Blastomycosis-Like Pyoderma in a 59-year-old Male with Type 2 Diabetes Mellitus

Abstract

Blastomycosis-like pyoderma (BLP) is a rare cutaneous disorder that results from an exaggerated response to a bacterial infection, most commonly Staphylococcus aureus. There are a variety of reported predisposing factors, including diabetes, obesity, leukemia, primary immunodeficiency, and immunomodulatory therapy. Clinical and histopathological findings of BLP can be quite disparate, often resulting in a delay in diagnosis. We report here a case of a man who presented with an enlarging verrucous nodule of his neck, and was subsequently diagnosed with BLP. The purpose of sharing this case is to contribute to the existing literature of this rare disease by highlighting a unique presentation.
