Case reportA 67-year-old male patient, a retired entrepreneur, was admitted to the OKD for the diagnosis and treatment of rapidly progressive erythematous papular skin rash. The first skin lesions, presenting as erythema on the face and palms, appeared approximately 2 weeks prior to hospitalisation.

In the literature, there are reports of cases where symptoms of infection preceded the onset of pityriasis rubra pilaris. Objective: Presentation of the case of a 67-year-old patient with type I pityriasis rubra pilaris to highlight the possible association between pityriasis rubra pilaris with infectious agents. Case report: A 67-year-old patient was referred to hospital because of rapidly progressive erythematous papular skin rash preceded by symptoms of an upper respiratory tract infection. On physical examination, attention was drawn to perifollicular papules covered with cap-like scales as well as confluent erythema and features of hyperkeratosis on the hands and feet. Based on the clinical presentation and histopathological findings, type I pityriasis rubra pilaris was diagnosed and treatment with acitretin was initiated. Conclusions: Infectious agents have the potential to be a trigger for pityriasis rubra pilaris. Acitretin continues to demonstrate efficacy in the treatment of pityriasis rubra pilaris.
