Nail changes can serve as indicators of trophic changes due to leprosy. To describe the onychoscopy findings in leprosy cases and to identify any specific findings in leprosy patients in comparison to controls. The first 30 leprosy patients and 30 age and sex-matched controls who attended our tertiary care center from 1 August 2018 were included in this cross-sectional study. Onychoscopy examination of all fingernails was performed at 50× magnification using dinolite dermoscope AM4113ZT under non-polarizing light to document surface changes and under polarizing light to document pigmentation and vascular changes. The observed nail changes in cases and controls were compared using Pearson's Chi-square test. Statistically significant association with leprosy was found for pitting, onycholysis, melanonychia, transverse lines, nail pallor, and onychauxis. Nail pallor was unique to leprosy patients. Small sample size and not evaluating toenails were the major limitations of the study. Studies with large sample size are needed to assess the significance of nail pallor as a specific onychoscopy finding in leprosy.

Alopecia areata (AA) is a chronic, non-scarring type of alopecia that presents as patchy hair loss over the scalp and other parts of the body. The diagnosis of AA can sometimes be challenging. Trichoscopy can be used to observe certain follicular patterns, shaft changes, and interfollicular pattern which help in diagnosing and determining the disease activity in AA. This study was a 1-year hospital-based observational cross-sectional study consisting of 60 patients clinically diagnosed
