Angular Cheilitis

Angular cheilitis represents an inflammatory condition localized to the labial commissures, arising from multifactorial causes that include infectious, mechanical, allergic, nutritional, and systemic factors. This course reviews the manifestations of this condition, which include erythematous, fissured, or macerated lesions at the corners of the mouth, often accompanied by discomfort and functional impairment, as well as underlying etiologies including Candida albicans and Staphylococcus aureus, the most common pathogens, nutritional deficiencies, xerostomia, ill-fitting dentures, and immune compromise, which can predispose patients to this condition. Participants will gain an understanding of the clinical diagnosis, laboratory confirmation, red flags such as unilateral persistent lesions, recurrent infections, and associated systemic signs that require further investigation or referral. This course explores the complex etiology, diagnostic approach, and evidence-based management of angular cheilitis, including differentiating infectious from noninfectious causes, recognizing systemic and nutritional associations, and implementing targeted therapeutic strategies. This activity for healthcare professionals is designed to enhance the learner’s competence in recognizing angular cheilitis, performing the recommended evaluation, and implementing an appropriate interprofessional approach when managing this condition, thereby reducing recurrence and improving outcomes.
