Résumé
The development of primary squamous cell carcinoma in the endometrium is extremely rare. In 1928 Fluhmann proposed three criteria to establish the diagnosis: (1) no coexisting endometrial adenocarcinoma, (2) no connection between the endometrial tumor and the squamous epithelium of the cervix and (3) no squamous cell carcinoma of the cervix present. More recently, the World Health Organization (WHO) updated Fluhmann's criteria by adding that the tumor must contain clear evidence of squamous differentiation, such as the presence of intercellular bridges and/or keratin. We have experienced a case of primary endometrial squamous cell carcinoma which fulfills Fluhmann's criteria and WHO's. In this report, we present the clinical and pathological findings of a case of a primary endometrial squamous cell carcinoma of a 62-year-old patient with a review of the concerned literatures.
