Castleman's disease is a rare benign lymphoproliferative disorder that frequently affects lymph nodes of the mediastinal thorax and the neck. It very rarely affects the renal sinus. We report a case of Castleman's disease arising in the renal sinus in a 64-year-old man. The patient visited the hospital with the chief complaint of hematuria. Abdominal computed tomography revealed a homogeneous m...

BACKGROUND The Epstein-Barr virus (EBV) is responsible for the lymphoproliferative disorders observed in transplanted patients. METHODS The case history is described of a 59 year old man with a chorioretinal lesion who had received a single lung transplant and was on immunosuppressive treatment. Immunoglobulin gene rearrangement and EBV detection by polymerase chain reaction (PCR) with semiqu...

Patients with primary immunodeficiencies such as the Wiskott-Aldrich syndrome (WAS) are prone to develop Epstein-Barr virus (EBV) related lymphoproliferative disorders (LPDs). EBV LPD is most frequently seen in patients receiving immunosuppressive treatment after organ transplantation (post-transplant lymphoproliferative disorder), but can also arise in the primary immunodeficiencies. Typically...

introduction: castleman's disease is a rare lymphoproliferative disorder which may be confused with other causes of lymphadenopathy. case report: here we report a case of unicentric castleman's disease presenting with cervical lymphadenopathy. the patient was treated with complete surgical excision of lesion and was disease free at the time of reporting this article. this case has bee...

Pagetoid reticulosis (PR) is a low-grade primary cutaneous T-cell lymphoma that usually presents as a solitary, slowly enlarging erythematous or hyperkeratotic plaque on the distal areas of the extremities. Histopathologically, it is characterized by a dense, band-like infiltrate of atypical lymphocytes with prominent epidermotropism within a hyperplastic epidermis, and immunophenotypic studies...

castleman’s disease (angiofollicular lymphoid hyperplasia) includes a heterogeneous group of lymphoproliferative disorders. the cause of this disease remains uncertain. there are two types of localized castleman’s disease: the more common hyaline vascular and the plasma cell types. mixed variant is an uncommon localized lesion in general population. the lesions can occur in any part of the body...

CONTEXT Lymph node involvement in pancreatic cancer is a predictor of poor patient long-term survival. The detection of multiple metastatic peri-pancreatic nodes by EUS-FNA may dissuade the surgeon from undertaking a curative pancreatic resection. CASE REPORT We report an interesting case of a man with chronic lymphocytic leukemia, who presented with the diagnostic problem of a pancreatic sol...

Lymphoid hyperplasia of the tongue is a very rare benign lymphoproliferative lesion that closely resembles carcinoma or lymphoma, clinically or histopathologically. A case of benign lymphoid hyperplasia (BLH) of the tongue is reported. Clinically this lesion presented as a painless ulcer, which mimicked carcinoma of the tongue. Microscopy showed typical histologic features of multiple germinal ...

Tongue is formed of a mass of muscles and salivary gland embedded in anterior highly vascular and posterior lymphoid stroma and covered by specialized surface epithelium. Growths from all of these heterogonous components may occur resulting in a wide variation in clinical features and behavior, ranging from self-limiting to aggressive lesions. Therefore, surgical excision is the treatment of ch...

Human gammaherpesvirus infections are associated with development of lymphoproliferative disease. Understanding of the mechanisms of gammaherpesvirus lymphomagenesis during chronic infection in a natural host has been limited by the exquisite species specificity of human gammaherpesviruses and the expense of primates. Murine gammaherpesvirus gammaHV68 is genetically and biologically related to ...
