Carcinoma in situ of testicular tissue adjacent to malignant germ-cell tumors: A study of 105 cases

Abstract

Examination of histologic specimens from 105 patients with malignant germ-cell tumors of the testis confirms a high incidence of carcinoma in situ in seminiferous tubules adjacent to the tumors. The assumption that carcinoma in situ may be the origin of germ-cell tumors is supported.
