Multiple endocrine neoplasia type 1 (MEN1) is a hereditary syndrome caused by pathogenic variants in the MEN1 gene and is associated with a combination of endocrine and nonendocrine tumors.In MEN1, tumors are most often found in the parathyroid gland, islet cells of the pancreas, and pituitary gland. Conclusions:  Multiple facial angiofibromas. NLM Dr Darling was a dermatology fellow at the National Institutes of Health during the study.

Objectives: National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Description. doi: 10.1067/mjd.2003.146. RESULTS: Multiple facial angiofibromas were observed in 28 (88%) of the patients with MEN1, with 16 patients (50%) having 5 or more. 28 As noted above, lipomas, collagenomas, and mucosal fibromas have been described in patients with BHDS. Multiple endocrine neoplasia type 1 (MEN1) is a familial tumor syndrome with autosomal dominant inheritance. MEN1 mutations in multiple endocrine neoplasia patients and clinical genetics MEN1 ... facial angiofibromas and collagenomas, and thymic, gastric, and bronchial carcinoids also occur. Multiple angiofibromas can no longer be considered pathognomonic for tuberous sclerosis. Collagenomas were observed in 23 patients (72%). It is caused by mutations in the MEN1 gene, which is a tumor suppressor gene. Multiple angiofibromas, collagenomas, lipomas, confetti-like hypopigmented macules and multiple gingival papules are cutaneous manifestations of MEN1 and should be looked for in both family members of patients with MEN1 and individuals with hyperparathyroidism of other MEN1-associated tumors. Multiple angiofibromas can no longer be considered pathognomonic for tuberous sclerosis. 2010 Mar;152A(3):657-64. doi: 10.1002/ajmg.a.33320. Lipomas.
