Abstract

A case of testicular embryonal carcinoma developed in s cryptorchid testis is presented with a review of the literature. According to Campbell's series, the incidence of malignant cryptorchid testis was 11.6%. and his statistical evaluation was similar to Gilbert and Hamilton's series of 7,000 cases of testicular neoplasms where 840 tumors were developed in undescended testes(12%). Both authors agree that the chance of neoplastic development in a cryptorchid testis is approximately 48 times greater then that developing in a normally descended testis. Several cases of testicular tumor were reported sporadically in Korea, but malignant tumors in cryptorchism were rarely seen in the literatures Only two cases of malignant cryptorchid testis were already reported in Korea.
