Oral Lesions in Pityriasis Rosea

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

“…The oral mucosa is considered an atypical site of involvement that is rarely reported in patients with PR. Features of reported PR cases with oral lesions are summarized in Table . Oral lesions appear to be more common in children than adults with PR .…”

“…Features of reported PR cases with oral lesions are summarized in Table 1. [7][8][9][10][11][12][13][14] Oral lesions appear to be more common in children than adults with PR. 5,15,16 In a study of 31 Caucasian children with PR, 11 (35%) had oropharyngeal lesions.…”

Unique clinical presentations of pityriasis rosea: aphthous ulcers, vesicles and inverse distribution of lesions

“…Although some state that the aphthae could be a separate entity from PR, the lesions tend to erupt and resolve at the same time as the PR lesions, supporting their single etiology when co-occurring [33]. The aphthae, appearing as shallow ulcers with a red rim in the buccal mucosa or soft palate, can be sore or asymptomatic [31,[33][34][35].…”

“…Costello observed a young boy with typical manifestations of PR along with a superficial, erythematous lesion on the mucosa, and a rectal temperature of 101.2oF [37]. Rosenbaum reported a man presenting with eruptions on the trunk and inguinal area with hemorrhagic lesions on the soft palate that increased in size up to 7mm and eventually resolved a few days after the cutaneous lesions [38]. Kestel described an 18-year-old man with biopsy-proven PR and ulcerative and hemorrhage lesions on the buccal mucosa [31].…”
