title: Case for diagnosis.
abstract: We report the case of a 58-year-old white female with Parkinson's disease. She evolved to an extensive livedo reticularis in the limbs and abdomen after commencing treatment with amantadine. We discuss the diagnostic approach to livedo reticularis and its differential diagnoses, emphasizing that the drug etiology must be considered when investigating livedo reticularis.
