title: [Diagnostic problems in adenocarcinoma of the endometrium in women less than 40 years of age].
abstract: Endometrial adenocarcinoma in women under the age of forty presents a different course according to its histology. Adenocarcinomas of the endometrium may be classified into 4 main types: type 1, homologous or endometrioid; type 2, fallopian-like; type 3, cervical-like; type 4, unclassifiable. The majority of homologous adenocarcinomas have a relatively benign course, whereas the other types are definitely malignant. There is no room for doubt between adenocarcinoma and atypical endometrial hyperplasia in women under forty unless the histological pattern is of the homologous or endometrioid type, because the other patterns are definitely malignant.
