전완 피부 신경을 침범한 신경림프종증

The term neurolymphomatosis has included infiltration of the peripheral nervous system by lymphoma. In generally, direct invasion of the peripheral nervous system is rare. The difficulty in treatment of neurolymphomatosis is due to unclassified characteristic symptoms and diagnosis. We performed excision of mass on the antebrachial cutaneous nerve with no specific symptoms. After diagnosis of diffuse large B cell lymphoma, further treatment and observation were followed. However, recurrence of the lymphoma was found in the ipsilateral forearm ulnar nerve, therefore we described a case of neurolymphomatosis with a brief review of the literature.
