Rosai Dorfman Testis: A Rare Case Report

Rosai dorfman disease was defined by Rosai and Dorfman as an idiopathic histiocytic proliferative disorder afflicting nodes in the year 1969. The disease presents in the 10-20 year age group mainly as fever, painless lymphadenopathy, and hypergammaglobulinaemia, however older ages can also be affected. Although it is mainly a node involving disease, 25% extranodal cases have been reported worldwide. The eyes and ocular adnexa, head and neck region upper respiratory tract, skin and subcutaneous tissue, and central nervous system are the commonly involved extranodal sites. We present a case of extranodal testicular Rosai Dorfman in a 40 year old male with right testicular lump which radiologically mimicked a malignancy but on histopathology was diagnosed to be a benign Testicular Rosai Dorfman.
