Abstract

Granular cell myoblastoma in the orbit is an extremely rare disease. One such case is reported here. Radiological and computerized tomographic appearance, findings at surgery, and pathology are presented, and treatment of this lesion is discussed. The surgical findings strongly indicated the cytological origin of this tumor to be the peripheral myelinated nerve.
