ABSTRACT
AbstractLivedo reticularis is a spastic-anatomical condition of the small vessels which translates morphologically by a reticular pattern, interspersing cyanosis, pallor and erythema. The same can be congenital or acquired. Among the acquired, we highlight the physiological livedo reticularis and the idiopathic livedo by vasospasm; the latter configures the most common cause. The drug-induced type is less common. The drugs amantadine and norepinephrine are often implicated. Cyanosis is usually reversible if the causative factor is removed, however, with chronicity, the vessels may become permanently dilated and telangiectatic. We report a case of a patient diagnosed with Parkinson's disease with chronic livedo reticularis associated with the use of amantadine and improvement after discontinuation of the drug.

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.
Descreve-se caso clínico de paciente feminina adulta, portadora de doença de Parkinson em uso de amantadina que desenvolveu extenso quadro de livedo reticular nos membros e abdome após o início do medicamento. Discutem-se a semiotécnica diagnóstica do livedo reticular e seus diferenciais. Os autores salientam que a etiologia medicamentosa deva ser considerada no diagnóstico dos livedos reticulares.
