ABSTRACT
Observations:
Pityriasis rubra pilaris (PRP) is a rare skin disease characterized by erythematous follicular papules and desquamation. Clinically follicular keratosis, perifollicular erythema, and palmoplantar hyperkeratosis are observed but erythroderma may occur rarely. PRP is one of the rare causes of erythroderma. We identified a PRP case that rapidly progressed to erythroderma in a 49-year-old male patient with no PRP diagnosis before. It is presented due to being a rare case of erythroderma.
