A Huge Mature Cystic Teratoma combined with Atypically Proliferating Mucinous Tumor of the Ovary

Abstract

Because of their high incidence of occurrence, benign cystic teratomas often occur coincidentally with other abnormalities of the ovary r uterus, and a common association has been noted with mucinous cystadenoma. However, the combination of cystic teratoma and serous cystadenoma is less common. The associated mucinous cystadenoma is most likely secondary to an overgrowth of gastrointestinal type epithelium, and some 4.5% of mucinous cystadenomas are associated with dermoid. We present here, with a brief review of the literature, a case of a huge mature cystic teratoma combined with ovarian mucinous cystadenoma, borderline malignancy.
