TLDR Dermoscopic features can help identify and differentiate types of pityriasis versicolor.
This cross-sectional observational study assessed dermoscopic features of pityriasis versicolor (PV) in 57 patients, revealing that nonuniform pigmentation was the most common finding in both hypopigmented (97.67%) and hyperpigmented (100%) lesions. Other significant features included scaling (93.02%), clearly demarcated borders (46.51%), and perilesional hyperpigmentation (34.88%). Hypopigmentation around hair follicles was notably present in hypopigmented lesions (55.81%). The study suggests that dermoscopy is a valuable diagnostic tool for PV, especially in atypical cases, and highlights "double-edged" scales as a unique dermoscopic feature of PV. Limitations include the small sample size and the cross-sectional design.
