A Case of Cutaneous Lymphadenoma as a Variant of Trichoblastoma / 대한피부과학회지

ABSTRACT

Cutaneous lymphadenoma is a benign epithelial neoplasm with lymphoepithelial infiltration that is supposed to be from a pilosebaceous origin. We report a 44-year-old man with a nodule on the pre-auricular area showing basaloid proliferation, intraepithelial lymphocytes and immature pilosebaceous structures. The findings of our case make it possible to diagnose a cutaneous lymphadenoma with follicular differentiation and supports this occurs as a variant form of nodular trichoblastoma with adamantinoid features.
