Eruptive hidradenoma.
This case report emphasizes two clinical findings that aid in the diagnosis of eruptive hidradenoma. They are the predilection of the lesions for the anterior rather than posterior surface of the trunk and the presence of milialike inclusions within the papules. Eruptive hidradenomas are appendageal tumors that differentiate toward intraepidermal eccrine ducts and the milialike papules represent dilated cystic ductal structures. This patient had concomitant involvement of the eyelids, which has been observed in some, but not all, cases of eruptive hidradenoma.
