This case report detailed a 17-year-old boy with atypical juvenile pityriasis rubra pilaris (PRP) type 5, a rare inflammatory skin condition, which was diagnosed late despite symptoms starting at age 7. The disease, characterized by itchy, photoaggravated skin lesions covering the entire body, was confirmed through a skin biopsy showing hyperkeratosis and lymphocytic infiltrates. Treatment involved isotretinoin and regular monitoring. PRP type 5 is often misdiagnosed, highlighting the need for thorough clinical and pathological evaluation, and genetic testing for CARD14 mutations is advised due to possible familial connections.
