TUMORS OF THE EPIDIDYMIS, SPERMATIC CORD AND TESTICULAR TUNICS

Abstract

Tumors of the testicle are relatively rare, constituting 5.8 per thousand (0.58 per cent.) of all malignant tumors in men (census statistics on the mortality of cancer in the registration area of the U. S.¹). Nevertheless, they have received a great deal of attention in the literature, both in this country and abroad, and are still a subject for controversy from the clinical as well as the pathologic standpoint. The conclusion has gradually evolved that for practical purposes all tumors of the testicle are malignant (Ewing) and that tumors, either benign or malignant, arising in the adjacent structure (epididymis, cord and tunics) are so rare as scarcely to deserve mention. The occurrence in our experience during the last four years of one case of pure fibroma of the cord and two very unusual epithelial neoplasms of the epididymis has prompted us to make a rather exhaustive survey of the
