Q18.6: Macrocheilia

Macrocheilia, denoted by the ICD-10 code Q18.6, is a rare medical condition distinguished by the enlargement or thickening of the lips. It can be a congenital condition, meaning it's present at birth, or it could develop over time due to a variety of reasons such as inflammatory disorders, infections, or tumors. Visible as swelling or puffiness of one or both lips, macrocheilia can sometimes interfere with eating, speaking, and other oral functions. The severity and impact of macrocheilia on an individual's daily life largely depend on the extent of lip enlargement. Due to the vast array of potential underlying causes, the progression of the condition can vary significantly among individuals, affecting overall oral health and facial appearance. In some cases, macrocheilia might be seen in conjunction with certain systemic health disorders, thereby necessitating a comprehensive evaluation for diagnosis.
