Residency Program - Case of the Month
February 2010 - Presented by Mary Tomic, M.D.
Clinical history:
The patient is a nulligravida 47 year old female with Turner's Syndrome who presented with a 10 month history of irregular vaginal bleeding. Gynecologic history is further significant for menarche at age 15 with premarin and provera; the patient stopped hormone replacement therapy in her twenties with subsequent cessation of menstruation. Physical exam was significant for obesity; pelvic exam did not reveal any abnormalities but was limited. Endometrial biopsy revealed adenocarcinoma and the patient subsequently underwent a total abdominal hysterectomy.
Gross description:
Received fresh was a 34 gm hysterectomy specimen consisting of uterus and bilateral fallopian tubes. The ovaries were not grossly identified. Bivalving of the uterus revealed a polypoid mass involving the posterior lower uterine segment. On cut section the mass involved greater than 50% of the myometrial surface.
