Summary Patients with pityriasis versicolor require careful examination of the entire body surface, which should include the use of Wood's light. Otherwise, lesions may be overlooked and left as untreated foci of relapses. Twenty cases of uncommon locations of this mycosis were studied; Malassezia furfur was isolated from all 20 subjects. Forty‐one of the 99 lesions seen in our 20 patients could only be found with the use of Wood's light. Seventeen patients showed involvement of the scalp; in 11 of these cases the Wood's light was required. These scalp lesions were found either as isolated patches or as an apparent extension of lesions of the neighboring glabrous skin. The highest incidence was seen in the occipital region. Six patients had intertriginous lesions on the retroauricular fold and on the ear itself (posterior aspect, border and concha). One patient showed lesions in the superciliary region, which seems to be a location not previously observed. Less commonly, lesions were also found on the axillae, intergluteal fold, inguinocrural fold, penis, dorsum of hands, dorsum of fingers, groin (where they can be confused with erythrasma), and in the popliteal region.
