Two cases of testicular malignant lymphoma

Abstract

Two cases of non-Hodgkin’s lymphoma of the testis are reported. The ages of the two patients were 78 and 74 years old. One patient has hydrocele of the testis and fine needle aspiration cytology was performed; initially, seminoma was suspected. High orchiectomy was performed in each patient, and microscopic findings of specimens revealed diffuse large B cell lymphoma in both patients, and one patient was positive for CD5. In addition, the two patients were classified as having the nongerminal center B cell type and were placed in the poor-prognosis group. Chemotherapy and radiotherapy are important because testicular malignant lymphoma often results in recurrence and metastasis, and postoperatively, our patients were subjected to R-CHOP therapy and follow-up. It was considered that fine needle aspiration cytology for hydrocele of the testis should be performed in elderly patients to distinguish it from seminoma.
