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.
Mature teratoma (dermoid cyst) containing well-differentiated structures : respiratory epithelium and nervous tissue - brain. (H&E, ob. x10)
Benign microcystic teratoma of the ovary (II)
Mature teratoma (dermoid cyst) containing well-differentiated structures : respiratory epithelium, hair follicle and smooth muscle. (H&E, ob. x20)
Benign microcystic teratoma of the ovary (III)
Mature teratoma (dermoid cyst) containing well-differentiated structures : stratified epithelium, hair and fat tissue. (H&E, ob. x20)
