Cheilitis: Signs and Symptoms
Cheilitis presents with dryness, erythema, scaling, and cracking of the lips, often accompanied by desquamation, chapping, and pruritus, with clinical presentation varying by etiology and chronicity.
Primary Clinical Manifestations
The hallmark signs and symptoms of cheilitis include:
Acute Presentation
- Erythema (redness) of the vermilion border
- Erosions or superficial breaks in the lip surface
- Stinging or burning sensation 1
- Rapid onset of inflammation
Chronic Presentation
- Desquamation (peeling/scaling) - present in 90.8% of chronic cases 2
- Chapping (fissuring and cracking) - affects 74.3% of patients 2
- Pruritus (itching) - reported in 58.7% of cases 2
- Dryness of the lips - extremely common 3, 2
- Often asymptomatic in mild cases 1
Specific Variant Presentations
Drug-Induced Cheilitis (Retinoids)
When caused by medications like acitretin, cheilitis manifests as:
- Severe lip dryness - the most frequent side effect 3
- Requires application of fatty ointments for relief
- May progress to dry mouth and thirst 3
- Can include taste disturbances 3
Atopic Cheilitis
More severe presentation with:
- Impaired lip joining and mouth closure
- Associated with disordered nasal breathing 4
- More severe course when associated with disseminated neurodermatitis 4
Kawasaki Disease-Associated
Distinctive features include:
- Erythema and cracking of lips 5
- Bleeding lips from severe fissuring 5
- "Strawberry tongue" with prominent fungiform papillae 5
- Diffuse oropharyngeal erythema 5
Angular Cheilitis
Localized to mouth corners:
- Bilateral lesions at the angles of the mouth 1
- Often related to moisture, fungal/bacterial infection 6
Physical Examination Findings
Lip Barrier Dysfunction
Objective measurements in chronic cheilitis demonstrate:
- Elevated transepidermal water loss (TEWL) - significantly higher than controls 2
- Decreased skin capacitance - indicating impaired barrier function 2
Associated Features
- Swelling (edema) of lips - particularly in granulomatous variants 6
- Wickham's striae - white lines visible on dermoscopy in lichen planus cheilitis 7
- Erosions and ulcerations - in severe or erosive variants 6
- Crusting - especially in infectious or severe inflammatory cases 6
Distribution Patterns
- Typically affects the vermilion border (red portion of lips) 1
- Lower lip more commonly affected than upper lip 7
- May be unilateral or bilateral depending on etiology
- Can extend to perioral skin in severe cases
Common Pitfalls
Do not confuse cheilitis with:
- Oral mucositis (involves intraoral mucosa, not just vermilion) 8
- Angular cheilitis alone (localized to corners only) 1
- Actinic cheilitis (a potentially malignant condition requiring biopsy) 9, 10
Key distinguishing feature: True cheilitis is limited to the vermilion border of the lips, whereas conditions like oral mucositis extend into the oral cavity with erosions, ulcerations, and pseudomembranes affecting buccal mucosa, tongue, and palate 8.
Functional Impact
Patients commonly experience:
- Difficulty eating due to pain and cracking
- Sensitivity to temperature and spicy foods
- Cosmetic concerns from visible inflammation
- Performance limitations in activities requiring lip contact (e.g., brass musicians) 11
The severity ranges from mild discomfort with minimal visible changes to severe erosive disease with significant functional impairment and quality of life impact 2, 6.
