Unilateral localized amyloidosis of levator palpebrae superioris muscle causing blepharoptosis

Abstract

We report a rare case of unilateral localized amyloidosis of levator palpebrae superioris (LPS) muscle causing blepharoptosis. A 71-year-old male presented with a history of gradually progressing left upper eyelid ptosis. LPS resection was planned and the resected unusually thickened muscle was sent for histopathological examination which revealed amyloidosis. Investigations excluded systemic involvement. Amyloidosis should be considered in the differential diagnosis of aponeurotic ptosis.
