Differential Diagnosis for Facial Eritema
Single Most Likely Diagnosis
- Rosacea: A common skin condition characterized by facial redness, often accompanied by small, pus-filled bumps. It's a likely diagnosis due to its prevalence and the fact that facial eritema is a hallmark symptom.
Other Likely Diagnoses
- Sunburn: Prolonged exposure to the sun can cause facial redness and eritema, making it a plausible diagnosis, especially in individuals who spend a lot of time outdoors.
- Contact Dermatitis: An allergic reaction or irritation from skin care products, makeup, or other substances can lead to facial redness and eritema.
- Acne: Inflammatory acne can cause redness and eritema on the face, particularly if the acne is severe or if the individual has a tendency to pick at their skin.
Do Not Miss Diagnoses
- Lupus: Systemic lupus erythematosus (SLE) can cause a characteristic "butterfly" rash on the face, which may be mistaken for simple eritema. Missing this diagnosis could have serious consequences due to the potential for organ damage.
- Dermatomyositis: An autoimmune condition that can cause skin rash and muscle weakness. Facial eritema can be a symptom, and missing this diagnosis could lead to delayed treatment and worsening of symptoms.
- Cellulitis: A bacterial skin infection that can cause redness, swelling, and warmth of the skin. If left untreated, it can lead to serious complications, such as abscesses or sepsis.
Rare Diagnoses
- Sarcoidosis: A condition that can cause granulomas to form on the skin, leading to facial eritema. It's a rare diagnosis, but one that should be considered if other causes have been ruled out.
- Erythromelalgia: A disorder that causes burning pain, heat, and redness in the hands and feet, but can also affect the face. It's a rare condition, but one that may be considered if other diagnoses have been excluded.
