Oral Manifestations of Multiple Endocrine Neoplasia 2B Syndrome: A Rare Case Report.

Abstract

Multiple endocrine neoplasia (MEN) 2B syndrome is a rare autosomal dominant hereditary condition of neuroendocrine origin characterized by pheochromocytoma, marfanoid habitus, and mucocutaneous neuromas. Multiple mucosal neuromas on the tongue, lips, cheeks, and inner eyelids are often appeared as the earliest signs in most of the undiagnosed cases. Early diagnoses, recognition of phenotype, adequate surgery, and appropriate genetic counseling are very much essential as patients often develop medullary thyroid carcinoma (MTC) and pheochromocytoma. This case report would highlight the oral manifestations of MEN 2B in a 22-year-old female patient with multiple mucosal neuromas and a previous history of thyroidectomy due to MTC.
