Estrogen-secreting adrenocortical tumor in a postmenopausal woman: a challenging diagnosis
2021
Summary Adrenocortical carcinoma (ACC) is a malignant disorder with rapid evolution and severe prognosis in adults and most produce cortisol and androgen. Estrogen-secreting adrenocortical carcinomas are extremely rare, especially in women, tend to be larger and have worse prognosis compared with other types of ACCs. We report the case of a 58-year-old woman who presented with bilateral breast enlargement and postmenopausal genital bleeding. She presented high estradiol (818 pg/mL - 25 times above upper normal limit for postmenopausal women) and testosterone (158 ng/dL - 2 times above upper normal limit) levels and no suppression of cortisol after overnight 1 mg dexamethasone test (12.5 µg/dL; normal reference value: Learning points Estrogen-secreting adrenocortical carcinomas are exceedingly rare in adults and account for 1-2% of adrenocortical carcinomas. Estrogen-secreting adrenal tumors can be present in females, but are even more rare, we found few cases described in the literature. In women, they present with precocious puberty or postmenopausal bleeding. Feminization in the context of an adrenal tumor is considered almost pathognomonic of malignancy. Feminizing ACCs tend to be larger and with worse prognosis compared with nonfeminizing ACCs.
