Localized Linear IgA Bullous Dermatosis and a Recurrent Cicatricial Ectropion of the Eyelid: A Case Report of a Sixteen-Year Follow-up

Cicatrizing ectropion of the eyelid is an uncommon condition, possibly resulting in significant ocular morbidity. A potential cause can be a systemic disease, including autoimmune blistering disease (ABD). We herein report a case with a sixteen-year follow-up of a patient with a chronic cicatrizing unilateral ectropion caused by linear IgA bullous dermatosis (LABD). LABD is an ABD, characterized by the accumulation of IgA anti-basement membrane autoantibodies. It has a varied presentation; however, localized or ophthalmic manifestations have been infrequently described. The case demonstrates the benefits of immunohistochemistry in obtaining the correct diagnosis, and difficulties in the medical and surgical management of a recurrent cicatricial ectropion caused by chronic systemic disease.
