The Dermoscopic Patterns in Common Pigmented Skin Lesions

Objective: To determine the dermoscopic patterns in common pigmented skin lesions.

Setting and duration Study: This study was conducted at Dermatology Department, Civil Hospital, Hyderabad, during October 18, 2020 to April 17, 2021.

Materials and Methods: After taking approval from hospital ethical committee and written informed consent from 150 patients, all patients with pigmented skin lesions were enrolled.

Results: Age range in this study was from 15 to 60 years with median (IQR) age was17 (15 -60) years and mean duration of disease was 5.67+ 2.14 months. Among the common pigmented skin lesions, 86 (57.4%) had sharp demarcation, 29 (19.3%) had Dots and gobules, 7 (4.5%) had Pseudonetwork, 12 (8%) had Homogenous structure less pigmentation, 78 (52%) had Milia-like cysts and 21 (14%) had Cerebriform pattern.
