Whereas ovarian tumors with overt endocrine manifestations account for less
than 5% of all ovarian neoplasms, the incidence of virilizing type tumors
in postmenopausal women is even lower since the average age of occurrence i
s 43 years. Steroid cell tumors not otherwise specified (NOS) are even more
rare. We report the case of a 56-year-old woman (age of onset of menopause
43 years) who consulted our service due to a hyperandrogenic syndrome: dee
pening of the voice, temporal balding, hirsutism and cliteromegaly. Laborat
ory findings indicated hyperandrogenism in male range.
The dexamethasone suppression test did not modify, basal values, indicating
that adrenal origin was unlikely. Transvaginal ultrasound disclosed multip
le microcysts in the left ovary. Abdominal tomography was normal. Suspectin
g an ovarian tumor, bilateral oophorectomy was performed and a pediculate,
3 cm in diameter, was encountered in the left ovary. Histopathological stud
ies determined it to be a virilizing ovarian tumor NOS. Postoperative recov
ery was fast; normal hormonal valves were reached together with visible cli
nical improvement. This case is reported because this type of tumor is very
infrequent in postmenopausal women, and because in this case it was the fu
nctional hormonal test that allowed tumor localization.
