Abstract
We reviewed cases of intrascrotal tumors treated at our institution except for germ cell testicular tumors. From 1977 to 1998 (22 years), 120 cases of intrascrotal tumors treated at the University of Tsukuba. Of these, 15 cases (12.5%) were not germ cell testicular tumors. The patients' ages varied between 2 and 77 years with a mean of 49.6. The most common complaint regarding symptoms was painless testicular enlargement. Tumor weight ranged from 2 to 200 g, with an average of 104.6 g. The histological diagnoses of 15 patients were 8 malignant lymphomas, 2 paratesticular rhabdomyosarcomas, 2 metastatic tumors (origin; stomach and prostate), 1 epidermoid cyst, 1 cyst of tunica testis, and 1 adenomatoid tumor. As for the cases with malignant lymphoma, all of them were non-Hodgkin's lymphoma whose clinical stages were stage I in 2 cases and stage IV in 6 cases. Five 8 patients died in spite of systemic chemotherapy after an orchiectomy, whereas 2 cases with metastatic tumors died of primary cancer, and two cases with paratesticular rhabdomyosarcoma are still alive and have had no evidence of disease. Intrascrotal tumors except for germ cell testicular tumors are not common, and consist of various diseases. In particular, some kinds of malignant lymphoma mimic anaplastic seminoma histopathologically. Therefore, accurate diagnosis and precise treatment is important in the patient with intrascrotal tumors.
