What condition is referred to as cheilosis?

1. Dryness of the lips

2. Cracking of the corners of the mouth

3. Inflammation of the lips

4. Swelling of the tongue

The correct answer is: Inflammation of the lips

Cheilosis specifically refers to a condition characterized by cracking and sometimes blistering at the corners of the mouth, commonly known as angular cheilitis. While the term might suggest a broader range of lip issues, including inflammation or swelling, it is primarily associated with the cracks and fissures that appear, particularly due to factors such as nutritional deficiencies (like B vitamins), infections, or irritation. In the context of the options provided, the best match to the condition known as cheilosis is the cracking of the corners of the mouth. Dryness of the lips can occur as a symptom or a related issue but does not capture the specific signature of cracks as seen in cheilosis. Similarly, inflammation of the lips and swelling of the tongue describe different oral conditions that are not encompassed by the specific features of cheilosis.
