Truncal Acne: A Neglected Entity

Area of Science:

• Dermatology
• Acne Vulgaris Research

Background:

• Truncal acne (chest, back, shoulders) affects over 50% of acne patients.
• Limited research exists on truncal acne compared to facial acne.
• Underdiagnosis and undertreatment are common due to patient omission and physician focus on facial acne.

Purpose of the Study:

• To review current literature and recent recommendations for truncal acne management.
• To highlight the clinical characteristics and treatment considerations for truncal acne.

Main Methods:

• Literature review of available information on truncal acne.
• Analysis of treatment strategies for facial acne and their applicability to truncal acne.
• Consideration of specific challenges in truncal acne treatment.

Main Results:

• Truncal acne shares pathogenic similarities with facial acne, suggesting similar treatment approaches.
• Topical retinoids combined with antimicrobials are a logical first-line treatment.
• Oral isotretinoin is indicated for severe truncal acne.
• Unique considerations include lesion extent, antibiotic resistance risk, accessibility, and product staining.

Conclusions:

• Truncal acne requires greater research attention and clinical consideration.
• Early and effective treatment is crucial to prevent sequelae like scarring and pigmentary changes.
• Treatment strategies should account for the specific challenges of truncal acne management.
