Abstract

The authors experienced a case of orbital granular cell myoblastoma in a 22 year old female, which is extreamely rare. The tumor mass had grown since 6 years ago in her right orbit. On ocular examination, the right eye was proptosed and displaced out and upward. Extraocular movements showed slight limitation of adduction of the right eye. The computed tomographic scanning revealed well defined hypervascular mass density in the right orbit. The mass was removed by modifiedkronlein approach and histopathologic examination revealed it to have features typical of granular cell myoblastoma.
