Management of cicatricial ectropion secondary to pyoderma gangrenosum.

Pyoderma gangrenosum is a rare condition with few cases of eyelid involvement reported in the literature. Pathergy is a well-recognised phenomenon that can trigger this condition. Pyoderma gangrenosum should be considered in cases of progressive cribriform cicatrisation where there is a history of antecedent trauma. Surgical management of a resultant ectropion may be challenging as a result of aggressive scarring and the risk of provoking a recurrence. We report a case of pyoderma gangrenosum causing a cicatricial ectropion, and discuss the underlying aetiology of iatrogenic incitement, and its implications for surgical management.
