title: Bilateral spectacle frame acanthoma.
abstract: We report the case of a young white male with bilateral retroauricular spectacle frame acanthoma which developed within a few weeks of wearing ill-fitting sunglasses. Bilateral cases have only rarely been reported. This lesion must be differentiated from malignant proliferative conditions.
