[The vanishing testis syndrome. Considerations on a case].
The aetiopathogenesis and clinical and diagnostic features of bilateral absence of the testicles in 46XY subjects are briefly reviewed. A eunuchoid 25-yr-old patient with male sex chromatin, 46 XY genotype, plasma testosterone slightly below normal, normal urinary 17-KS unaltered by gonadotropin stimulation, and bilateral absence of the testicles is presented. Examination of the inguinal canal showed a funiculus and ductus deferens residue terminating in an adipose mass. Section of the fibrous duct showed that this mass was full of capillaries and venules. Lesion between the 14th and 16th week of pregnancy is postulated.
