Ganglioneuroma Associated with Von Recklinghausen Neurofibromatosis / 대한피부과학회지

ABSTRACT

Ganglioneuroma is the benign tumor exclusively composed of fully differentiated mature ganglion cell, Schwann cells and fibrous tissue. It develops most commonly in the posterior mediastinum and retroperitoneum but cutaneous involvement is exceedingly rare. Cutaneous tumor showing ganglion cells includes the following three entities 1) primary ganglioneuroma, 2) well differentiated cutaneous metastasis from neuroblastoma, and 3) ganglioneuroma associated with von Recklinghausen's neurofibromatosis. Among them, the third has been considered as a neurofibroma with entrapment of ganglion cell. We described 2 cases of ganglioneuroma associated with von Recklinghausen neurofibromatosis and reviewed the histopathological and immunohistochemical findings.
