Area of Science:

• Dermatology
• Allergy and Immunology
• Pediatrics

Background:

• Dermatology training must equip physicians to identify skin changes in diverse populations.
• Interpreting patch tests for contact dermatitis in skin of color is challenging due to the need to visualize erythema.
• A lack of clinical images of skin of color in medical literature hinders training.

Purpose of the Study:

• To provide visual examples of patch test interpretations in pediatric patients with skin of color.
• To demonstrate an effective approach for clinical interpretation of patch testing in melanin-rich skin.
• To address the gap in educational resources for dermatologists regarding patch testing in diverse skin tones.

Main Methods:

• Case study presentation of two pediatric patients.
• Inclusion of clinical photographs illustrating patch test reactions.
• Focus on the interpretation of positive patch tests in skin of color.

Main Results:

• Demonstrated visible erythema in patch test sites on pediatric patients with skin of color.
• Provided clear visual references for identifying a 1+ positive patch test reaction.
• Highlighted the importance of considering skin tone when assessing patch test results.

Conclusions:

• Physicians need enhanced training for patch testing in skin of color.
• Clinical images are crucial for accurate interpretation of patch test results in melanin-rich skin.
• This resource aids dermatologists in diagnosing contact dermatitis in pediatric patients of all skin tones.
