title: Congenital subcutaneous dendritic cell rich lymphoepithelial hamartoma.
abstract: We present the clinical, radiologic, histologic, immunohistochemical, and ultrastructural characteristics of a congenital pretibial subcutaneous lesion composed of a mixture of T and B cells, epithelial cells, and dendritic cells, probably representing a hamartoma. After total removal, there has been no recurrence. The prominent dendritic component of this lesion, demonstrated immunohistochemically and ultrastructurally, separates the lesion from cutaneous lymphadenoma and other adnexal tumors.
