Oral Lesions in Pityriasis Rosea

Oral lesions are not commonly reported with pityriasis rosea (PR). We encountered a patient with clinical and histologic evidence of PR who developed aphthous ulcer-like oral lesions on the buccal mucosa, palate, and tongue. The oral lesions resolved concomitantly with the patient's skin lesions. The previous literature reports a wide variety of oral lesions in association with PR, but few dermatologists, to our knowledge, are aware of such an occurrence.
