Early-onset gouty arthritis.

Five cases of early-onset gouty arthritis are presented, with roentgenographic abnormalities evident in the first two decades of life. Three patients suffered from "primary" gout; classification of the other two patients was difficlut because of associated mental retardation, hypothyroidism and psoriasis. Radiographic alterations included soft-tissue masses and calcification, with typical erosive abnormalities and predilection for the hands and feet. The sacroiliac joints were abnormal in two patients.
