There is no specific treatment for pityriasis rotunda. People diagnosed with this condition usually need to undergo medical and physical examinations and have appropriate laboratory and radiographic tests to check for internal disease or malignancies. The lesions usually improve or resolve with treatment of the underlying internal disease or malignancy. Symptomatic treatment of lesions using topical retinoids, salicylic acid ointment, and lactic acid lotion has been used. However, the lesions can be resistant to therapy.
