Abstract

Objective To describe predominant dermoscopic patterns in common pigmented skin lesions in skin of colour. Methods It was an observational study carried out at department of dermatology unit-II, Mayo Hospital Lahore. A total of 44 patients (12 males, 32 females) with common pigmented skin lesions were enrolled and interviewed. Their clinical pictures were taken with iPhone 6 & clinical differentials or diagnosis was formulated by three examiners via mutual agreement. Dermoscopic pictures were taken at the same time with Firefly DE350® using both optical and digital magnification. Predominant patterns were described keeping in mind the internationally accepted terminology and criteria. Results Common pigmented skin lesions included seborrheic keratosis (SK), solar lentigo, freckles, blue nevi, melanocytic nevi, dysplastic nevi etc. Melanocytic nevi had pigmented network, aggregated or peripheral globules and various types of pigment. Predominant pattern of SKs was milia like cysts and comedo like openings, lentigo had light brown pseudo network with well-defined border, common nevi had comma shaped vessels with brownish pigmentation, however, dermal nevi exhibited structure of less blue in colour. Conclusion Dermoscopy is a valuable tool in differentiating common pigmented skin lesions and the patterns are similar to the white race with certain subtle differences.
