Angiofibromas in multiple endocrine neoplasia type 1.

Multiple endocrine neoplasia type 1 (MEN1) is a familial tumor syndrome with autosomal dominant inheritance. Cutaneous tumors in MEN1, which include multiple angiofibromas, collagenomas, and lipomas can easily be overlooked because of their subtle appearance. As markers of this tumor syndrome, recognition of the mucocutaneous manifestations of MEN1 is important in order to facilitate early interdisciplinary care and diagnosis of associated internal disease in both patients and family members.
