Acneiform eruption

An acneiform eruption is a skin condition characterized by the sudden appearance of papules and pustules that resemble acne vulgaris. These eruptions can be caused by a variety of factors, including medications, infections, and systemic diseases. Unlike typical acne, acneiform eruptions may not be associated with comedones (blackheads and whiteheads).

Causes

Acneiform eruptions can be triggered by several factors:

• Medications: Certain drugs, such as corticosteroids, lithium, and some anti-epileptic medications, can induce acneiform eruptions.
• Infections: Bacterial infections, such as those caused by Staphylococcus aureus, can lead to acne-like lesions.
• Systemic diseases: Conditions like tuberous sclerosis and Beh√ßet's disease can present with acneiform eruptions.
• Environmental factors: Exposure to certain chemicals or occupational hazards may also result in acneiform eruptions.

Clinical Features

Acneiform eruptions typically present with:

• Papules and pustules that resemble acne lesions.
• Absence of comedones, which distinguishes them from acne vulgaris.
• Lesions that may appear on the face, chest, and back.
• Possible association with systemic symptoms, depending on the underlying cause.

Diagnosis

The diagnosis of acneiform eruptions involves:

• Clinical examination of the skin lesions.
• Detailed patient history to identify potential triggers, such as recent medication use or systemic symptoms.
• Laboratory tests or skin biopsy may be necessary to rule out other conditions or confirm the diagnosis.

Treatment

Treatment of acneiform eruptions depends on the underlying cause:

• Discontinuation or substitution of the offending medication, if applicable.
• Topical or systemic antibiotics may be used to treat bacterial infections.
• Management of the underlying systemic disease, if present.
• Use of topical retinoids or benzoyl peroxide to reduce inflammation and promote healing.

Prognosis

The prognosis for acneiform eruptions varies depending on the cause. Drug-induced eruptions often resolve after discontinuation of the offending agent. In cases related to systemic diseases, management of the underlying condition is crucial for resolution of the skin lesions.
