Anterior Labial Commissure Tumors

The anterior labial commissure is the corner where your upper and lower lips meet at the front of your mouth. Think of it as the tiny “V” shape formed where the lips join near your nose.

An anterior labial commissure tumor is an abnormal growth that occurs at the corner of the mouth where the upper and lower lips meet. These tumors can be benign (non-cancerous) or malignant (cancerous). They may affect anyone but are more common in older adults and those with certain risk factors.

Pathophysiology

Structure

The anterior labial commissure is made up of skin, muscle, and mucous membranes. It plays a crucial role in movements like smiling, talking, and eating.

Blood Supply

This area receives blood through branches of the facial artery, ensuring that tissues get the oxygen and nutrients they need to function properly.

Nerve Supply

Nerves from the facial nerve provide sensation and control muscle movements in the anterior labial commissure, allowing you to move your lips smoothly.

Types of Anterior Labial Commissure Tumors

1. Benign Tumors:
   • Papilloma: A small, wart-like growth caused by a virus.
   • Fibroma: A firm, non-cancerous growth made of fibrous tissue.
   • Lipoma: A soft, fatty lump under the skin.
2. Malignant Tumors:
   • Squamous Cell Carcinoma: A common type of skin cancer that can affect the lips.
   • Basal Cell Carcinoma: A slow-growing skin cancer rarely found on the lips but possible.
   • Melanoma: A serious form of skin cancer that can develop in the lip area.
