[Argyrophilic cells in endometrial adenocarcinoma with foci of squamous cell metaplasia (adenoacanthoma)].

A case of well-differentiated endometrial adenocarcinoma with squamous cell metaplasia (adenoacanthoma) is described. Numerous argyrophilic cells in the squamous cell and glandular structures of the tumour-were detected by the Grimelius method. The tumour developed in a woman of 42, and was combined with uterine fibromyoma and ovarian mucinous cystadenoma. The data in favour of the common source of epithelial and argyrophilic cells are provided. The rationality of subdividing the tumours of this type into separate entries of different onconosological unities is discussed.
