Oral Lesions in Pityriasis Rosea

Abstract

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.

Geographic tonguelike presentation in a child with pityriasis rosea: Case report and review of oral manifestations of pityriasis rosea

“…Less common presentations included tonsillar erythema and white annular plaques, seen in one patient each . Our analysis was similar to the one performed by Kay and colleagues, which showed that the two most frequently reported morphologies were punctate hemorrhages and erosions . In most reported cases, oral lesions resolved simultaneously with resolution of skin lesions within a few weeks.…”

“…Petechiae (62%) and each. 16 Our analysis was similar to the one performed by Kay and colleagues, 3 which showed that the two most frequently reported…”

“…Diagnosis is generally made based on the typical clinical findings, but some patients may present with atypical features, 2 including oral lesions, which are uncommon in patients with PR. 1,3 We report a case of a child with PR who was found to have geographic tonguelike lesions and review the literature on the oral manifestations of PR.…”

Pityriasis rosea: An important papulosquamous disorder

“…In our experience oral involvement is uncommon; its incidence varies in different studies from extremely low to approximately 16% 77,78 . Punctate hemorrhages, ulcerations, erythematous macules, vesicles, bulla, and erythematous plaques of the oral mucosa have all been observed 77,79 .…”

Pityriasis rosea: An update with a critical appraisal of its possible herpesviral etiology

“…5 Vidimos and Camisa, 25 however, found that 8 of 50 Caucasian patients (16%) had various asymptomatic oral lesions. According to Kay et al, 26 oral lesions can be categorized into 5 groups: punctuate hemorrhages, erosions or ulcerations (which are the most frequent), erythematous macules, erythematous annular lesions, and erythematous plaques. Bullous lesions have been described as well.…”
