Abstract

Granular cell tumor is an uncommon neoplasm with uncertain histogenesis that rarely occurs in the orbit. Although it is regarded as a benign lesion, one case of malignancy has been recorded. The authors present a case of recurred, infiltrating orbital granular cell tumor in a 39-year-old woman. On light microscopic examination, the tumor cells showed the characteristic findings of granular cell tumor, but there were hyperchromatic and pleomorphic nuclei with unusual mitotic figures, suggesting a malignant nature.
