Three cases of secondary testicu]ar tumors were reported and their metastatic routes were discussec]. Case l. A 19-year-old man was first admitted in June, 1966 because of a left testicu]ar 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 testicu]ar tumor was first noted in December, 1967 and began to be growing. Left orchieclomy 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, Ieft inguinal lymphonodes, the left spermatic cord and the scrotal contents became swo]len. An induration in the root of penis was found at lhat 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 sub-cutaneous tissue, which invaded the inguinal lymphonodes and in the left testis also. It was thought that the testicu]ar tumors were metastasised from the inguinal tumor via testicular arteries or veins. However, other metasta.tic 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 ex-amination 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.
