[Solitary encapsulated neuroma].

Solitary encapsulated neuroma (EN) is a true neuroma that is seldom diagnosed clinically. EN is the most frequently excised benign neuroma of the skin and has to be included in the differential diagnosis of small nodular facial tumours of middle-aged people. We report histological studies of 79 EN. EN are distinctive true neuromas that can easily be distinguished from all other benign neural neoplasms except the neuromas in the multiple mucosal neuroma syndrome.
