Blaschkoid pityriasis versicolor.
A 31-year-old male patient complained of having follicular and brownish red maculopapules along the Blaschko's lines on the right chest for 2 days. On examination, follicular brownish maculopapules were present on the chest with a uniform size of about 3 mm in diameter. The lesions were isolated without a tendency to merge, giving several S-shaped, band-like appearances. Direct mycological examination of the skin flakes revealed many pseudomycelial hyphae and yeast cells with typical spaghetti and meatball appearance. Wood's light examination of the lesion revealed a golden yellow fluorescence. A diagnosis of blaschkoid pityriasis versicolor was suggested because of blaschkoid distribution of the lesions in this new variant of PV.
