Abstract
BACKGROUND: Hesitancy to perform skin biopsies in children or adolescents may lead to delayed diagnosis or misdiagnosis and relatively, few studies analyzing pediatric skin biopsies exist. AIM AND OBJECTIVES: This study aims to analyze the spectrum of skin diseases biopsied and demographic data of pediatric patients underwent skin biopsies at a tertiary health care center in India. MATERIALS AND METHODS: Biopsy records over six years were analyzed, noting demographic data, disease duration, clinical differential diagnoses (CDD), final diagnosis after histopathology, disease categorization, and agreement between clinical and final diagnosis. The mean, range, and statistical significance of differences between proportions were calculated. RESULTS: A total of 1308 biopsy records were analyzed. A male preponderance was noted (males - 55.1%; n = 721, females - 44.9%; n = 587). Most biopsies were performed in adolescents (12-18 years; 55.2%) followed by school-age children (5-12 years; 31.4%). Preponderant disease groups biopsied comprised papulosquamous (17.7%; n = 231) and infectious diseases (14.1%; n = 184). Leprosy was the most common infectious disease (37.5%; n = 69) with most patients belonging to borderline tuberculoid spectrum. The overall diagnostic agreement was 74.7%. No correlation of final diagnosis was noted with the number of CDD offered. In more than a fifth of cases, biopsy averted misdiagnosis. CONCLUSIONS: This study highlights the importance of skin biopsies in pediatric patients and the relatively high clinico-histopathologic agreement. Leprosy and papulosquamous diseases were preponderant in the pediatric dermatopathology caseload.
