Abstract
We examined HE stained specimens of 6 cases of trichoepithelioma. In 2001, Ackerman advocated that trichoepithelioma was the cribriform type of trichoblastoma because both tumors consisted of follicular germinative cells. We checked the existence of the histopathological findings said to be commonly seen in trichoepithelioma and trichoblastoma. We think that the characteristics of the tumor cells and stroma that comprise the trichoepithelioma and trichoblastoma are the same and we agree with the hypothesis that trichoepithelioma is one type of trichoblastoma.
