Livedo reticularis is a common side effect of treatment with amantadine for Parkinson's disease. Investigation of 40 such patients suggests that the livedo is a physiological response provoked by depletion of catecholamine stores in peripheral nerve terminals.

Livedo reticularis (LR) is a "fish-net like" mottling of the skin, and is attributed to a variety of factors. Amantadine, a medication used in Parkinson's disease, has been known to cause LR localized to the lower, and to a rarer extent, the upper extremities. Patient perception of this condition has been severely under-reported and can impact the patient's decision to stop this medication. In this retrospective study, we analyze the perception of five patients presenting with LR and their decision to continue on amantadine. It was seen that patients with the reticularis rash localized in the upper extremities, in addition to the lower extremities, were affected enough to discontinue amantadine despite its useful therapeutic effects. It is imperative that patient perception regarding LR be taken into consideration when initially presented. Furthermore, the decision to change the regiment of amantadine should be individualized according to patient condition and perception of presented rash.

Livedo 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.
