Desmoplastic malignant melanoma of the upper eyelid.
Desmoplastic melanoma is a rare and unusual variant of malignant melanoma. Its occurrence has not been previously reported in the ophthalmological literature, nor has an occurrence previously been shown to arise from mucosal melanosis. A case is reported of a patient who appeared to have a recurrent chalazion. The clinician should be alert to this entity when evaluating nodular eyelid lesions especially in the presence of acquired melanosis.
