Where are angular fissures located in angular cheilitis?

• A. At the corners of the mouth
• B. On the inner aspect of the cheek
• C. Fissures at the corners of the mouth
• D. On the tongue

Answer: (C)

Angular fissures occur at the corners where the lips meet, the oral commissures. This location is prone to moisture, friction, and maceration from drooling or repeated lip movements, allowing infection by organisms like Candida or Staph aureus to cause the characteristic fissures. So the description "fissures at the corners of the mouth" best matches angular cheilitis. Fissures on the inner cheek or on the tongue describe different mucosal problems, not the angular fissures seen in this condition.
