ABSTRACT
Pityriasis rotunda is an uncommon dermatosis chacracterized by multiple, widely distributed, strikingly circular hypopigmented or hyperpigmented patches that are slightly scaly. Pityriasis rotunda has been associated with certain infective or malignant systemic diseases. No specific and effective treatment is available. A 27-year-old woman afflicted with multiple lesions of pityriasis rotunda on her back, buttock, abdomen and thighs without any local symptoms was treated with topical 20% urea and 0.025% tretinoin twice a day for 1 month. Complete remission with exellent cosmetic result was observed 30 days after this treatment. No recurrence was observed after 2 months later following commencement of treatment. Topical urea and tretinoin can thus be recommended as a practicable approach to the treatment of pityriasis rotunda.
