Living with Cheilitis glandularis

A rare inflammatory condition of the lip with swelling and sticky mucus from enlarged salivary glands.

Understanding Cheilitis glandularis

Cheilitis glandularis is a rare inflammatory disorder of the lip.

It causes swelling of the lip with enlarged salivary glands, a clear thick mucus, and varying inflammation. Constant exposure of the lower lip lining to the environment can cause erosion, ulcers, crusting, and sometimes infection. In Caucasians it is linked with a relatively high chance of squamous cell carcinoma of the lip. It occurs at a variety of ages.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Thick, swollen lower lip
  • Enlarged salivary glands
  • Clear, thick mucus
  • Lip erosion, ulcers, and crusting
  • Squamous cell carcinoma of the lip (a skin cancer)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist
