Case Report: Treating Nose Lesions Caused by Staphylococcus Aureus and Acne

Aug 27

At Village Dermatology in Katy and Houston, Texas, we often evaluate patients with skin lesions that appear suddenly and persist for weeks to months. Some lesions are due to common skin conditions such as acne, while others are triggered by bacterial infections like Staphylococcus aureus (Staph).

Patient Case Overview

A 42-year-old male presented with red, inflamed lesions on his nose that had been present for several months. The breakouts were not painful but had worsened in appearance, prompting him to seek treatment.

During his evaluation, a dermatoscope exam revealed small inflamed papules consistent with a Staphylococcus aureus skin infection, as well as concurrent acne-related breakouts.

Staphylococcus Aureus Skin Infections

Staphylococcus aureus (Staph) is a common bacteria that lives on the skin. In some cases, it can cause infections when it enters through minor cuts, hair follicles, or inflamed pores. These infections may appear as:

Red, inflamed bumps
Pustules or small boils
Localized irritation and swelling

Some strains, such as MRSA (Methicillin-resistant Staph aureus), require stronger oral antibiotics. However, in most mild cases, topical treatments can resolve the infection.

Treatment Plan for Staph Lesions:

Benzoyl peroxide washes to reduce bacterial load.
Mupirocin ointment applied three times daily for 10 days.
Skin hygiene counseling to prevent reinfection.

The patient was also counseled on MRSA awareness, as nasal carriers can sometimes harbor resistant strains.

Coexisting Acne

In addition to Staph infection, the patient also had acne with inflammatory papules, pustules, and comedones. Acne in this setting may worsen due to bacterial overgrowth and skin inflammation.

Acne Treatment Plan:

Clindamycin 1% + Benzoyl Peroxide 5% topical gel, applied once daily.
Daily use of non-comedogenic cleansers and moisturizers.
Broad-spectrum SPF 30+ sunscreen to prevent hyperpigmentation and sun damage.
Education that improvement may take 2–3 months, with expectations of 60–80% reduction in acne lesions.

Why Dermatology Expertise Matters

This case demonstrates how skin infections and acne can overlap, making accurate diagnosis critical. Without proper treatment, Staph infections may worsen or spread, while untreated acne can lead to scarring and long-term skin damage.

Takeaway

Nose lesions may look like simple acne but can sometimes represent a Staph aureus infection. Proper diagnosis and targeted treatment are essential for effective healing.
