Primary squamous cell carcinoma of the endometrium.
A rare case of primary squamous cell carcinoma of the endometrium, probably originating from adenomyosis, is presented. A 58-year-old Japanese woman was referred to Kitasato Institution Medical Center Hospital to explore the cause of her postmenopausal bleeding. The endometrial cytology specimen obtained with the Endocyte (an device for endometrial check up) showed cells suggesting well differentiated squamous cell carcinoma. The patient underwent modified radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy, followed by postoperative radiation therapy. The dissected uterus revealed keratinizing-type squamous cell carcinoma localized in the fundal portion of the uterine body and invading deeply into the myometrium, coexistent with a large area of adenomyosis with a transitional area to carcinoma. The residual endometrium was atrophic. There was no atypical finding in the cervix. Human papilloma virus DNA was not detected. The carcinoma recurred 26 months after the surgery, and the patient died of the disease.
