Case Fourteen - Dermoid cyst. A 5 cm., rounded, lucent mass with a globular calcification in the configuration of a tooth is noted in the right aspect of the pelvis. Dermoid cyst, also referred as benign cystic teratoma, arises from germ cells of the ovary and it is composed of a combination of well-differentiated ectodetermal, mesodermal and endodermal elements such as skin, hair, teeth and fat.
Dermoid cyst is the most common type of germ cell tumor.
