We report the case of a 70-year-old woman who was presumed to have right ov
arian testosterone-secreting tumor and was treated with long-acting gonadot
ropin-releasing hormone agonist therapy plus add-back hormone replacement t
herapy. The patient presented with various medical problems including hyper
tension, intracranial hemorrhage, myocardial infarction, unstable angina pe
ctoris, and poor control of diabetic mellitus and had exhibited rapid sympt
oms of androgen excess such as progressive hirsutism and bilateral temporal
balding for half a year. Tumor survey was negative except for an elevated
testosterone level. Renal vein catheterization successfully detected a righ
t ovarian androgen-secreting tumor. Because the patient was deemed medicall
y unable to tolerate surgery, she received an alternative treatment consist
ing of 6 months of gonadotropin-releasing hormone-agonist (GnRH-a) and add-
back hormone replacement therapy (HRT). Serum testosterone levels returned
to normal limits after administration of the first dose of GnRH-a. A follow
-up tumor survey was negative. The patient has been alive and free of disea
se for 8 months after six doses of GnRH-a. We conclude that this strategy m
ight be used as urgent therapy in a medically compromised patient with pres
umed ovarian androgen-secreting tumor. (C) 1999 Academic Press.
