A 42-year-old male presented with bilateral scrotal swelling and sense of abdominal fullness. Ultrasonography and computed tomographic (CT) scan showed right testicular tumor, left scrotal hydrocele and excessive ascites, but no distant metastases. The serum lactic acid dehydrogenase (LDH) value was as high as 4,060 IU/L and beta human chorionic gonadotropin (hCG) value was 4.0 ng/ml while alpha fetoprotein (AFP) value was within the normal range. Right high orchiectomy was performed as well as the ascites and the left scrotal fluid sampling. Histological examinations revealed anaplastic seminoma in the right testis, and similar cells were found in the ascites and the left scrotal fluid. The patient received three courses of BEP chemotherapy consisting of bleomycin, VP-16 and cisplatin. The ascites and tumor markers (LDH and beta hCG) decreased markedly. Intraperitoneal dissemination of the tumor cells seems to be caused by invasion along the right spermatic cord, but the route of dissemination into the left hydrocele fluid is not known. To the best of our knowledge, this is the first case report of testicular tumor that showed intraperitoneal dissemination without any evidence of metastasis to the lymph nodes or distant organs.
