Abstract
A case of desmoplastic trichoepithelioma of the upper lip investigated by histochemistry and immunocytochemistry is presented. There was his tologic suggestion of cytoplasmic vacuolation that does not appear to have been previously described. Histochemical examination indicated th e presence of glycogen within tumor cells and a reparative-type stroma . Immunocytochemical examination revealed variable reactivity for high molecular weight cytokeratin and colonization by Langerhans' cells. T he observations suggest a follicular and sudoriferous differentiation for desmoplastic trichoepithelioma and hence an origin from a pluripot ential adnexal keratinocyte.
