case_images: On physical examination, she had a crusted, ulcerated plaque on the right opisthenar (measuring 2x4 cm) and several macular papules and nodules on erythematous plaque (Figure 1A).  At our hospital, biopsy specimens revealed pseudoepitheliomatous hyperplasia and suppurative granulomas, and fungal elements were seen invading the dermis by PAS and GMS (Figure 1B-1D), but acid-fast staining was negative. The isolates were cultured on SDA plates at 28 C for 7 days, microscopic morphology showed septate, bamboo-like hyphae, and no spores were found (Figure 1F).
