Primary reticulum cell sarcoma of testis in a 12-year-old

A 12-year-old boy with primary reticulum cell sarcoma of the testis who is alive and free of tumor 32 months after orchiectomy, radiation therapy to inguinal, iliac and retroperitoneal lymph nodes and chemotherapy is reported. Seven previously documented cases of childhood primary testicular lymphoma are reviewed. The patient with reticulum cell and one with lymphosarcoma were alive and tumor-free 4 and 18 months respectively. The other 5 with primary testicular lymphosarcoma died. Four survived for periods up to 1 year, 3 developing generalized lymphosarcoma and 1 leukemia. The fifth was tumor-free for 4 years and developed leukemia 2 weeks before death. The small number of cases precludes evaluation of survival in relation to various modes of therapy. Primary lymphoma of testis, no evidence of lymphoma elsewhere at time of orchiectomy, does exist. Its relatively benign biologic behavior in some remains an enigma.
