“…Trichoscopy allows distinguishing between normal terminal hairs and vellus hairs, which are 0.03 mm or less in thickness and less than 3 mm in length. 16,17 Hence, we conclude that the higher number of hairs counted during the follow-up in our patient reflects HF neogenesis and does not reflect transformation of vellus hair to terminal hair under hormonal influence.…”

However, it is unlikely to miss them under magnification in digital phototrichogram (Fig. 1). Trichoscopy allows distinguishing between normal terminal hairs and vellus hairs, which are 0.03 mm or less in thickness and less than 3 mm in length. 16,17 Hence, we conclude that the higher number of hairs counted during the follow-up in our patient reflects HF neogenesis and does not reflect transformation of vellus hair to terminal hair under hormonal influence.

Background Leprosy is known to be a great mimicker. Its dermatoscopic evaluation may be of value in establishing diagnosis. Objective To study the dermatoscopic findings encountered across the leprosy spectrum. Methods This was a multi-centre cross-sectional study of leprosy patients, where after a thorough cutaneous and neurological evaluation, representative skin lesions from the study patients were photographed in standard settings, and the most representative skin lesions were chosen for dermatoscopic evaluation. Data was entered in a structured proforma and a descriptive analysis of dermatoscopic patterns was carried out. Results A total of 53 cases of ages between 14 and 80 years, ranging from tuberculoid to the lepromatous spectrum of disease, with active skin lesions in the form of patches and plaques were included. The spectrum of leprosy as per Ridley-Jopling classification at diagnosis was indeterminate in 1 (1.9%), tuberculoid in 1 (1.9%), borderline tuberculoid in 25 (21.5%), borderline lepromatous in 9 (17%), lepromatous in 14 (26.4%) and histoid in 3 (5.7%). Dermatoscopic features included distorted pigment network in 48 (90.6%), focal white areas in 40 (75.5%), reduced eccrine and follicular openings in 43 (81.1%), widened skin lines in 28 (52.8%), circle hairs in 15 (28.3%) and white shiny streaks in 17 (32.1%). Conclusion Dermatoscopy is a practical, non-invasive device to assess skin lesions of leprosy and provide cues to its diagnosis, spectral classification and differentiating it from other granulomatous disorders. However, dermatoscopy alone cannot reliably differentiate between the various types of leprosy and future large-scale studies are required. Limitations of the study The numbers for each subtype were variable and few in some spectrum of leprosy patients. A dermatoscopic-histologic correlation was not done.
