[Lympho-epithelial skin tumor. Case report with review of the literature and nosologic discussion].
The clinical and histological findings of a lymphoepithelial tumor of the skin are presented and compared to the 11 cases already published in the literature. This review permits to point out the main characteristics of this recently described tumor. In 10 of the 11 cases the tumor is located on the face. The diagnosis of basal cell carcinoma is most often evoked. The mean age is 40 and 9 of the 11 cases are women. The tumor histologically presented as an epithelial proliferation of basaloid cells with peculiar features: cyst-like cavities infiltrated by mononuclear cells, histiocytic and lymphocytic cells; marks of pilosebaceous differentiation: curling of epithelial cells, areas of keratinisation, large clear cells of sebaceous aspect. The origin of this tumor is discussed and the hypothesis are oriented towards a rare histological form of basal cells carcinoma or a hair adnexial tumor. New cases would provide more informations to specify the nosological place of this tumor.
