Dermoscopic Study of Palmoplantar Dermatoses in a Tertiary Care Centre

Abstract

Introduction: Dermoscopy is a non-invasive diagnostic tool that enhances visualization of subsurface skin structures not visible to the naked eye. It improves diagnostic accuracy in dermatology, particularly in palmoplantar dermatoses, where clinical features are often atypical due to unique anatomical characteristics. Dermoscopy helps identify vascular patterns, scaling, adnexal changes, and disease-specific features, thereby supporting a systematic diagnostic approach and reducing unnecessary biopsies.

Aim & Objective: To evaluate various palmoplantar dermatoses using dermoscopy in a tertiary care center, to classify these conditions based on their dermoscopic features, and to provide an updated overview of the dermoscopic patterns seen in common palmoplantar dermatoses.

Materials & Methods: This 18-month descriptive observational study was conducted in the Department of Dermatology, Venereology and Leprosy at F.H. Medical College, Agra. Patients with clinically diagnosed palmoplantar dermatoses were included after informed consent. Detailed history, clinical examination, and dermoscopic evaluation using a handheld dermatoscope were performed. Dermoscopic parameters such as vascular patterns, scaling, follicular changes, and specific diagnostic clues were assessed and correlated with clinical diagnoses.

Results: The study included patients aged 3 to 73 years. Dermoscopy revealed distinct and reproducible patterns across various palmoplantar dermatoses, aiding differentiation of clinically similar conditions. It improved diagnostic confidence and reduced the need for invasive procedures while assisting in biopsy site selection and treatment monitoring.

Conclusion: Dermoscopy is a valuable adjunct in the evaluation of palmoplantar dermatoses, improving diagnostic accuracy, guiding biopsy decisions, and monitoring therapeutic response when correlated with clinical findings.
