Primary Endometrial Squamous-Cell Carcinoma

Primary endometrial squamous-cell carcinoma (ESCC) is very rare. We report a case of a 60-year-old postmenopausal female who presented with abdominal distension with cervical discharge for 6 months. Peroperatively, her uterine cavity was filled with pus, which was subsequently drained. The uterus was cystic and had an irregularly folded inner surface. Microscopically, the endometrium showed extensive areas of carcinoma in situ with foci of micro invasion and emboli. There was no cervical lesion continuous with that of the uterus. This patient satisfied Fluhmann's criteria and was hence diagnosed as primary ESCC.
