title: Retinitis pigmentosa and colon cancer: a previously unreported association.
abstract: Retinitis pigmentosa, a hereditary disease characterized by progressive retinal degeneration and blindness, has been associated with numerous diseases. We report the first association between retinitis pigmentosa and colon cancer in 3 of 53 hospitalized patients with retinitis pigmentosa at the Massachusetts General Hospital and Massachusetts Eye and Ear Infirmary for the period from 1962 to 1977.
