Findings from a biopsy specimen of a nodule on the left ear revealed suppurative granulomatous dermatitis. No polarizable foreign material was identified. Special stains for bacteria and acid-fast bacilli were negative for organisms. Gomori methenamine silver stain revealed rare budding yeast forms (Figure 3). Tissue fungal culture grew Sporothrix schenckii. Septate hyphae with conidia arranged in rosettelike clusters were seen on lactophenol aniline blue stain. The patient reported no trauma to the ear but was a gardener. She was treated with oral itraconazole, 200 mg/d, and demonstrated marked improvement over the first several weeks of therapy.
