To assist in symptom differentiation, clinical presentations across the six most prevalent lip lesions show marked variations in etiology, transmissibility, and intervention:
| Clinical Condition | Visual & Sensory Characteristics | Contagious? | Standard Management |
|---|---|---|---|
| Fordyce Spots | Uniform 1, 2 mm yellowish-white granules; painless; visible on stretching. | No | No treatment needed; optional pulse dye or CO2 laser for cosmetic removal. |
| Cold Sores (HSV-1) | Tingling prodrome; clustered fluid-filled blisters that rupture and crust over. | Highly Contagious | Oral antivirals (valacyclovir) within 48 hours; topical docosanol. |
| Milia | Hard, solitary, pearly white keratin domes; no central pore; non-tender. | No | In-office sterile lancing; gentle topical retinoids (avoiding lip interior). |
| Comedones (Acne) | Single raised whitehead on facial hair edge; mild inflammation; central plug. | No | Targeted spot treatments; non-comedogenic balms; warm compresses. |
| Oral Thrush | Creamy white cottage-cheese plaques; raw, red, bleeding surface when scraped. | Low (Opportunistic) | Prescription oral antifungal suspensions (nystatin) or oral fluconazole. |
| Mucous Retention Cyst | Smooth, soft, fluid-filled nodule on inner lip mucosa; bluish to pale hue. | No | Surgical excision, cryotherapy, or marsupialization if persistent. |
