Palisaded, encapsulated neuromas of the skin

The palisaded, encapsulated neuroma is a clinically distinctive, solitary, benign cutaneous tumor. It occurs with equal frequency in both sexes but its anatomic distribution is limited, with rare exceptions, to areas bordering mucocutaneous junctions, predominantly on the face. It is a histologic simulant of some of the lesions in the multiple, mucosal neuromata syndrome. It is classified as a primary hyperplasia of nerve fibers (axons and their sheath cells).
