Amiodarone-Induced Leukocytoclastic Vasculitis in a Decompensated Heart Failure Patient: A Case Report

Leukocytoclastic vasculitis (LCV) is a small-vessel vasculitis characterized by inflammation and damage to the walls of small blood vessels. It typically presents with palpable purpura and can be associated with various systemic conditions. Although its etiology is diverse, LCV has been associated with systemic diseases, infections, medications, and autoimmune disorders. Here, we present a case of LCV in a patient with decompensated heart failure. A 58-year-old man presented with progressively deteriorating swelling in both his lower limbs and scrotum, a persistent dry cough associated with minor ulcerative lesions on his shins, and a patchy rash with pustules and flat reddish spots. He was hospitalized three days prior due to atrial fibrillation and rapid ventricular rate, for which he was commenced on amiodarone. This rash persisted for three days, yet he denied experiencing any discomfort or itchiness along with it. Based on his clinical picture, laboratory evaluations, and imaging findings, he was diagnosed with LCV induced by amiodarone.

Small-Vessel Vasculitis After ST-Segment Elevation Myocardial Infarction

We report a case of cutaneous small-vessel vasculitis in a patient treated with clopidogrel after an ST-segment elevation myocardial infarction and with amiodarone caused by persistent atrial fibrillation 6 weeks before. (Level of Difficulty: Intermediate.)

Amiodarone-induced cutaneous leukocytoclastic vasculitis: a case report and a review of the literature

Amiodarone can be used in a variety of arrhythmias. Given its widespread use, the probability of clinicians encountering its cutaneous adverse effects is high. A few cases of amiodarone-induced cutaneous vasculitis were reported in the literature, probably because it is underdiagnosed in clinical practice. Indeed, amiodarone-related cutaneous reactions may present a wide range of manifestations and are sometimes difficult to diagnose. Herein, we report a case with a sizeable necrotic ulcer on the left lower leg shortly after amiodarone exposure. A rigorous diagnostic study was performed before concluding the diagnosis of amiodarone-induced cutaneous vasculitis, which showed the histopathological features of leukocytoclastic vasculitis. The lesion was almost completely healed by the third month of discontinuation of amiodarone. We did a literature search and found seven cases which were reported as leukocytoclastic or lymphocytic vasculitis. We reviewed previous cases and presented our case in comparison to prior cases.
