Squamous cell carcinoma in situ lining the uterine cavity.

ABSTRACT

Cervical intra-epithelial neoplasia is a very common and well-known pathology. However superficial spreading of this lesion is very rare. The authors present a case of a 72-year-old woman with an abdominal mass, who had previously undergone a cervical conisation for a high-grade cervical intra-epithelial neoplasia. Anatomo-pathological examination of the mass showed a large distended fluid-filled uterus with the entire endometrium replaced by a high-grade squamous cell lesion. There were only micro-invasive foci found. The authors performed a literature search in PubMed with the following MeSH-terms "squamous cell carcinoma" and "endometrium". Other articles were selected out of the references of previously found articles. Only 31 similar cases were found. The presentation of the cases is varies extremely and a long-term prognosis is not yet known.
