Mucosal Neuroma Syndrome without mutations of the RET-protooncogene: A histologic study on a case, supported by molecular genetic analysis.

2010

Mucosal neuromas are nerve hamartomas of the digestive tract and larynx, usually observed in the setting of Multiple Endocrine Neoplasia type 2B (MEN2B), i.e. in the presence of typical mutations and in association with medullary thyroid carcinoma, pheochromocytoma and marfanoid habitus. Exceptionally, they arise without the accompanying mutations and endocrine tumors, and in this paper we are reporting a histologic study on a case lacking the specific mutations. The patient was an adolescent girl with marfanoid habitus, with a left-sided epidermal nevus of the neck, and a bulging left upper lip and cheek. The left side of her tongue was considerably enlarged and studded with multiple protr…
