MEN2 is a cancer syndrome comprising three related clinical subtypes: (1) MEN type 2A (MEN2A; MIM# 171400) characterized by the association of medullary thyroid carcinoma (MTC), pheochromocytoma (Pheo), and hyperparathyroidism; (2) MEN type 2B (MEN2B; MIM# 162300), which includes MTC, Pheo, mucosal neuromas, ganglioneuromatosis of the digestive tract, and skeletal abnormalities; and (3) familial MTC (FMTC; MIM# 155240), defined by the sole occurrence of MTC.

This family of 11 individuals with familial MTC type of MEN 2A syndrome demonstrated the moderate risk RET p.Val804Met (protein valine at residue 804 replaced by methionine) genetic mutation, with 2 of the relatives presenting with dermal hyperneury, cutaneous lesions classically described in MEN 2B syndrome, and 1 relative also showing multiple sclerotic fibromas, a cutaneous manifestation of PTEN (phosphatase and tensin homologue) hamartoma-tumor syndrome.
