Extraovarian steroid cell tumor 'not otherwise specified' as a rare cause of virilization in twelve-year-old girl.
BACKGROUND
We present a 12-year-old girl with a 5-year history of progressive virilization.


RESULTS
Regarding elevated plasma levels of 17-hydroxyprogesterone (17-OHP) and androgens, normal ultrasound and CT scan of ovaries and adrenal glands, the nonclassic form of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency was presumed the cause of virilization. As the glucocorticoid therapy did not normalize high levels of 17-OHP and androgens, and the DNA analysis did not demonstrate a mutation causing CAH, a laparotomy was performed. Near the right ovary a tumor was found and extirpated. Pathohistological studies determined it to be a rare steroid cell tumor, 'not otherwise specified'. Within the next months the signs of virilization resolved and menarche occurred.


CONCLUSIONS
Steroid cell tumor should be considered in differential diagnosis of virilization in childhood. Regarding the age of our patient and pathohistological findings of the tumor, her prognosis is favorable.
