The pustular disorders

Cutaneous simulants of infectious disease

Many cutaneous conditions can mimic infection. If these lesions are not accurately recognized, they may be treated with antimicrobial agents, which adds cost, potential risk, and inconvenience to the patient and the healthcare system. The presenting signs and symptoms of many ulcerating, pustular, morbilliform, bullous, neoplastic, granulomatous, autoimmune, and neutrophilic conditions, as well as clinical vasculitis, cellulitis, folliculitis, and panniculitis, have been mistaken for infection. This review emphasizes the clinical presentation, physical exam, and diagnostic workup of many of these conditions to assist the clinician in ascertaining the correct diagnosis. In addition, general treatment options are provided for each disease category.

Secondary cutaneous candidiasis with eosinophilia

Cutaneous candidiasis is a common skin infection caused by the Candida species, especially in intertriginous areas, and neutrophils usually infiltrate histopathologically. We describe a case of secondary cutaneous candidiasis which spread extensively to the trunk and extremities and showed marked dermal eosinophilia. This case and a similar reported case suggest that Candida can sometimes cause cutaneous inflammation predominantly composed of eosinophils.
