Endocrine features of an adrenal-like tumor of the ovary.
Detailed in vivo endocrine studies of a virilizing adrenal-like tumor of the ovary are reported. A nonspecific steroidogenic baseline profile was observed in the face of clearcut histological adrenal-like features. Dynamic testing disclosed incomplete dexamethasone-related steroidogenic suppression suggestive of partial tumoral autonomy. At the same time, the observation of sizable dexamethasone-related steroidogenic decrements, unaccounted for by normal adrenal contribution, may be interpreted to suggest a direct, pharmacological, inhibitory effect of dexamethasone on tumoral and/or ovarian stromal steroidogenesis. These observations confirm the limited role of baseline steroid profiling and dynamic testing in the preoperative localization of androgen-secreting tumors. Reversible dysfunction of hypothalamic gonadotropic feedback mechanisms was suggested by combined single dose LRH-clomiphene testing. Complete resolution followed tumor removal.
