Synopsis

Angular cheilitis (perlèche) is a chronic inflammatory condition of the corners of the mouth (commissures) that is usually associated with a candidal or staphylococcal infection. The areas are generally slightly painful. The condition tends to last from days to months, depending on whether the patient seeks treatment. There may be concomitant intraoral candidiasis

Patients with diabetes mellitus, those who are immunocompromised, and those who have undergone head and neck radiation are prone to develop oral candidiasis, including angular cheilitis. 

Patients who wear dentures that do not adequately support the facial musculature are also prone to develop angular cheilitis. Patients will have accentuated folds at the corners of the mouth, leading to wicking of the saliva onto what is normally dry skin. The moist keratin acts as substrate that encourages fungal and bacterial growth.

Patients with iron, vitamin B12, zinc, and folate deficiencies are predisposed to this condition, although these represent a much less common cause for angular cheilitis.
