Saccharomyces cerevisiae Laryngitis and Oral Lesions in a Patient with Laryngeal Carcinoma

Saccharomyces cerevisiaeis increasingly being promoted as a nutritional supplement by health food enthusiasts and is also recommended as prophylaxis against antibiotic-associated diarrhea. However, severe opportunistic infections due toS. cerevisiaehave been reported in patients with chronic disease, cancer, and immunosuppression. Fungemia, endocarditis, pneumonia, peritonitis, urinary tract infections, skin infections, and esophagitis have been described. It is important to consider infections due toS. cerevisiaein appropriate clinical settings. Here, we describe the first case ofS. cerevisiaelaryngitis in a patient with a history of laryngeal carcinoma who also had oral lesions.
