Diagnosis: Angular cheilitis
A 45-year-old female presents with painful, macerated fissures at both corners of her mouth lasting for two weeks. She reports that the lesions are exacerbated by moisture and difficulty eating. Upon examination, erythema and crusting are noted at the labial commissures, leading to a consideration of underlying etiologies and management options.
A 45-year-old female presents with painful, macerated fissures at both corners of her mouth that have persisted for two weeks. She reports increased discomfort while eating and drinking, especially acidic foods. On examination, the lesions demonstrate significant erythema and crusting at the labial commissures.Location: Bilateral fissures at the corners of the mouth.Appearance: Erythematous, moist, and fissured lesions.Symptoms: Pain and tenderness, especially with movement.Exacerbating factors: Moisture from saliva and food.Associated findings: Possible candidal involvement noted on examination.
The lesions began approximately two weeks prior to presentation, with the patient noting that they worsened after eating and drinking. She has a history of dry mouth due to a medication for hypertension, which may contribute to her symptoms. The patient has not tried any topical treatments prior to this visit. She has no significant past medical history and denies any known allergies.Onset: Symptoms began two weeks ago.Triggers: Increased moisture during meals.Prior treatments: No prior topical treatments attempted.Medical history: History of dry mouth secondary to antihypertensive medication.Social history: Non-smoker, no recent travel.Family history: No significant dermatologic conditions reported.
Acute / First-Line ManagementTopical antifungal therapy, such as clotrimazole 1% cream applied twice daily until resolution.Topical corticosteroids, such as hydrocortisone 1% cream applied twice daily to reduce inflammation.Maintain dry conditions by using absorbent barrier creams, such as zinc oxide ointment, applied after meals.Workup and Diagnostic ConfirmationClinical diagnosis based on history and examination findings.Consider swabs for fungal culture if candidal infection is suspected.Patch testing may be warranted if an allergic contact dermatitis is suspected.Long-Term ManagementEducate the patient on maintaining oral hygiene and avoiding excessive moisture.Consider adjusting medications that may contribute to xerostomia.Follow up in 2-4 weeks to reassess and modify treatment if necessary.
Candidiasis: Often presents with similar fissures and can be confirmed with KOH preparation showing yeast forms.Contact dermatitis: May cause localized irritation and fissures; history of exposure to irritants or allergens can aid in differentiation.Angular stomatitis: Commonly associated with nutritional deficiencies (e.g., iron, B vitamins); may require dietary assessment.Herpes simplex virus infection: Can present with vesicular lesions and crusting; viral culture or PCR can confirm.Actinic cheilitis: Chronic sun damage may lead to fissuring and scaling, particularly in fair-skinned individuals; history of sun exposure is key.Systemic lupus erythematosus: Can cause angular lesions; consider if there are systemic symptoms or other skin findings.Behçet's disease: May present with recurrent oral ulcers and angular lesions; consider in patients with other systemic symptoms.Impetigo: Can cause crusted lesions; often associated with bacterial infection and requires culture for confirmation.
High-Yield PearlsMoisture management: Keeping the affected area dry is crucial in preventing exacerbation of angular cheilitis.Topical therapy: Antifungal creams are often effective, especially if candidal infection is suspected.Medication review: Evaluate medications that may contribute to xerostomia, potentially exacerbating the condition.Nutrition: Assess dietary intake for deficiencies that may predispose to angular lesions.Follow-up: Regular reassessment is necessary to monitor treatment efficacy and adjust as needed.Understanding the multifactorial nature of angular fissures is key to effective management.
