description: A rare benign adnexal tumor that exhibits differentiation towards the follicular isthmus epithelium. It arises from the skin of the face and neck, and presents as multiple and, less often, solitary papules that are arranged in plaques. Morphologically, it is composed of anastomosing cords of pale epithelial cells. The cords are arranged horizontally in a fibrovascular stroma. At the periphery of the cords, small infundibular cysts are present.
