Kim, Lee, and Oh: A Case of Granular Cell Tumor of the Orbit

Abstract

Purpose

To report a case of granular cell tumor of the orbit in a patient, complaining of foreign body sensation due to entropion.

Case summary

A 59-year-old man visited our clinic because of foreign body sensation in the right eye due to entropion. A white mass was noted at the right palpebral conjunctiva, and bulbar conjunctiva chemosis was seen. We performed excisional biopsy and capsulopalpebral fascia repair for lower lid entropion. Histopathological examination revealed a granular cell tumor. There were no complications after surgery.

Conclusions

Granular cell tumor of the orbit is rare, but it should be considered in the differential diagnosis of a mass lesion causing entropion or diplopia.
