Extratarsal presentation of chalazion.

PURPOSE: We report a case of atypical, extratarsal chalazion referred with a history of a chronic inflammatory mass found on the edge of the lower eyelid.

METHODS: A 3-year-old female developed a small mass on the medial side of the right lower lid in 4-month duration. She was seen by her ophthalmologist and the diagnosis of a chalazion was made. Over the ensuing one month with warm compression, the lesion subsided and the new lesion appeared away from the edge on the lateral eyelid 3 months ago.

RESULTS: She underwent surgery and drainage was performed. We found a track, a proof of migration, on the lower tarsal conjunctiva in the medial side of the right eyelid during surgery.

CONCLUSIONS: Long-term observation in chalazion may induce migration with tract and express as an atypical chalazion.
