The current cumulative number of reported cases is minimal. We report a case of a 44-year-old woman with a hard mass in the pelvic retroperitoneal that has been gradually increasing in size for many years. Abdominopelvic MRI scan showed a left retroperitoneal mass and visible calcifications. The patient underwent resection of the left retroperitoneal mass and the pathological diagnosis was Castleman disease of hyaline vascular type.展开更多

METHODS:During routine physical examination,a mass was detected in the left abdomen of a 53-year-old man with no signs or symptoms.The patient underwent ultrasoundguided aspiration biopsy and operative excision after laboratory examination,ultrasonography,and CT. RESULTS:Ultrasonography demonstrated a dominant hypoechogenic mass with hypervascularity in the retroperitoneum.CT detected a relatively homogenous enhanced lesion and several satellite nodules.After the mass and several lymph nodes were resected, histopathologic examination demonstrated a lymphocytepredominant infiltrate surrounding the germinal centres and extensive capillary proliferation,consistent with the hyaline-vascular type of Castleman’s disease.The patient received postoperative chemotherapy and remained free of recurrence 3 months later. CONCLUSION:Ultrasonography and contrast-enhanced CT can provide a positive differential diagnosis of hyalinevascular Castleman’s disease which is a kind of giant lymph node hyperplasia with hypervascularity.展开更多

The recently introduced, endoscopic ultrasonography （EUS）-guided trucut biopsy （TCB） is a useful diagnostic rnodality for obtaining tissue samples from peripancreatic lesions. However, its role in diagnosing CD remains unknown. We report a case of localized, peripancreatic, hyaline-vascular CD biopsied using EUS. The pathology results were initially interpreted as an extranodal, marginal-zone B-cell lyrnphoma. However, polyrnerase chain reaction （PCR） study for the IgH gene rearrangement revealed a polyclonal pattern. We also reviewed the relevant literature. To our knowledge, this is the first illustrated report on EUS-TCB findings of CD with its pathology results of EUS-TCB mimicked a B-cell lymphoma.展开更多

METHODS Clinical features and related information on diagnosis and treatment of 14 cases of CD were retrospectively analyzed and the literature reviewed. RESULTS Based on the clinical classification, localized CD was found in 8 of the 14 cases. Both the results of lymph node biopsy and histopathology indicated they were a hyaline-vascular type. The multicentric type CD was detected in 6 cases, among which 4 were plasma cell type and 2 mixed type based on histopathologic examination. There were a variety of clinical situa-tions in the 14 cases, with a lack of specificity. They were previously misdiag-nosed as other diseases, and final diagnosis depended on a histopathologic examination. The 8 patients with localized CD underwent excision, without recurrence up to now. The 6 patients with multicentric-type CD were treated with glucocorticoids or combined chemotherapy, and all achieved remission. CONCLUSIONS CD has complicated clinical manifestations and is difficult to diagnose. Lymph node biopsy is important for early diagnosis. An optimal curative effect can be achieved with a suitable therapeutic option, based on histopathology and clinical classification.展开更多

Histologically, it can be classified as hyaline vascular type, plasma cell type, or mixed type. Clinically two different subtypes of the CD are present: Unicentric and multicentric. Unicentric CD is generally asymptomatic and associated with hyaline vascular type, and its diagnoses depend on the localized lymphadenopathy on examination or imaging studies. However, multicentric CD presents with generalized lymphadenopathy and systemic symptoms including malaise, fever, night sweats, weight loss, and it is associated with the plasma cell type and mix type. Herein, we report a patient with unicentric CD of the plasma cell type without systemic symptoms, who developed end stage renal failure caused by amyloidosis 6 years after onset of CD.展开更多

A rare case of cervical CD diagnosed at lymph node dissection for esophageal carcinoma is reported. An esophageal tumor was identified in a 67-year-old man during a follow-up examination after surgery for oral carcinoma. Esophagoscopy revealed a type 1 tumor in the cervical esophagus. Histology of esophagoscopic biopsies indicated squamous cell carcinoma. Contrastenhanced computed tomography revealed swollen lymph nodes of the right cervical region. No distant metastasis was detected. Esophageal carcinoma, T2N2M0, Stage ⅢA was diagnosed. Neoadjuvant chemotherapy was recommended, but the patient rejected the chemotherapy. The patient underwent laparoscopic-assisted transhiatal esophagectomy. The histopathological diagnosis was moderately differentiated squamous cell carcinoma with pT1bN0M0, Stage ⅠA. On histology, the swollen lymph nodes of the right cervical region revealed CD. The patient's postoperative course was relatively good.展开更多

Castleman’s Disease is a very rare medical disease and the presence of this condition in the pleura is even rarer and there are only few reported cases. The presence of symptoms is also unusual and has been mostly described in multicentric cases of castleman’s disease instead of solitary lesions (unicentric castleman). We report a case of unicentric pleural castlema’s disease with presence of constitutional symptoms. Methods. A 36-year-old male without any significant past medical history who presented to the emergency due to an incidental large pleural effusion seen in chest radiograph, but referring chronic constitutional symptoms consistent of significant weight loss and chronic cough. Results. Chest computed tomography revealed a mass and several attemps with minimally invase approach failed to identify the lesion. The mass was excised through VATS but due to its significant vascularity, it had to be converted to open thoracotomy. Conclusion. The treatment of unicentric lesions is mainly complete surgical excision and the prognosis is excellent with some chances of recurrence. There are less than one dozen of reported pleural castleman reported in the literature. This case evidence than unicentric lesion may exhibit constitutional symptoms and confirmed than lesions above 5 cm can be removed by VATS but the chances for conversion to an open thoracotomy are high.展开更多

A 36-year-old male without any significant past medical history who presented to the emergency due to an incidental large pleural effusion seen in chest radiograph, but referring chronic constitutional symptoms consistent of significant weight loss and chronic cough. Results. Chest computed tomography revealed a mass and several attemps with minimally invase approach failed to identify the lesion. The mass was excised through VATS but due to its significant vascularity, it had to be converted to open thoracotomy. Conclusion. The treatment of unicentric lesions is mainly complete surgical excision and the prognosis is excellent with some chances of recurrence. There are less than one dozen of reported pleural castleman reported in the literature. This case evidence than unicentric lesion may exhibit constitutional symptoms and confirmed than lesions above 5 cm can be removed by VATS but the chances for conversion to an open thoracotomy are high.
文摘Unicentric Castleman’s disease (UCD) is localized lymphoproliferative disease and has favourable prognosis. Surgery offers complete cure of unicentric Castleman disease. Radiotherapy offers either complete response or variable clinical response and cure in selected patients. The present case report is of a young unmarried obese girl presented with pain in right iliac fossa for 2 months. On pelvic ultrasound and MRI performed for diagnosis only single enlarged right external iliac lymph node was the positive finding. The CT scan guided biopsy was performed and the histopathological finding was lymphoid lesion-reactive lymphoid hyperplasia is favoured over Hodgkin’s lymphoma. Successful laparoscopic complete excisional surgery was performed for this single enlarged external iliac lymph node. The final histopathological report of the lymph node removed was unicentric Castleman’s disease, hyaline vascular type. This is the 16th such reported case of pelvic re</span><span>troperitoneal UCD of hyaline vascular type treated by surgical excision, and 3rd case treated by Laparoscopic excisional surgery. By now at the time of reporting this case 4 months of follow up has been completed and patient does not have any symptom nor not show any sign of residual disease locally on transabdominal ultrasound examination and whole-body PET CT scan is</span><span> also normal.
