Juvenile psoriatic arthritis.

Among 664 juvenile chronic arthritis patients cared for in the Outpatient Clinic of the Pediatric Rheumatology Unit of the National Institute of Rheumatology and Physiotherapy 11 were found with juvenile psoriatic arthritis, and their data regarding skin, joint, ophthalmological, laboratory and radiological manifestations were analysed. These patients were categorised according to the four subgroups suggested by Truckenbrodt et al. Considering that the occurrence of the disease is rare, the small number of patients investigated in this study can provide additional data to the study of Truckenbrodt. The higher number of patients with JPA thus studied can give more information for a multicentric evaluation.
