Abstract:We conducted a prospective study of 20 patients with pig. menting pityriasis alba (PPA) over a period of two years. Characteristic morphology revealed a central zone of bluish hyperpigmentation surrounded by a hypopigmented, slightly scaly halo of variable width. All patients displayed lesions on the face. Concomitant extrafacial Involvement was uncommon. A significant finding was an associated dermatophyte infection in 13 patients (65%). These patients all received griseoful‐vin 10 mg/kg/day for eight weeks, resulting In the resolution of PPA in seven within 4 to 20 weeks. These were also treated with 1% hydrocortt‐sone. Biopsy specimens from two patients showed similar features, namely, a subacute dermatitis with variable pigment Incontinence, lmmu‐nohistochemical labeling revealed a preponderance of T lymphocytes. Pigmenting pityrlasis alba seems to be a variant of classic pityriasis alba showing a strong association with dermatophyte infection, especially tines capitls. It may be related to Iichenoid melanoderma
