- Abstract
A case of endometrial adenocarcinoma simulating microglandular hyperplasia (MGH) of the cervix is presented. A postmenopausal 53-year-old woman, with no previous history of taking exogenous hormones, presented with vaginal bleeding. An endometrial biospy exhibited a tumor composed predominantly of a microglandular proliferation of tightly packed glands with mild to moderate atypia and mitotic figures. The majority of the tumor cells contained intracytoplasmic mucin. There were numerous neutrophils within the microglandular lumens and in the stroma. The tumor was focally positive for carcinoembryonic antigen and vimentin. The MGH-like proliferation, focally, had a transition to a conventional mucinous adenocarcinoma. Hysterectomy specimens showed a residual mucinous endometrial adenocarcinoma with no myometrial invasion, the uterine cervix was unremarkable. Four years following her hysterectomy the patient was well, with no evidence of disease. Pathologists need to be cautious about MGH-like changes in the endometrial biopsy of postmenopausal women and be aware of this type of endometrial cancer as it may be misdiagnosed.
