Abstract
Pityriasis versicolor may present as hypopigmented, hyperpigmented, concomitantly hypo- and hyperpigmented, erythematous, and atrophic subtypes. We report a 15-year-old boy with pruritic greenish plaques on his anterior abdominal wall. Examination under Wood’s light and skin scrapings for KOH smear examination substantiated pityriasis versicolor. We found no extraneous cause for the greenish pigmentation. The eruptions and the discolouration subsided four weeks after systemic fluconazole treatment. We believe that this represents the first case of such presentation of pityriasis versicolor. The mechanism of the strange colouration is unknown.
