Background: Progestin or estrogen-progestin combination therapy has no
t proven useful in the treatment of endometriosis of the abdominal sca
r after cesarean delivery. We report our experience in managing this c
ondition with a gonadotropin agonist. Case: A 22-year-old black woman
with a history of two previous cesareans developed endometriosis of th
e abdominal scar. The extent of the lesion was estimated by computed t
omographic (CT) scan, and a 6-month preoperative course of leuprolide
acetate was administered. The patient exhibited prompt symptomatic res
ponse to the gonadotropin agonist, but the physical examination and CT
scan findings were unchanged. Pathologic examination after surgical r
emoval of the lesion confirmed the clinical diagnosis. Conclusion: Leu
prolide acetate administered to a patient with cesarean scar endometri
osis was associated with an improvement in symptoms, but there was no
change in lesion size.
