title: Dermoid Cyst and its bizarre presentation.
abstract: Dermoid cysts or mature cystic teratoma are the most common type of ovarian germ cell tumor usually occurring in the reproductive age group. They are commonly unilateral and 10-12 % can be bilateral. They are commonly multicystic and contain sebaceous fluid as well as tissue of three germ cell layers e.g. ectoderm (skin, hair, brain) mesoderm (muscle, fat ,teeth ,bone, and cartilage) and endoderm (mucious and ciliated epithelium).These teratomas usually arise from the gonads but has been found anywhere in the body. Their site, size and clinical presentations are extremely variable causing confusion with medical and surgical diseases, acute emergency due to rupture and torsion , bowel and bladder injuries, and pregnancy etc. The malignant teratoma occurs at 3-4% only among ovarian carcinoma. The malignant transformation in benign cysts is a rare occurrence with 1-2% cases and squamous cell carcinoma being the commonest. This review is undertaken to study the different presentations produced by these tumors.
