title: [Giant seminoma in abdominal retention of the testis manifested with unilateral leg pain: a case report].
abstract: A 26-year-old man was admitted to the department of surgery of our hospital with a complaint of intermittent left leg pain for the past two weeks. Ultrasonography revealed reduced blood flow to the tibial artery, which suggested a vascular disease like arteriosclerosis obliterans. Enhanced computed tomography (CT) revealed a huge abdominal tumor and a 3-dimensional CT scan showed a feeding artery from the left renal artery to the huge tumor. Findings of routine blood and urine examinations were elevated levels of lactate dehydrogenase, alkaline phosphatase, and C-reactive protein. Surgical exploration revealed a giant tumor with clouded ascites in the abdominal cavity containing class V cells revealed by cytological examination. The tumor was easily resected. Its vascular pedicle was thick and hypertrophied. Thus, it could be traced to the origin of left gonadal artery. At this time, the surgeon incidentally noticed the absence of left testis in the patient's scrotum. The resected specimen was 25 x 18 x 12 cm in size, and it weighed 3000 gm. The histological finding was pure seminoma invaded to peritoneum. His leg pain was relieved after the tumor resection.
