title: [Secondary non-Hodgkin lymphoma of the prostate: a case report].
abstract: A 72-year-old man presenting with difficulty of urination, was diagnosed with benign prostatic hyperplasia and transurethral resection of prostate (TUR-P) was performed. However, pathological diagnosis of 40% of the TUR-specimen was of malignant lymphoma. Immunohistochemical examination revealed B-cell origin, diffuse and medium-cell type, according to the LSG classification. Then we performed chemotherapy with a combination of cyclophosphamide, adriamycin, vincristine and prednisolone. Trans-rectal biopsy specimens of the prostate after 3 courses of chemotherapy, revealed no cells of malignant lymphoma.
