[Malignant lymphoma of the penis: report of two cases]

We report two cases of malignant lymphoma of the penis. A 64-year-old man presented with painful indurations of the penis. A computerized tomography (CT) scan showed a swollen retroperitoneal lymph node 5 cm in diameter. Penectomy confirmed the diagnosis of B cell malignant lymphoma, diffuse large type. Despite systemic chemotherapy with a CHOP regimen, he died of disease 7 months postoperatively. The second case was in a 63-year-old man presenting with multiple nodules in the penis and scrotum. Biopsy of a scrotal nodule revealed B cell malignant lymphoma, diffuse medium size type. A CT scan demonstrated widespread lesions (stage III E). He has been in complete remission for 10 months following, multidisciplinary treatments. We reviewed 21 cases of malignant lymphoma of the penis which have been reported in the literature.
