A Rare Case of Primary Diffuse Large Cell Non Hodgkin's Lymphoma of Testis.

ABSTRACT

Primary testicular lymphomas (PTL) are rare entities representing 1-2% of Non-Hodgkin's Lymphoma (NHL) and 1-7% of malignant testicular tumours. They are most commonly seen in men older than 60 years. The most common type of primary testicular lymphoma (PTL) is diffuse large B-cell type which has the potential for aggressive clinical behaviour. We report the case of a 45 years old male with primary testicular lymphoma which was first diagnosed on Fine Needle Aspiration Cytology (FNAC) and subsequently confirmed histopathologically and immunophenotypically as Diffuse Large B-Cell Lymphoma (DLBCL) showing CD20 positivity. This case report confirms the literature data concerning the rarity of testicular Non Hodgkin's Lymphoma (TNHL) with DLBCL being the most common phenotype and the poor prognosis of the disease despite aggressive management.
