Oral Candidiasis Diagnosis and Presentation

Classic Presentations of Oral Candidiasis

The American College of Physicians recommends recognizing oral candidiasis by its classic presentations, including pseudomembranous candidiasis, which appears as creamy white, plaque-like lesions on the buccal mucosa, oropharynx, or tongue surface that can be scraped off, and erythematous candidiasis, which appears as red patches without white plaques, typically visible on the palate or diffusely on the tongue 1, 2
The Infectious Diseases Society of America notes that angular cheilitis, characterized by inflammation and cracking at the corners of the mouth, is also a recognized clinical pattern of oral candidiasis 1, 2

The European Society of Clinical Microbiology and Infectious Diseases states that ulceration is not a primary feature of oral candidiasis but can develop when oral candidiasis progresses to esophageal candidiasis, with endoscopic examination revealing whitish plaques that progress to superficial ulceration of the esophageal mucosa with central or surface whitish exudates 1, 2

The Centers for Disease Control and Prevention recommends evaluating suspected oral candidiasis by looking for characteristic features, such as white plaques that scrape off easily or red patches on the tongue or palate, and considering alternative diagnoses if ulcers are present without white plaques 1, 2
The American Academy of Oral Medicine suggests that if ulcers persist despite antifungal treatment, a biopsy should be obtained to exclude other etiologies 3
