Recognizing the Symptoms
Perioral dermatitis typically presents as small, inflamed bumps around the mouth, nose, or eyes. The skin immediately next to the lips is usually unaffected, which is a key feature in diagnosis. Patients may experience mild burning or stinging, but the condition often resolves without scarring.
Diagnostic Tests
A diagnosis of perioral dermatitis is usually made based on clinical examination and patient history. Skin biopsies are rarely needed but can help differentiate it from other conditions if necessary. Tests like potassium hydroxide (KOH) preparation can be used if a fungal infection is suspected.
Differential Diagnosis
Perioral dermatitis can be confused with other skin conditions like acne, rosacea, or seborrheic dermatitis. Each has distinct features, such as the presence of comedones in acne or telangiectasias in rosacea. Accurate differentiation is crucial for effective treatment.
