case_images: The physical examination revealed a greenish-black discolored patch covering the tongue with elongated "hair" on the dorsal side of tongue (Figure 1).
case_images: Direct fluorescence microscopy showed blastospores and pseudohyphae (A); On Sabourauds glucose agar at 27 C, cream-colored yeast-like colonies first developed in 3 days (B).

case_images: A large number of spores and hyphae were found under florescent microscopy (Figure 2A). By day 3, the large amounts of cream-colored yeast-like colonies appears on SDA and PDA (Figure 2B), but few bacterial colonies were found.

case_images: The lesion covered half of the outer edge of the nail plate with yellowish discoloration (A), after 3 months of therapy, and her thumbnail presented with green-black discoloration (B).

case_images: A 52-year-old woman reported to the Department of Dermatology with a chief complaint of thickening and discoloration on her right thumbnail, the big and little toenails on her right foot, and the middle and little toenails of the left foot for 5 months duration (Figure 3A). Instead, the affected area on the thumbnail exhibited an increase in size and greenish-black hue (Figure 3B).
case_images: Microscopic examination revealed sub-spherical budding yeast-like cells without pseudohyphae structure (A); Three days later at 27 C, creamy yeastlike colonies appeared on SDA plate (B).

case_images: Microscopic examination revealed sub-spherical budding yeast-like cells but no presence of pseudohyphae or hyphae structure in the specimen collected from her right thumbnail (Figure 4A). Repeated fluorescent microscopy examination of the nail samples revealed the same fungal structures as shown in Figure 4A. The repeated cultures yielded the same yeast-like colony appearance (Figure 4B).
