Chronic laryngitis can present similarly to malignancy, so it is important to rule this out when clinical suspicion is present. While the prevalence of acute laryngitis is difficult to estimate with lack of reporting and conservative treatment measures, the annual incidence of chronic laryngitis is estimated to be 3.47 per 1000 people.
Infectious diseases to consider are croup, epiglottitis, diphtheria, pertussis, laryngeal tuberculosis, syphilis, leprosy, actinomycosis, candidiasis, blastomycosis, coccidioidomycosis, and histoplasmosis. Geographic and travel history can be useful in differentiating fungal infections.
Immunocompromised Patient Considerations:
Immunocompromised individuals are at particular risk for infectious laryngitis, particularly invasive fungal infection.
