Multicentric Castleman's disease (MCD) of plasma cell type is a reactive lymphoproliferative disease. While 67Ga scanning is useful in the detection of malignant lymphomas, its role in reactive lymphadenopathy is unknown. We report the absence of 67Ga uptake in three patients with MCD of plasma cell type and present a review of the English literature on this condition.

Abstract Background Focal lesions of the kidney comprise a spectrum entities that can be broadly classified as malignant tumors, benign and non-neoplastic lesions. Malignant tumors include renal cell carcinoma subtypes, urothelial carcinoma, lymphoma, post-transplant lymphoproliferative disease, metastases to kidney, rare Benign angiomyolipoma (fat-rich fat-poor) oncocytoma. Non-neoplastic infe...

PURPOSE The incidence and clinical and imaging criteria of different pathological forms of lacrimal fossa lesions in the Delta region of Egypt were studied. METHODS A retrospective study of patients with lacrimal fossa lesions for the past 10 years was conducted. A total of 146 cases were identified. Their medical records were reviewed for clinical and imaging data (computed tomography scan, ...

the histopathologic diagnosis of orbital and ocular adnexal lymphoproliferative lesions is difficult, resulting controversy in classification, determining benignity or malignancy of them and treatment modality selection. we designed the following study to evaluate clinical, histopathologic and if necessary immunochemical features of them in decreasing indeterminate cases. the study includes 51 ...

Infectious mononucleosis (IM) is Epstein-Barr virus-associated and self-limited lymphoproliferative disorder. The histopathologic features of the nasopharynx in IM are rarely described. In this report, we described a patient of IM with atypical T-cell proliferation in the nasopharynx. In-situ hybridization for EBV-encoded RNA with immunostaining against CD20 was used for evaluation of EBV infec...

Primary immunodeficiencies (PID) are genetically determined irreversible disorders of structure and/or functions the immune system's cellular and humoral components, accompanied by frequent infectious diseases contributing to development malignant neoplasms. Lymphomas most oncological disease in PID patients: non-Hodgkin's lymphomas occur 60 % neoplasms cases, Hodgkin lymphoma - 20 %, leukemias...

Posttransplant lymphoproliferative disorder (PTLD) is a spectrum of diseases that involves abnormal lymphoid and/or plasmacytic proliferation in patients with solid organ or hematopoietic cell transplantation. It is a condition with a low incidence of 3.5-4.3% in liver transplant (LT) recipients. This case involves a 63-year-old male with history of LT for chronic HCV induced cirrhosis who pres...

Pulmonary mucosa-associated lymphoid tissue-derived (MALT) lymphoma is a rare disease. This disorder is considered to be a model of antigen-driven lymphoma, which is driven either by autoantigens or by chronic inflammatory conditions. Low-grade B-cell MALT lymphoma may develop from a nonneoplastic pulmonary lymphoproliferative disorder, such as lymphocytic interstitial pneumonitis (LIP). A rece...
