(a, b) Lesions on the tongue (4 x 2 cm and 3 x 2 cm) with slightly rolled and raised edges. (c) High-power view of a Gomori methenamine silver stain (GMS). Biopsy from ulcerated vocal cord lesion demonstrates spherical to oval yeast cells, some of which are budding. (d) High-power view of a Kinyoun stain. Round ascospores (arrowhead) inside the asci that are characteristic of S. cerevisiae.

It gradually increased in size and the patient noticed 2 new lesions (3 x 2 cm and 4 x 2 cm), one on either side of the tongue (Figures 1 and 1). Abundant extracellular oval budding yeast forms were seen on hematoxylin and eosin and Grocott's methenamine silver stains (Figure 1). Kinyoun stain revealed oval asci with 1-4 ascospores inside, a characteristic finding of Saccharomyces genus (Figure 1).
