Primary penile malignant lymphoma: report of a rare case

A 73-year-old male presented with a 3-month history of two penile masses: one on the shaft and one on the glans penis. Both lesions were poorly defined, fixated and without tenderness. The sizes were 1.0 × 1.0 × 1.0 cm and 1.2 × 1.5 × 1.5 cm, respectively. The patient underwent lumpectomy of the glans penis; we confirmed malignant lymphoma of the glans penis (B-cell derived; diffused large B-cell) by postoperative pathological examinations. CHOP (cyclophosphamide-hydroxydaunorubicin-oncovin-prednisone) chemotherapy was administered. The patient was tumour-free at the 33-month follow-up.
