Testicular Lymphoma: A Rare Entity

Testicular malignancy in old age men should be thoroughly studied because of low rate of incidence. Incidence of testicular lymphomas have been shown to be nearly 9% among all testicular malignancies and 1-2% of all lymphomas found in human body. The most common hisopathological pattern among lymphomas is B-cell type and of these diffuse large B-cell subtype is commonest; however, less commonly, Burkitt's lymphoma, anaplastic lymphoma or Hodgkin's lymphoma may primarily involve the testis. Testicular lymphoma is rare whether as a primary or as a secondary origin. Diffuse Large B-Cell Lymphomas (DLBCL) is the most common histopathological type if primary in origin; however aggressive patterns like, Burkitt's lymphoma, are more common when there is secondary involvement of testis. Stage of the lymphoma (Ann Arbor staging) determines the prognosis of the disease. Other prognostic factors include presence of B symptoms and International Prognostic Index (IPI) score, involvement of spermatic cord and other testis. Immunohistochemistry should be done after histopathological diagnosis for effective treatment of variants of testicular lymphoma. High inguinal orchiectomy along with chemotherapy with or without radiotherapy is current treatment of choice for these tumours. In this article, the case of testicular lymphoma is presented in a 61-year-old male patient, clinical presentation, investigations and surgical and chemotherapeutic management with discussion with respect to previous clinical studies. In this case report, patient presented with swelling of left scrotum for which he underwent the radiological and biochemical investigations. He was further planned for frozen section biopsy. The histopathological and immunohistochemical analysis was suggestive of DLBCL, as final diagnosis.
