Abstract
BACKGROUND

Synovial chondromatosis (SC) is a rare benign lesion first reported by Ambrose Pare in 1558. It is most common in the knee joint, followed by the hip joint and elbow joint. It is characterized by the presence of multiple pearl-like osteochondral bodies in the joint. The incidence in children is extremely low.

CASE SUMMARY

We report a 6-year-old Chinese boy who presented to our hospital with left hip joint pain and claudication for more than one year. We performed total surgical resection of SC tissue in the left hip. A good prognosis was confirmed at the 6-wk follow-up. Pain and swelling symptoms were totally relieved, range of motion of his left hip returned to normal, and there was no clinical evidence of lesion recurrence at last follow-up. Our case is the youngest reported patient with SC occurring in the hip.

CONCLUSION

SC is a rare disease and can be easily misdiagnosed. When we encounter children with hip pain and claudication, increased vigilance and a comprehensive physical examination and imaging examination should be considered, in order to avoid misdiagnosis and delayed treatment in patients.
