Benign lymphoepithelial tumor of the skin ("cutaneous lymphadenoma").
"Benign lymphoepithelial tumor of the skin" or "cutaneous lymphadenoma" is a distinctive benign adnexal tumor presenting a characteristic combination of lobules of epithelial basaloid cells with a peculiar histopathological pattern and a dense intraepithelial T-cell lymphoid and histiocytic population. We report an additional example of this peculiar neoplasm. In addition to the characteristic histopathological features, focal areas showing unequivocal follicular differentiation were observed at the periphery of the tumor. In agreement with other authors we consider that this neoplasm should be included within the spectrum of neoplasms of pilosebaceous origin. Nevertheless, we consider that the original and simple concept of "benign lymphoepithelial tumor of the skin" seems more suitable and illustrative than the more widely used term of "cutaneous lymphadenoma" to define this rare benign adnexal neoplasm.
