Abstract

Clinical and histopathological features of an ovarian endocervical - like mucinous borderline tumour (EMBT) are studied. A 31 - year - old women had a right cystic ovarian tumour with a portion of papillary proliferation at the inner wall. Peripheral blood carbohy drate antigen 125 (CA125) level was 44 U/ml, carcino-embryonic antigen (CEA) was 1.4 ng/ml, which were within a normal range. Carbohydrate antigen 19-9 (CA19-9) was 390 U/ml, an abnormally high level. A right adnexectomy was performed. Histopathological examinations showed that the tumour was an ovarian endocervical - like mucinous borderline tumour. The histopathological features of EMBT are papillary proliferation and the epithelium resembling endocervical cells. Additionally, immunohistochemical staining showed that the specimens were positive for CA19-9 and negative for CA125 and CEA. She is alive and well 2 years and 10 months after the operation.
