Circumscribed juvenile type pityriasis rubra pilaris (type 4): are we missing them?.
J Pak Assoc Derma Jan ;20(2):98-102.

Pityriasis rubra pilaris (PRP) is a rare disease. The lack of pathognomonic features and specific clinical or diagnostic features often make identification of PRP very difficult. PRP type 4 (circumscribed juvenile type) is characterized by scaly plaques on elbows, knees and palmoplantar keratoderma. Sometimes these lesions may become extremely difficult to differentiate from those of psoriasis. We report 3 cases of PRP type 4, noted in just 5 months. We feel PRP, specially the type 4, is not so rare in Indian subcontinent. A good clinical knowledge and high index of suspicion may help to identify more cases.
