Abstract

Background: Atrophic scars are a common dermatologic condition. Although they rarely result in serious medical complications, their predominant facial distribution can lead to substantial aesthetic concerns and adverse psychological impacts. Objectives: To describe the clinical characteristics and classification of atrophic scars at Can Tho Hospital of Dermato-Venereology from 2025 to 2026. Materials and methods: A cross-sectional descriptive study was conducted on 56 patients with atrophic scars at Can Tho Hospital of Dermato-Venereology from April 2025 to February 2026. Results: The mean age of participants was 26.45 ± 7.15 years, with the 21-30-year age group accounting for the largest proportion (55.4%). Female patients predominated (58.9%). The mean age at scar onset was 18.54 ± 3.58 years. Acne vulgaris was the most common etiologic factor (83.9%). The cheeks were the most frequently affected anatomical site (45/56 patients). Boxcar scars were the predominant morphological subtype (87.5%), while mixed scar patterns were observed in 48.2% of patients. According to the qualitative Goodman and Baron scale, most patients had grade 4 atrophic scars (46.4%). More than 20 scars were present in 64.3% of patients. Age ≥30 years and scars caused by varicella or trauma were significantly associated with grade 4 atrophic scars (p = 0.024 and p = 0.008, respectively).  Conclusions: Atrophic scars were predominantly secondary to acne vulgaris and therefore occurred mainly in adolescents and young adults, boxcar scars represented the most common morphological subtype, and the cheeks were the most frequently involved anatomical site. Patients aged ≥ 30 years and those with atrophic scars secondary to varicella or trauma were more likely to have grade 4 scars than younger patients and those with acne-related atrophic scars.
