[A case of conjunctival mucosal neuroma without multiple endocrine neoplasia]

Non-traumatic conjunctival mucosal neuroma (CMN) is usually complicated by multiple endocrine neoplasia (MEN). We report the first case of CMN without MEN type IIb (III). A 14-year-old Japanese girl had CMN in the conjunctival fornix of right eye. CMN was diagnosed from histopathology and immunohistochemistry. T1-weighted magnetic resonance imaging (MRI) showed a circular scribed iso-intensity signal, and the T2-weighted image showed iso-or high-intensity signal. There were no abnormal findings in the tongue, the neck or the abdomen.
