Abstract
|
|
|
|
Multiple endocrine neoplasia type 2B (MEN2B), which is an autosomal dominant hamartoneoplastic syndrome, is a genetic syndrome. Patients with this syndrome are characterized by multiple mucosal neuromas on the tongue, lips, eyelid margins, and conjunctiva with marfanoid habitus, thick and protruding lips, open bite, and maxillary central diastema. Multiple oral mucosal neuromas are known to appear before the development of medullary thyroid carcinoma (MTC) or pheochromocytoma. Therefore, understanding the oral symptoms is very important for the early diagnosis of this syndrome. We report multiple submucosal neuromas in a 19-year-old male patient diagnosed with MEN2B and review this syndrome.
