Classically, granuloma annulare (GA) is a cutaneous disorder localized to the dorsum of the hands and/or feet in children and young adults. Very rarely it can present on the face and rarer still on periorbital structures such as the eyelid and orbital rim. Diagnosis hinges on clinical presentation and histological features, such as palisading granulomas with central destruction of collagen, presence of mucin and lymphohistiocytic infiltration. The etiology of this condition remains unknown, but may involve a delayed-type hypersensitivity reaction, malignancy and/or infection. Herein is the first reported case of an intraorbital GA in an 86-year-old male patient who presented with right eye proptosis.
