Curvilinear pigmentary lesions in a rod-cone dystrophy.

PURPOSE To report a peculiar curvilinear pigmentary lesion in the peripheral fundus in a rod-cone dystrophy. METHODS Observational case report. Fundus examination of a 57-year-old woman who was known to have a generalized rod-cone dystrophy since she was 8 years old. RESULTS The peripheral fundus examination revealed a curvilinear lesion which resembles a well-known finding associated with a presumed ocular histoplasmosis syndrome or multifocal choroiditis. CONCLUSIONS The differential diagnosis of a peculiar curvilinear pigmentary lesion in the peripheral fundus may be expanded to include a generalized rod-cone dystrophy.
