Abstract
Ichthyosis uteri is an exceedingly rare condition in which the entire surface of the endometrium is replaced by stratified squamous epithelium. It is a benign lesion and its association with benign and malignant conditions has been reported in the literature (Bewtra, Xie, Hunter, Jurgensen (Arch Pathol Lab Med 29:e124-e125, 2005)). Originally described as an endometrial response to iatrogenically introduced caustic substances, similar changes have since been described in association with a variety of inflammatory conditions of the endometrium. It is concluded that a squamous cell carcinoma of the cervix extended proximally into the endometrium (Bagga, Jaswal, Datta, Mahajan (Indian J Pathol Microbiol 51:267-268, 2008)). The possibility of significant cervical pathology should be considered when plaques of squamous epithelium with low-grade dysplastic changes are identified in an endometrial biopsy or curettage.
