case_images: Technology Animal Medical Center because of a solitary subcutaneous soft mass on the left side of the neck on day 1 (Figure 1). The cat was kept indoors with other two cats. The cat's owner noticed a mass approximately 1 cm in diameter three days prior, and the size of the mass increased until the visit.
case_images: Smear of the pus excreted from a subcutaneous abscess. Hyphae (allows) were observed with neutrophil and macrophage infiltration. Diff-Quik staining. x1,000.

case_images: Macro- and micro-morphologies of the clinical isolate of Exophiala dermatitidis from a cat with subcutaneous phaeohyphomycosis. (A) Colonies incubated on potato dextrose agar (PDA) at 35 C for 7 days. (B) Budding oval yeasts were observed under a microscope. Scale bars: 20 mum. (C) A colony incubated on PDA at 27 C for 7 days. (D) Brown septate hyphae produced conidiospores laterally or on the apex. Scale bars: 100 mum.

case_images: Morphologically, dark-green, waxy, smooth, yeast-like colonies developed at 35 C (Figure 3A). Budding oval yeasts were observed under a microscope (Figure 3B). A dark-green colony with aerial mycelium developed at 27 C (Figure 3C). Microscopic examination revealed brown septate mycelia and oval conidiophores (Figure 3D).
