Abstract
Non-Hodgkin’s Lymphoma (NHL) of the testis is an uncommon extranodal presentation accounting for 1% of all NHL, 2% of extranodal lymphoma, and 5% of all testicular tumours. There are various subtypes of primary Non-hodgkins lymphoma of testis including diffuse large B-cell lymphoma (DLBCL), Burkitt’s lymphoma, follicular lymphoma and B-cell lymphoma. Differential diagnosis of testicular lymphoma is made with seminoma of classic or spermatocytic type, embryonal carcinoma, viral and granulomatous orchitis. Orchidectomy with adjunctive chemotherapy or radiotherapy is the treatment. It is important to identify primary testicular DLBCL correctly and distinguish it from other entities because of differences in therapy, management, and prognosis. We hereby present a case of a 76 year old man who presented with bilateral testicular enlargement with dragging pain and abdominal discomfort since 1 month. FNAC was done followed by right sided orchidectomy and was sent for histopathological study. Immunohistochemistry was done which showed LCA and CD 20 positivity and negative for CD 3. A final diagnosis of diffuse large B-cell lymphoma was made.
