Pityriasis Rosea Variant: Persistent Pityriasis Rosea in a 78-Year-Old Female Patient

Pityriasis rosea (PR) is a papulosquamous dermatosis seen most commonly in children and young adults. Variants of PR occur in 1 in 5 cases and can significantly impact a patient's quality of life. We present a case of a 78-year-old woman who developed a pruritic, erythematous rash consisting of annular patches on her face, bilateral arms and legs, and vulva. After months of persistent, progressive symptoms, she was diagnosed with persistent pityriasis rosea (PPR), a rare variant of PR. This case highlights the importance of recognizing variants of PR to allow for timely diagnosis and avoidance of over- or under-treatment.
