摘　　要：Background.Mature cystic teratoma of the ovary(MCTO)is the most common ovarian germ cell n eoplasm and is usually diagnosed in early adulthood.Malignant transfor-mation is rare,occurring in approximately 2%of all cases.Though malignant transformation ca n occur from any of the embryonic germ layers,the most comm on malignancy arising in these otherwise benign tu mors is squamous cell carcinoma.Case.We present a patien t with aMCTO where malignant transformation of gastro intestinal epithelium re-sulted in moderately differentiate d adenocarcinoma.After 3years of follow-up,she remains free of disease.Conclu-sion.Although gastrointestinal ep ithelium is often found in MCTOs,adenocarcinoma arising from this cell type is un-common.This is the third reported ca se of adenocarcinoma arising in gastrointestinal epithelium of a MCTO.Background.Mature cystic teratoma of the ovary(MCTO)is the most common ovarian germ cell n eoplasm and is usually diagnosed in early adulthood.Malignant transfor-mation is rare,occurring in approximately 2%of all cases.Though malignant transformation ca n occur from any of the embryonic germ layers,the most comm on malignancy arising in these otherwise benign tu mors is squamous cell carcinoma.Case.We present a patien t with aMCTO where malignant transformation of gastro intestinal epithelium re-sulted in moderately differentiate d adenocarcinoma.After 3years of follow-up,she remains free of disease.Conclu-sion.Although gastrointestinal ep ithelium is often found in MCTOs,adenocarcinoma arising from this cell type is un-common.This is the third reported ca se of adenocarcinoma arising in gastrointestinal epithelium of a MCTO.
