Suture reaction masquerading as a conjunctival malignancy.

CASE REPORT: We report a case of conjunctival inflammation secondary to a retained suture masquerading as a neoplastic lesion. Excisional biopsy was performed in the right eye on a superior bulbar conjunctival lesion that appeared to be a conjunctival malignancy. A past history of ptosis surgery was obtained. Careful repeated examination with anesthesia, applying traction to the forniceal conjunctiva, revealed an occult polypropylene suture. Despite clinical features typical of malignancy, histologic examination revealed only chronic inflammatory cells. COMMENTS: Patients with suspicious conjunctival lesions and a history of ptosis surgery should be carefully explored for retained suture fragments. Examination with anesthesia may be needed to find an occult suture.
