Periocular Granuloma Annulare: A Case Report of a Rare Childhood Disease in an Adult.

A 21-year-old female presented to the oculoplastic clinic with a 2-year history of raised lesions in the right upper eyelid and lateral canthus area. Due to their unusual appearance, the patient underwent an excisional biopsy of the lateral canthus lesion. A diagnosis of granuloma annulare was made after histopathology demonstrated palisading epithelioid granulomas with central fibrinoid necrosis and Alician blue positive acid mucin. Granuloma annulare is a benign inflammatory skin condition characterized by firm discolored papules or nodules classically arranged in an annular pattern. Periocular involvement is extremely rare in adults and may pose a diagnostic challenge to ophthalmologists unfamiliar with its presentation and management.
