Removal of an atypical ovarian dermoid cyst: a case report.

Ovarian dermoid cysts, also known as mature teratomas, are benign embryonal tumors with a slow growth rate. They are the consequence of ectodermal components becoming trapped along with their closure sites and account for the most common germinative ovarian tumor in reproductive-aged women. These patients may have a reduced risk of morbidity if they receive an accurate diagnosis and extensive follow-up care. These cysts are often evaluated using one of the following imaging techniques: computed tomography, magnetic resonance imaging, pelvic ultrasonography, or transvaginal ultrasound. Laparoscopy and laparotomy are the 2 surgical procedures typically used to remove persistent or exceptionally large cysts. Leakage of cyst contents during surgery is a common postoperative complication that can seldom, but occasionally, results in chemical peritonitis. We discuss a case of a significant dermoid cyst that developed in an older woman and was successfully removed via laparoscopic surgery. This instance is instructive for other physicians who may encounter a similar pathology.
