Clinical and pathological aspects of benign and malignant squamous epithelium of the corpus uteri; a report of two cases.

Two patients with primary squamous cell carcinoma of the uterus are described. In both patients, the disease was at an advanced stage when the diagnosis was made. Although endometrial malignancies with squamous elements account for 10-30% of endometrial carcinomas, primary squamous cell carcinoma of the uterus is extremely rare. Up to now fewer than 30 cases have been reported. The pathogenesis, morphogenesis and aetiology of squamous epithelium in the corpus uteri is discussed. Finally, some clinical aspects of the primary squamous cell carcinoma of the corpus uteri are reviewed.
