Background and Objective: Endometriosis is a common
benign gynecologic disease in reproductive-aged
women. The clinical manifestations of endometriosis
are progressive dysmenorrhea, subfertility, and pelvic
masses. Most endometriotic cysts are less than 12
cm. in diameter. We report an unusual case of an
extremely large endometriotic cyst that gradually
enlarged to near term gravid uterine size over the
course of a year.
Case report: We report a 26-year-old female patient
with a gradually enlarging pelvic mass and progressive
dysmenorrhea. A whole abdominal CT scan was taken
before the operative procedure, and it revealed
an ovarian cancer-like complex mass that was 30
centimeters in diameter. The patient underwent exploratory
laparotomy with right salpingo-oophorectomy
and left ovarian cystectomy. The pathological
diagnosis was bilateral endometriotic cysts.
Conclusion: As endometriotic cysts might manifest
as ovarian cancer, they require careful management
and long-term follow up at least 5 years. Moreover,
intensive counseling about appropriate treatment is
very important. Especially young patients, should not
rush to decide on staging surgery based on the results
of radiographic examination alone
