Isolated areas of hypopigmented skin can be a manifestation of mycosis fungoides. This is a rare clinical form with a particular clinical course and histology which has been described only in black subjects. Over a 10-year period, a 28-year-old woman from Mali developed non-infiltrated hypopigmented and discretely squamous macules involving the entire body. The diagnosis of mycosis fungoides was made on pathology evidence of epidermotropic lymphocyte infiltration with a few small nests. PUVA led to rapid regression of the lesions. Hypopigmented mycosis fungoides has been described in young black subjects (mean age 19 years). The diagnosis is usually made late because benign skin affection is usually the first diagnosis (pityriasis alba, pityriasis versicolor). The pathogenesis of these hypopigmented lesions is not known. PUVA appears to be effective in most cases.
