ABSTRACT
El tumor de los cordones sexuales con túbulos anulares suele ser un tumor bilateral, de pequeño tamaño, calcificado, benigno y asociado con el síndrome de Peutz-Jeghers. Pero aquellos casos de presentación unilateral y de mayor tamaño, a pesar de su habitual aspecto anatomopatológico y comportamiento benignos, deben ser considerados como potencialmente malignos, y por tanto se debe efectuar un estrecho seguimiento de las pacientes que los presenten (AU)

We describe a case of cystic adenomatoid tumor of the uterus in a 38-year-old woman. The tumor was a subserosal cystic mass with a maximum diameter of 8 cm and located at the posterior wall of the right cornual region. Histologically, the tumor was composed of multiple cavities lined by flattened cells, lying among thin septa of connective tissue. The neoplasm showed small solid areas with a more typical histologic pattern of adenomatoid tumor. Immunohistochemical techniques showed the cells to be positive for keratins. They showed desmosomes, abundant intracytoplasmic filaments, and microvilli on ultrastructural study. The histologic, immunohistochemical, and ultrastructural characteristics of the present case closely resemble those of benign cystic mesothelioma and strongly support the mesothelial origin of the adenomatoid tumor of the uterus.
