Abstract
PURPOSE We are conducting a prospective study trying to determine, in both sexes, the frequency of appearance of ectopic Leydig cells, their preferred location, their relationship with nerve structures and the possible causes of their appearance. METHODS We have studied 86 cases that were removed according to different clinical indications for pathological study: uterine leyomiomas (n = 12), ovarian cystadenoma (n = 4), endometrial hyperplasia (n = 8), endometrial carcinoma (n = 12), cervical carcinoma (n = 4), seminoma (n = 4), fallopian tube ligatures (n = 24), vasectomies (n = 8), nonspecific orchiepididymitis (n = 2), and unknown (n = 8). RESULTS We have observed ectopic Leydig cells in 13/86 cases (15.11%), 9/72 in the female samples (12.50%) and 4/14 in male samples (28.57%). The most frequent location was the mesosalpinx (4 of 13: 30.76%). CONCLUSIONS These high figures lead us to believe that the ectopia of Leydig cells is not really a pathologic entity, but a finding related to specific functions yet to be determined.

Abstract
Testosterone secreting tumours of the adrenal glands are usually adrenal carcinomas or adenomas. Here we report the rare case of an adrenal ganglioneuroma with ectopic Leydig cells, a so-called virilizing adrenal ganglioneuroma. Clinically it is characterized by symptoms of virilization, histologically by the occurrence of a population of eosinophilic cells. In the absence of crystalloids of Reinke this cell population can be identified as Leydig cells based on positive immunohistochemical staining of inhibin and calretinin.
