What are benign cystic teratomas?

➢ Marked by the presence of mature tissues derived from all three germ cell layers: ectoderm, endoderm, and mesoderm. ➢ Usually these tumors contain cysts lined by epidermis replete with adnexal appendages—hence the common designation dermoid cysts. ➢ Most are discovered in young women as ovarian masses or are found incidentally on abdominal radiographs or scans because they contain foci of calcification produced by toothlike structures contained within the tumor
