Benign microcystic teratoma of the ovary

Teratoma is a tumor which arises from tutipotent germinal cells. Frequently, it is localized in gonads (testis, ovary). It contains a variety of tissues (derived from one, two or three embryonic cell layers - mesoderm, endoderm or ectoderm), tissues which normally are foreign to the site of growth.
