Steroidogenesis in an Estrogen-Producing Adrenal Tumor in a Young Woman: Comparison with Steriod Profiles Associated with Cortisol- and Androgen- Producing Tumors
1990
There is only one previous report of an estrogensecreting adrenal tumor occurring in a woman during reproductive years. Our patient presented with mild hirsutism associated with menstrual bleeding every 3–6 weeks. The occurrence of apparently intermenstrual bleeding prompted an evaluation of estrogen levels. Markedly elevated plasma estrone levels were found (860–2305 pmol/L; normal, 50–340). Lesser relative elevations in 11-deoxycortisol and androstenedione were noted. Computed tomographic scanning of the adrenal glands identified a large tumor, which was subsequently resected. Estrone levels fell to 120 pmol/L, and all other abnormalities were corrected. Eighteen months after adrenalectomy, ovulation occurred regularly, and steroid levels were entirely normal. Steroid production in a cell suspension made from tissue obtained from the 190-g tumor was compared with that occurring in normal human adrenal cells. The production of estrone by the tumor cells was 40-fold greater than that by normal adrenal cel...
