[Lymphoepithelial tumor of the skin].

Abstract

The authors report an additional case of lympho-epithelial tumor. First described in 1987 by Santa-Cruz et al., this tumor, also called cutaneous lymphadenoma, is rare. The mean age is 44. The lesion is generally located on the face and the clinical diagnosis of basal cell carcinoma is most often evoked. The tumor has a peculiar histological feature with cyst-like cavities composed by an epithelial proliferation and intraepithelial lympho-histiocytic cells. It is considered as a benign tumor. Its origin is still discussed but a pilosebaceous nature seems to be accepted.
