The conformity between dermoscopy imaging and Wood’s lamp diagnostic on periorbital hyperpigmentation

Abstract

Introduction: Periorbital hyperpigmentation (POH) is a common skin problem characterized by homogeneous/dark brown hyperchromic/pigmented macules around the lower eyelid and upper eyelid up to the malar area temporal area and the sides of the nose. POH is a multifactorial condition caused by both endogenous factors and exogenous factors, without one aspect dominating. Dermoscopy and Wood's lamp can assist the diagnosis of POH types when the inspection is regarded as weak. The assessment of the suitability of the dermoscopic image and Woods’ lamp diagnosis indicates an alternative supporting test in POH diagnosis. This study aimed to examine the conformity between dermoscopic images and Wood's lamp examination in POH diagnosis.Methods: This observational conformity study was conducted using a cross-sectional design. There were 38 subjects diagnosed with POH who went to the Cosmetics Division of Dermatology and Venereology, Universitas Sumatra Utara Hospital participated as subjects. Assessments regarded the types of POH analyzed based on dermoscopic images and Wood's lamp examination. Data analysed with SPSS version 20 using Kappa test.Results: On dermoscopy examination, the mixed type was the type most obtained, as many as 18 subjects (47,4%), whilst on Wood's lamp examination, the most dominant type obtained was pigment type, as much as 21 subjects (55,3%). Moderate conformity value on POH examination was obtained with dermoscopy and Wood’s lamp.Conclusion: Dermoscopic images and Wood's lamp examination shared a sufficient conformity value in POH diagnosis.
