Medical Care

Improvement of pityriasis rotunda has been noted with 0.1% tretinoin cream, 10% lactic acid lotion, and 5% salicylic acid ointment; however, there is no effective local therapy and the pityriasis rotunda lesions usually are resistant to treatment.^[42]Improvement with treatment of the underlying disease has also been noted. The condition is difficult to treat and current treatments are often poorly efficient, with resolution sometimes taking months or years.^[10]
