【 摘 要 】

A 53 year-old woman presented with a slowly progressive, painless proptosis OS. Computed tomography disclosed a round, homogeneous, well-delimited lesion in the inferior-temporal orbit. The tumor was composed of round cells with eosinophilic granular cytoplasm. Some of the cells had larger eosinophilic granules surrounded by a clear halo; known as pustulo-ovoid bodies of Milian or Bangle bodies. The diagnosis of a granular cell tumor was then established and confirmed by immunohistochemistry. Granular cell tumors are uncommon benign soft tissue neoplasms that have a predilection for the head and neck region. Awareness of the typical histopathological features is crucial for the correct diagnosis.
