| Benign Cystic Teratoma |
|Treatment and Followup:|
|Benign cystic teratoma (Dermoid cyst) is quite common and comprises 12-15 % of all ovarian neoplasms. It usually occurs in the early reproductive years. Benign cystic teratoma is the most frequent ovarian neoplasm encountered in adolescence.
Dermoid cyst is usually asymptomatic. It may become large enough to produce local pressure and discomfort. Rarely, complications precipitate an emergent operation. The incidence of malignant transformation is less than 0.5 %.The most common malignancy is squamous cell carcinoma.
The treatment of dermoid cyst is surgical.Surgery may be laparoscopic or via laparotomy. Laparoscopic oopherectomy and cystectomy result in significantly shorter hospital stays and decreased hospital costs, but the surgery time is significantly increased compared to laparotomy.
Dermoid cyst is bilateral in 15-20 % of cases.
