This case highlights an unusual presentation of Kimura's disease involving the orbit, mimicking a late recurrence of choroidal melanoma and likely related to an orbital implant.

Suspected late orbital melanoma recurrence warrants biopsy to exclude Kimura's disease; extends differential diagnosis in implant recipients.
A 54-year-old man underwent enucleation of the right eye in 1975 for a malignant melanoma of the choroid, with placement of an Iowa orbital implant. He presented in 1985, with the clinical appearance of a late orbital recurrence of the choroidal malignant melanoma. However, histologic examination revealed the orbital mass to be angiolymphoid hyperplasia with eosinophilia (Kimura's disease). Only six cases of orbital involvement, proved by pathologic studies, have been published in the ophthalmic English literature. This case represented an unusual presentation of a rare disorder that involved the orbit and was probably related to the orbital implant.
