Abstract
Pityriasis rubra pilaris (PRP) is a rare idiopathic papulosquamous inflammatory disorder. There are 6 distinct subtypes of PRP. Here we report a case with type II PRP. A 45-year-old male presented with 8 months history of recurrent very itchy skin lesions. Skin examination revealed multiple well defined scaly erythematous patches on his scalp, back and chest. A 4 mm punch kin biopsy shows hyperkeratosis, parakeratosis, thick and shortened rete redges. A diagnosis of pityriasis rubra pilaris type II was made. The Patient was started on acitretin 25 mg capsules once daily, topical betamethasone diprpionate 0.05% ointment once daily with excellent response.
