A Case of Squamous Cell Carcinoma Arising in Benign Cystic Teratoma of the Ovary in a 27 Year Old Woman / 대한산부인과학회잡지

ABSTRACT

Squamous cell carcinoma arising in mature cystic teratoma of the ovary is an uncommon carcinoma that is histologically defined by the presence of squamous cell carcinoma within the mature cystic teratoma of the ovary. Although all three germ layers in benign cystic teratoma are thought to undergo malignant transformation, squamous cell carcinoma derived from ectoderm is by far the most common tumor. Clinical differentiation of malignant from benign mature teratomas, as well as from other ovarian tumors, is rarely possible preoperatively. The prognosis is generally poor but there is no consensus on optimal therapy and prognostic factor. We experienced one case of squamous cell carcinoma arising in benign cystic teratoma of the ovary in a 27 year old woman and report this case with a brief review of the concerned literature.
