Exuberant conjunctival pseudopolyposis in a patient with dermatomyositis.

Dermatomyositis is a disease of unknown cause, characterized by a diffuse inflammatory myopathy and skin changes consisting of heliotrope eruption, Gottron's papules, periungual telangiectasia with dystrophic cuticles, skin telangiectasia, and atrophy. Ocular involvement may consist of conjunctival edema, nystagmus, extraocular muscle imbalance (when associated with myasthenia gravis), iritis, cotton-wool spots, and optic atrophy. Conjunctival avascularity and membranous conjunctivitis also have been reported. We describe an unusual conjunctival finding with secondary corneal surface disturbances in a patient with dermatomyositis.
