Introduction

Erythrasma is a common, yet often overlooked, skin infection caused by the bacterium Corynebacterium minutissimum. It typically presents as brown, scaly patches with well-defined borders in the skin folds and creases. Although erythrasma is easily treatable, it is essential for healthcare professionals to be familiar with its identification and management. This article highlights the importance of teaching students about erythrasma and offers guidance for incorporating this topic into dermatology education.

Why Teach About Erythrasma?

1. Prevalence: Erythrasma is a widespread condition that affects people of all ages and ethnic backgrounds. The prevalence increases with age and is more common in individuals with diabetes or compromised immunity.

2. Misdiagnosis: Due to its similar appearance to other skin conditions such as tinea cruris, intertrigo, or psoriasis, erythrasma can be easily misdiagnosed if not adequately considered.

3. Appropriate Treatment: When properly diagnosed, erythrasma is simple to treat with topical or oral antibiotics. Misdiagnosis can lead to unnecessary use of antifungal medications, causing delays in resolving the infection and potential issues related to antibiotic resistance.

Integrating Erythrasma into Dermatology Education

1. Visual Aids: Include photographs of erythrasma cases in educational materials and presentations, emphasizing differentiating factors from other skin conditions.

2. Clinical Scenarios: Incorporate case studies or roleplay scenarios that involve diagnosing erythrasma into classroom activities to encourage critical thinking and promote active learning.

3. Tips for Diagnosis: Teach students how to identify erythrasma using a Wood’s lamp, which causes the bacteria to emit coral-red fluorescence under ultraviolet light – a distinguishing feature of erythrasma.

4. Treatment Options: Discuss the most common treatment methods, including topical antibiotics (e.g., fusidic acid, erythromycin) and oral antibiotics (e.g., clarithromycin), as well as proper hygiene practices to prevent recurrence.

5. Comorbidities: Emphasize the increased risk of erythrasma in patients with diabetes or weakened immune systems, and explain why it is particularly essential to recognize and manage this condition in these populations.

Conclusion

Erythrasma is a common yet often misdiagnosed skin condition that merits a place in medical and nursing school curriculums. By incorporating discussions of erythrasma into dermatology education, students will be better prepared to identify, diagnose, and treat this bacterial infection effectively. An interdisciplinary approach to teaching about erythrasma can lead to improved patient care and ultimately help combat antibiotic resistance resulting from improper treatment.
