THREE CASES OF SECONDARY TESTICULAR TUMORS

Abstract

Three cases of secondary testicular tumors were reported and their metastatic routes were discussed.
Case 1. A 19-year-old man was first admitted in June, 1966 because of a left testicular tumor. Two years prior to the admission, he had multiple neoplasmas on his head and face and four months later, exploratory laparotomy was performed because of suspicious obstructive jaundice and metastatic pancreatic tumor but no radicality. Histological findings of multiple neoplasmas and pancreatic tumor revealed neuroblastoma. Intensive chemotherapy and irradiation were without effect. Left testicular tumor was first noted in December, 1967 and began to be growing. Left orchiectomy was performed on 16, January 1968. Histological findings showed also neuroblastoma. It was thought that this testicular tumor was metastasised from another tumor site via blood vessels.
Case 2. A 80-year-old man first found a painless mass on the abdomen near the left of penil radix in March, 1968. Several months later, left inguinal lymphonodes, the left spermatic cord and the scrotal contents became swollen. An induration in the root of penis was found at that time. Penile amputation and resection of left inguinal mass including the scrotal contents were performed on December 9, 1968. Histological findings showed that sarcomatous cells were found in the subcutaneous tissue, which invaded the inguinal lymphonodes and in the left testis also. It was thought that the testicular tumors were metastasised from the inguinal tumor via testicular arteries or veins. However, other metastatic routes such as lymphatic vessels could not be ruled out.
Case 3. A 65-year-old man was admitted for urinary retention on Feb. 15, 1968. Physical examination revealed an enlarged and hard prostate. Laboratory examination showed a high value of serum acidphosphatase. Histological findings of needle biopsy showed adenocarcinoma. For the purpose of hormone treatment, castration was performed and metastases in the left testis were found by microscopic examination. The metastatic routes may be hematogenic or lymphatic.
