Blastomycosis-like pyoderma

Abstract

A 9-year-old female, presented with recurrent bilaterally symmetrically distributed flesh colored vegetative plaques, papules and nodules on trunk and upper and lower extremities since 15 days. Investigations revealed anemia, hypoproteinemia, decreased albumin and positive D-xylose test. Pus swab and biopsy for culture sensitivity showed Enterococci species. Biopsy showed spongiotic psoriasiform dermatitis with subcorneal pustule. She fulfilled criteria for the diagnosis of blastomycosis-like pyoderma viz. presentation of large verrucous plaques with pustules and elevated border, pseudoepitheliomatous hyperplasia with abscess histologically and growth of one pathogenic bacterium on culture or tissue biopsy. She responded to long-term amoxicillin-clavulanic acid therapy.
