Clinical study of linear dermatoses and their histopathological correlation in a tertiary care hospital

Abstract

Objective To analyze the clinical presentation of various linear dermatoses and establish their correlation with histopathology at the skin out-patient department of Karnataka Institute of Medical Sciences, Hubli, from January 2021 to June 2022.   Methods Comprehensive patient histories, encompassing family history and trauma, were collected. Clinical examinations led to provisional diagnoses. Biopsies were conducted for histopathological examination with patient consent. Additional investigations were performed if deemed necessary.   Results Out of 90 cases, Lichen striatus was the most prevalent presentation, followed by herpes zoster, linear verrucous epidermal nevus, and linear lichen planus. Among patients undergoing biopsies, a 100% clinico-pathological correlation was noted for linear verrucous epidermal nevus and nevus depigmentosus. Correlation rates were 95% for lichen striatus, 90% for lichen planus, and one case clinically diagnosed as nevus sebaceous exhibited linear verrucous epidermal nevus features on histopathology.   Conclusion This study underscores the pivotal role of histopathological correlation, which significantly influences management decisions. The distinct management approaches for various linear dermatoses reinforce the necessity of histopathological examination for accurate diagnoses and tailored treatments.
