[Metastatic tumor of spermatic cord with elevation of serum human chorionic gonadotropin beta-subunit].
A 62-year-old man was presented with a firm mass in right scrotum. Serum LDH and AFP were within normal range, but hCG-beta was elevated (2.3 ng/ml). Under the diagnosis of right testicular tumor, he underwent right radical orchiectomy. The specimen was a spermatic cord tumor with poorly differentiated adenocarcinoma. hCG-beta was still elevated postoperatively and gastric fiber revealed adenocarcinoma of the stomach. Histochemical staining for hCG-beta was positive in both tumor of the spermatic cord and stomach. Finally the tumor was diagnosed as metastatic tumor of spermatic cord from gastric cancer, causing the elevation of hCG-beta.
