Differential Diagnosis for Multiple Papular Lesions at the Center of the Face
Single Most Likely Diagnosis
- Acne: This is the most common condition that presents with multiple papular lesions on the face, particularly in the central area. The lesions can range from comedones (blackheads and whiteheads) to inflammatory papules and pustules.
Other Likely Diagnoses
- Rosacea: Characterized by recurrent episodes of flushing, erythema, and papules or pustules, primarily on the central face. It's more common in adults and can be triggered by various factors including sun exposure, spicy food, and alcohol.
- Folliculitis: An inflammatory condition affecting the hair follicles, which can present with papular lesions. It can be caused by bacterial, viral, or fungal infections and is often seen in areas with high hair density, like the face.
- Keratosis Pilaris: Although more commonly found on the arms and legs, keratosis pilaris can occasionally present on the face, especially in children and young adults, with small, rough, sandpapery papules.
Do Not Miss Diagnoses
- Lupus Miliaris Faciei: A rare condition that can mimic acne or rosacea but is actually a form of cutaneous lupus. It presents with reddish-brown papules on the face and can be associated with systemic lupus erythematosus.
- Sarcoidosis: A systemic disease that can manifest with skin lesions, including papules, particularly on the face. It's crucial to diagnose because it can affect multiple organs.
- Tuberculosis (Lupus Vulgaris): A cutaneous form of tuberculosis that can present with papular lesions on the face, among other symptoms. It's essential to consider in endemic areas or in individuals with risk factors.
Rare Diagnoses
- Demodex Folliculitis: Caused by the Demodex mite, which can lead to follicular inflammation and papular lesions, particularly in immunocompromised patients or those with poor hygiene.
- Granuloma Faciale: A rare, chronic condition characterized by single or multiple, soft, brownish to purple plaques or papules, typically on the face. The cause is unknown, and it can be challenging to treat.
- Perioral Dermatitis: Presents with small, papular lesions around the mouth, which can extend to the central face. It's often associated with the use of topical corticosteroids, cosmetics, or dental products.
