Abstract

Giant lymph node hyperplasia (Castleman's disease) is a rare disease, which represents a peculiar form of lymph node hyperplasia. Generally, it has been considered as benign and localized disease but recently, revealed malignant transformation in some cases of multicentric form. It usually occurs on the mediastinum and occasionally neck, lung, axilla, mesentery, broad ligament, retroperitoneum or soft tissue of extremities. Histopathologically, it is divided into hyaline vascular or plasma cell type and the former is characterized with prominent vascular proliferation and hyalinization in the central portion and tight concentric layering of lymphocytes at the periphery of the follicles (mantle zone) and the latter is characterized by a diffuse plasma cell proliferation in the interfollicular area. From the point of view of clinical presentation, it has been divided into solitary form, which presents as a localized mass located most commonly in the mediastinum, and multicentric form, which occurs multiple location and has systemic manifestation and transformation into malignancy. Herein we report a case of Giant lymph node hyperplasia occurring in the left spermatic cord in a 58-year old male with brief review of literatures.
