Primary testicular lymphoma with rupture: An unusual presentation.

Primary testicular lymphoma usually presents as a unilateral testicular mass with occasional bilateral involvement. The tumor show contiguous spread to rete testis, epididymis spermatic cord and rarely to tunica albuginea. We report a case of primary testicular lymphoma which showed rupture of tunica albuginea with involvement of inguinal lymph node which is unusual. A 50-year-old male patient presented with right inguinal swelling and right side scrotal swelling of five months' duration. Fine needle aspiration of the right inguinal lymph node was done and was suggestive for lymphoma/seminoma. Histopathology of right orchiectomy revealed non-Hodgkin's lymphoma (NHL). Further investigations did not reveal any other organs involved with non-Hodgkin's lymphoma. Primary testicular lymphoma usually shows spread to extranodal sites like skin, central nervous system and Waldeyer's ring at presentation and at relapse. Whereas, less common sites are lung, bone, liver, gastrointestinal system and nodal sites, especially the paraaortic lymph nodes. Testicular lymphoma with involvement of the inguinal lymph node is unusual. Clinical presentation of such cases may mimic germ cell tumors.
