Differential Diagnoses
Other Problems to Be Considered
Familial cutaneous collagenoma
Familial multiple lipomas
Multiple familial trichoepithelioma
Workup
Laboratory Studies
- The observation of multiple facial angiofibromas, collagenomas, and lipomas does not establish the diagnosis of multiple endocrine neoplasia type 1 (MEN1). These cutaneous findings indicate the need for further testing for MEN1 (and/or tuberous sclerosis, depending on the overall clinical picture), including both blood studies to examine for evidence of hormone hypersecretion and imaging studies to look for the presence of tumors. DNA testing is available but identifies a mutation in only about 80% of patients with familial MEN1.1
Procedures
- Skin biopsy may or may not be required, depending on the clinical appearance, the physician's experience, and whether the skin findings are being used to help establish the diagnosis of MEN1.
Histologic Findings
The histologic features of angiofibroma include dermal fibrosis, ectatic blood vessels, and stellate cells in the upper dermis.
The histologic features of collagenoma include increased amounts of collagen and normal or decreased numbers of elastic fibers. The features of the collagenoma may appear normal unless the biopsy sample includes surrounding healthy skin.
The histologic features of lipoma include a circumscribed nodule of uniform adipocytes.
