Pathological Anatomy and Histology 

 of the Testicle 



DAVID M. DAVIS 



BALTIMORE 



The classification of lesions of the testicle herein adopted, while not 

 perfect or complete, is at least comprehensive and affords a reasonable 

 structure upon which to build the conceptions of testicular pathology. It 

 is taken largely from the classification of Sebileau and Descomps. 

 The interpretation of tumors and other lesions of the testicle is made 

 difficult by the uncertainty which still exists concerning the origin of the 

 elements of this organ. 



Some have questioned the propriety of considering it as a gland, since 

 its secretion consists of formed elements, or its distinctive cells as 

 epithelium, for the same reason. This distinction is, however, academic, 

 and need not interfere in the consideration of the pathological anatomy 

 of the organ. The same may be said of the question whether the intersti- 

 tial cells are of mesothelial or epithelial origin.

 Anomalies of Development 



Hermaphroditism and Pseudohermaphroditism. True Jiermaphrodir 

 tism is an exceedingly rare condition. Most of the examples of it have 

 been found in the lower animals. It may be bilateral, unilateral, or 

 lateral. In the bilateral form, there are ovaries and testes on both sides ; 

 in the unilateral form, ovary and testis on one side, with a single gonad on 

 the other ; and in the lateral form, an ovary on one side and a testis on the 

 other. The glands are, almost without exception, markedly altered and 

 without function. The accessory genital organs may show any degree of 

 associated abnormality, usually with characteristics of both sexes. It is 

 said that the bilateral and unilateral forms have never been observed 

 in man. 



PseudoJiermaphroditism is called masculine or feminine, according to
