A study on histopathological and dermoscopic correlations in pityriasis versicolor

Pityriasis versicolor (PV) is a superficial mycoses caused by lipophilic fungus; Malassezia yeast. Dermoscopy can be used as complementary tool for assessing PV, but histopathology confirmatory, whenever results of KOH (potassium hydroxide) examination are inconclusive. There dearth Indian data on the findings dermoscopy and PV. To find correlation between dermoscopic histopathological features in versicolor. Fifty consecutive patients diagnosed with PV were recruited cross sectional study. mount skin scrapings from lesions was done positive all patients. using ILLUCO Dermoscope noted. Biopsy sent examination.
