A Rare Case of Primary Cutaneous Diffuse Large B- Cell Lymphoma- Leg Type with Testicular Infiltration in a Young Male

Primary cutaneous B-cell lymphomas (PCBCLs) are a heterogenous group of rare clonal B-cell lymphoproliferative disorders with distinct clinicopathological features compared with nodal counterparts. It is less frequent than lymphomas of T-cells. Primary cutaneous diffuse large B-cell lymphoma-leg type (PCLBCL-LT) is a rare subtype which constitutes only 4%. It is predominantly seen in elderly people and has a female preponderance. We report a case of PCLBCL-LT with testicular infiltration occurring in a young male who presented with three painless skin swellings over thigh, chest and upper lip and with bilateral scrotal swelling.
