What Is Granulomatous Cheilitis?

The lips may become repeatedly or continuously swollen, firm, dry, cracked, or uneven. One lip or both lips can be affected, and swelling may come and go. Granulomas are collections of immune cells seen in inflamed tissue; their presence does not identify one single cause. A clinician may ask about dental products, cosmetics, foods, medicines, bowel symptoms, facial swelling, and symptoms elsewhere in the body. Examination and sometimes a biopsy help distinguish granulomatous cheilitis from allergic or irritant lip dermatitis, infection, and other inflammatory conditions.

Use a bland, fragrance-free barrier and avoid licking, biting, peeling, and fragranced lip products. Pause new cosmetics, toothpaste, or mouth products if they appeared around the time symptoms began, and keep a simple record of exposures and flare-ups. [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) can support the lip barrier. A clinician may also prescribe [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) for selected inflammation; do not use steroid creams on the lips without specific instructions about product, amount, and duration.

Seek urgent help if lip swelling comes with tongue or throat swelling, wheezing, trouble breathing, faintness, or difficulty swallowing. Arrange medical review for persistent swelling, painful cracks, pus, crusting, spreading redness, fever, or difficulty eating, drinking, speaking, or closing the mouth. Prompt assessment is also sensible when swelling keeps returning without an obvious trigger.

What could be contributing to my lip swelling? Should I stop any dental or cosmetic products? Do I need patch testing, blood tests, or a biopsy? Which barrier product is suitable, and how should prescribed treatment be used safely?
