THIS PRESENTATION is based on four cases of peculiar fibroepithelial tumors which were encountered among more than 900 epitheliomas examined during the three years from November, 1947, to November, 1950. It is believed that these tumors do not constitute a truly new entity, but, rather, that they are an unusual variety of basal-cell epithelioma. Similar cases doubtless have been seen by others and either did not attract particular interest or were interpreted in a different way. A fairly thorough search of the literature revealed two similar cases1 and one with similar histologic features.2 Other reports may have been missed, but no clearcut reference to this type of tumor was found in current textbooks or in recent discussions of epitheliomas.
The following cases were believed worthy of study because they presented diagnostic difficulties clinically as well as under the microscope, because the tumors exhibited unusual relations between parenchymatous and
