Acne
Acne manifests through various types of skin lesions, including:
- Blackheads: Small, dark-colored bumps caused by clogged hair follicles.
- Whiteheads: Similar to blackheads but with a white or flesh-colored top.
- Papules: Small, red, tender bumps.
- Pustules: Papules with pus at their tips.
- Nodules: Large, painful lumps beneath the skin.
- Cysts: Deep, painful, pus-filled lumps that resemble boils and carry a high risk of scarring.
Acne typically appears on areas with a high density of oil glands, such as the face, forehead, chest, upper back, and shoulders.
Diagnosis
A healthcare provider diagnoses acne through a skin examination. During this exam, the provider looks for different types of acne lesions and assesses the severity of the condition. The severity of acne is often categorized as:
- Mild: Predominantly whiteheads and blackheads.
- Moderate: Multiple papules and pustules.
- Severe: Large, painful nodules and cysts.
No specific diagnostic tests are required for acne, but providers may consider additional tests if there is a sudden onset of severe acne, especially in adults, to rule out underlying conditions.
