Perniosis (chilblains) masquerading as CA-MRSA: A case report

Abstract

Perniosis (chilblains) is a vasospastic, inflammatory disease that occurs when the skin is subjected to cold above the freezing point, under damp conditions. Erythematous (violaceous) blisters, ulcerations or pustules that sit on an edematous base, accompanied by pain, burning or itching, are usually evident. To the inexperienced clinician it may resemble community-associated methicillin-resistant Staphylococcus aureus and could lead to inappropriate treatment. Here we report such a case. © 2009 Bohman et al; licensee Cases Network Ltd.
