  • Oral mucosal involvement in PRP is exceptionally rare, with only three prior documented cases in English literature.

Observation:

  • A case study of a 68-year-old male patient with pityriasis rubra pilaris is presented.
  • The patient exhibited involvement of the tongue and palate.

Findings:

  • This presentation represents the fourth reported case globally of pityriasis rubra pilaris with oral mucosal lesions.
  • The study discusses the clinical and histopathologic features of this rare manifestation.

Implications:

  • This case expands the understanding of pityriasis rubra pilaris's potential oral manifestations.
