Abstract

Dermatophytosis is common superficial mycosis with an increase in frequency, severity and relapse rates in recent years. Diagnosis of dermatophytosis is posing difficulties is diagnosis because of partial treatment and steroid abuse. Dermoscopy is an established non-invasive tool which has the potential to aid the clinical diagnosis of various dermatology Objective: The present study aims to study the dermoscopic findings of various dermatophytosis. Materials and Method: It was a cross sectional study conducted over a period of 18 months involving 300, KOH positive cases of dermatophytosis which were later evaluated using a dermoscope (Dermlite DL3) with a magnification of 10x. Results: Out of 300 cases, 217(72.33%) were male and 83 (27.67%) females with a male-to-female ratio of 2.6:1. The mean age in the present study was 26 ± 6.4 years. The most common type was tinea corporis (44.6%) followed by tinea cruris (19%). Common dermoscopic findings of tinea corporis and cruris were white scales in 191(63.6%) followed by red -brown globules in 141(47%) cases. The most frequent findings in Tinea capitis was comma shaped hair 21 (7%) followed by black dots in 11 (3.67% ). Onychomycosis showed chromonychia and spike pattern in 46 (15.33%) as the most common dermoscopic findings. Conclusion: Dermoscopy is a rapid, non-invasive in-vivo technique for diagnosis of tinea infection and may be useful in overcoming the shortcomings of conventional diagnostic methods.
