron emission tomography/computed tomography.After four cycles of DICE plus chidamide regimens followed by auto-hematopoietic stem cell transplantation(ASCT),complete remission(CR)duration was achieved for twelve months while the patient was on maintenance with chidamide(20 mg)pills.CONCLUSION This case had significantly high expression of Ki-67 when diagnosed as PC-ALCL initially and then transitioned into sALCL,which is rare.Auto-ASCT combined with demethylation drugs effectively maintained CR and prolonged progression free survival.

T-CELL RECEPTOR GENE REARRANGEMENT ANALYSIS IN THE PRIMARY CUTANEOUS T-CELL LYMPHOMA

Object: The present paper is to evaluate the significance of T cell receptor (TCR) gene rearrange ments in primary cutaneous T cell lymphomas (PCTCL) as detected by analysis of Southern Blot (SBA) and polymerase chain reaction (PCR). Patients and Methods: Skin specimens and peripheral blood samples were taken from 44 patients with PCTCL, including 30 patients with mycosis fungoides (MF), 2 patients with Sezary's syndrome (SS), and 12 patients with PCTCL other than MF and SS (PNCTCL). 11 patients with a presumptive diagnosis of MF, 23 patients with lymphoproliferative dermatoses including lymphomatoid papulosis (LyP) and 8 patients with benign cutaneous lymphoid infiltrates were simultaneously studied by the amplification of junctional V (variable) J (joining) sequences of the rearranged TCRγ genes by PCR(TCRγPCR) and the analysis of TCRb chain genes by SBA(TCRβSBA) for detection of clonal gene rearrangements (GR). One lymph node specimen of a case with MF IIA was also detected by TCRγ PCR and TCRβSBA. Results: In MF, GR were detected by TCRγPCR and TCRβSBAb in 83.3 85.7% and 66.7% 71.4% of skin specimens of cases IIA IIB and in 57.1% 70.0% and 14.3% 10.0% of those of cases IA IB, respectively. GR were seen in 66.7% 71.4% and 33.3% 43.0.% of blood samples of cases IIA IIB, and 42.9% 40.0% and 0 10.0% of those of cases IA IB, respectively. GR was confirmed by TCRγ PCR and TCRβSBA in one lymph node showing dermato pathic lymphadenopathy of a case with MF IIA. In 11 patients of clinically suspected MF, GR were present in skin specimens of 5 cases (45.4%) and in blood samples of 3 cases ( 27.3% ) by TCRγ PCR. In PNCTCL, GR were found in 9 skin specimens (90.0%) from 10 patients detected by TCRγ PCR and in 6 skin specimens (75.0%) from 8 patients detected by TCRβSBA. GR were also seen in 6 blood samples (72.8%) from 11 patients detected by TCRγ PCR, and in 7 blood samples (70.0%) from 10 patients by TCRβSBA. In SS and LyP, GR were detected by TCRγ PCR and TCRβSBA in each of the two skin specimens of two cases with LyP and in each of the two blood samples of two cases with SS. GR were seen in one skin specimen of one case with SS and one blood sample of one case with LyP detected by TCRγPCR. Conclusions: This study demonstrated that TCRγ PCR is a rapid, more sensitive tool than TCRβSBA, can be used in the analysis of T cell clonality in skin, lymph node and blood samples of patients with PCTCL and indicated that this method forms a useful supplement to other methods for diagnosis of early and suspected MF, confirmation of PNCTCL and determination of extracutaneous involvement of lymph node and blood.

Subcutaneous panniculitis-like T-cell lymphoma invading central nervous system in long-term clinical remission with lenalidomide:A case report

BACKGROUND Subcutaneous panniculitis-like T-cell lymphoma(SPTCL)involvement in the central nervous system(CNS)is particularly rare.SPTCL with CNS involvement has an exceedingly poor prognosis,and no optimum therapeutic method has been discovered.To the best of our knowledge,this is the first reported case of SPTCL invading the CNS achieving long-term remission with lenalidomide maintenance therapy.CASE SUMMARY A 63-year-old man diagnosed with SPTCL was admitted to the hospital with severe headache for 15 d after four cycles of chemotherapy.Subsequent to the treatment,the patient developed CNS involvement.Craniotomy biopsy was pathologically diagnosed as CNS T-cell lymphoma,and two courses of chemotherapy were performed postoperatively.Due to the intolerance of the side effects of chemotherapeutic drugs,the patient received lenalidomide instead.The magnetic resonance imaging of the head at the 8 mo follow-up indicated no signs of recurrence,and the vital signs were stable.CONCLUSION Lenalidomide deserves further investigation as a targeted drug for SPTCL cases involving the CNS.

Chidamide combined with traditional chemotherapy for primary cutaneous aggressive epidermotropic CD8+cytotoxic T-cell lymphoma:A case report

BACKGROUND Traditional chemotherapy has benefited many patients with non-Hodgkin's lymphoma,but results in a very poor response in patients with rare lymphomas or refractory lymphomas.Previous studies have shown that chidamide has potential anti-lymphoma activity and reverses lymphoma cell chemoresistance to increase the chemosensitivity of lymphoma cells to traditional chemotherapy.CASE SUMMARY A 14-year-old boy was admitted to our hospital with a 5-d history of generalized erythema,papules,and blisters.Initially,the disease was refractory to potent antiallergic and anti-infective treatment,and his condition progressively worsened.Skin biopsy revealed primary cutaneous aggressive epidermotropic CD8+cytotoxic T-cell lymphoma.Considering that the disease is extremely rare in clinical practice,existing case reports have shown poor efficacy with traditional chemotherapy alone.We recommend chidamide combined with traditional chemotherapy for treatment.The regimen was as follows:Chidamide 30 mg/biw,cyclophosphamide 1100 mg/d1,pirarubicin 70 mg/d1,vincristine 2 mg/d1,dexamethasone 20 mg/d1-5,etoposide 100 mg/d1-5,in a 21 d cycle.The treatment effect was considerable,and complete remission was achieved after 4 cycles of treatment,after which the patient completed a total of 6 cycles of treatment.Subsequently,the patient regularly took chidamide 20 mg/biw as maintenance therapy for 1 year.To date,the patient has been disease-free for 3 years.CONCLUSION This case suggests that the combination of chidamide and traditional chemotherapy is effective in primary cutaneous aggressive epidermotropic CD8+cytotoxic T-cell lymphoma.

Two Cases of Tuberculosis Manifesting as Cutaneous Solitary Mass in Patients with Adult T-Cell Leukemia/Lymphoma

Tuberculosis (TB) is a major public health problem worldwide and a large number of fatal cases are still reported. Immunocompetent individuals are naturally susceptible to TB, and immunocompromised patients have a greater risk of infection. Although patients with adult T-cell leukemia/lymphoma (ATL) are in an immunosuppressed condition, there is only one reported case of TB accompanied with ATL in the English- language literature in the field of dermatology. Here, we report two patients with chronic-type ATL infected with TB manifesting as cutaneous solitary masses. Case 1 was a 58-year-old woman diagnosed with lumbar abscess with pulmonary TB. Case 2 was an 84-year-old woman diagnosed with tuberculous lymphadenitis in the left cervical region. It is important to raise the differential diagnosis of TB and perform tissue culture for acid-fast bacilli as well as Interferon-Gamma release assay test when dermatologists encounter mass lesions in patients with ATL.

2022 Chinese expert consensus and guidelines on clinical management of toxicity in anti-CD19 chimeric antigen receptor T-cell therapy for B-cell non-Hodgkin lymphoma

Adoptive cellular immunotherapy with chimeric antigen receptor(CAR)T cells has emerged as a novel modality for treating relapsed and/or refractory B-cell non-Hodgkin lymphoma(B-NHL).With increasing approval of CAR T-cell products and advances in CAR T cell therapy,CAR T cells are expected to be used in a growing number of cases.However,CAR T-cell-associated toxicities can be severe or even fatal,thus compromising the survival benefit from this therapy.Standardizing and studying the clinical management of these toxicities are imperative.In contrast to other hematological malignancies,such as acute lymphoblastic leukemia and multiple myeloma,anti-CD19 CAR T-cell-associated toxicities in B-NHL have several distinctive features,most notably local cytokine-release syndrome(CRS).However,previously published guidelines have provided few specific recommendations for the grading and management of toxicities associated with CAR T-cell treatment for B-NHL.Consequently,we developed this consensus for the prevention,recognition,and management of these toxicities,on the basis of published literature regarding the management of anti-CD19 CAR T-cell-associated toxicities and the clinical experience of multiple Chinese institutions.This consensus refines a grading system and classification of CRS in B-NHL and corresponding measures for CRS management,and delineates comprehensive principles and exploratory recommendations for managing anti-CD19 CAR T-cell-associated toxicities in addition to CRS.

T-lymphoblastic lymphoma with cutaneous involvement

To study dermatological manifestation of T-lymphoblastic lymphoma and to help clinicians in the diagnosis, we report here the case of a 75-year-old patient who presented with violaceous nodules acquired during the last 4 wk and affecting the scalp and right arm. The diagnosis of systemic lymphoma was suggested upon the appearance of cutaneous tumors, palpable lymph nodes and general symptoms including asthenia and weight-loss. The pathology features: positive immunostaining for CD3 and terminal deoxynucleotidyl transferase(Td T) and staging, led us to the final diagnosis of T-lymphoblastic lymphoma(T-LBL) with cutaneous involvement. He received a CHOP regimen as first-line treatment. Unfortunately, the patient relapsed and died 8 mo after the treatment initiation. T-LBL may be diagnosed by skin lesions. Additional immunostaining including Td T and experienced histopathologists are needed to correctly classify this aggressive disease and discuss the correct management including bone-marrow transplantation where appropriate.

Angioimmunoblastic T-cell lymphoma induced hemophagocytic lymphohistiocytosis and disseminated intravascular coagulopathy: A case report

BACKGROUND Angioimmunoblastic T-cell lymphoma(AITL) is a subtype of peripheral T-cell lymphoma, with heterogenous clinical manifestations and poor prognosis. Here,we report a case of AITL induced hemophagocytic lymphohistiocytosis(HLH)and disseminated intravascular coagulopathy(DIC).CASE SUMMARY An 83-year-old man presented with fever and purpura of both lower limbs for one month. Groin lymph node puncture and flow cytometry indicated a diagnosis of AITL. Bone marrow examination and other laboratory related indexes indicated DIC and HLH. The patient rapidly succumbed to gastrointestinal bleeding and septic shock.CONCLUSION This is the first reported case of AITL induced HLH and DIC. AITL is more aggressive in older adults. In addition to male gender, mediastinal lymphadenopathy, anaemia, and sustained high level of neutrophil-to-lymphocyte ratio may indicate a greater risk of death. Early diagnosis, early detection of severe complications, and prompt and effective treatment are vital.

Intestinal natural killer/T-cell lymphoma presenting as a pancreatic head space-occupying lesion:A case report

BACKGROUND Intestinal natural killer/T-cell lymphoma(NKTCL)is a rare and aggressive non-Hodgkin’s lymphoma,and its occurrence is closely related to Epstein-Barr virus infection.In addition,the clinical symptoms of NKTCL are not obvious,and the specific pathogenesis is still uncertain.While NKTCL may occur in any segment of the intestinal tract,its distinct location in the periampullary region,which leads clinicians to consider mimics of a pancreatic head mass,should also be addressed.Therefore,there remain huge challenges in the diagnosis and treatment of intestinal NKTCL.CASE SUMMARY In this case,we introduce a male who presented to the clinic with edema of both lower limbs,accompanied by diarrhea,and abdominal pain.Endoscopic ultrasound(EUS)showed well-defined homogeneous hypoechoic lesions with abundant blood flow signals and compression signs in the head of the pancreas.Under the guidance of EUS-fine needle biopsy(FNB)with 19 gauge or 22 gauge needles,combined with multicolor flow cytometry immunophenotyping(MFCI)helped us diagnose NKTCL.During treatments,the patient was prescribed the steroid(dexamethasone),methotrexate,ifosfamide,L-asparaginase,and etoposide chemotherapy regimen.Unfortunately,he died of leukopenia and severe septic shock in a local hospital.CONCLUSION Clinicians should enhance their understanding of NKTCL.Some key factors,including EUS characteristics,the right choice of FNB needle,and combination with MFCI,are crucial for improving the diagnostic rate and reducing the misdiagnosis rate.

Rothmund-thomson syndrome and cutan T-cell lymphoma in childhood

We report a 3-year-old girl suffering from RothmundThomson Syndrome (RTS). The patient at birth had multiplex anomalies: poikilodermatous rash, sceletal abnormalities: palatoschisis, micrognathi, aplasia radii, hypoplastic right and left thenar and thumbs, pesequinus on both site, ectopy renis. The patient in the later ages was detected dental malformation, facial dysmorfism. At the age 3, she had lasion in her muscle. After biopsy, histological examination showed cutan T-cell lymphoma. The patient is the first case who had cutan T-cell lymphoma associated with RTS in this young age.
