胃癌を原発とする転移性副睾丸腫瘍および精索腫瘍の各1例

Abstract

Two cases of rare metastatic tumor from gastric cancer, one to the epididymis another to spermatic cord, were presented. The literatures were briefly reviewed to collect the secondary tumor of the epididymis and spermatic cord; and metastatic route, incidence, histological picture were discussed. Case 1; A 50-year-old male was admitted to the hospital with complaint of a painless enlargement of the left scrotal contents of 3 months duration. Extirpation of the epididymis and the spermatic cord was performed. Histopathological diagnosis was made as metastatic adenocarcinoma of the spermatic cord. X-ray examination of the gastrointestinal tract revealed evidence of tumor of hen egg size in the lesser curvature of the stomach, and it was verified by laparotomy. Along the gastro-hepatic and the gastro-colic ligaments, a number of the metastatic tumors varying in size from rice corn to little finger's tip were found. There were gross evidence of metastases to the gallbladder, peritoneum, greater omentum and mesentery. Schnitzler's metastasis was also present in the pelvis. Case 2; A 59-year-old male had had gastrectomy for gastric cancer in 1966 at the 1st surgical department of Yamaguchi University. There was no gross evidence of metastasis to the liver or other abdominal organs at that time. Histopathological diagnosis was made as adenocarcinoma. Postoperative course was uneventful until he was admitted to the hospital with complaint of a painless enlargement of the right scrotal contents of 2 weeks duration in November 1967. Right epididymectomy was performed and metastatic adenocarcinoma of the epididymis was confirmed histologically.
