Acute Knee Pain in a Child Due to Pigmented Villonodular Synovitis
نویسندگان
چکیده
INTRODUCTION Pigmented villonodular synovitis (PVNS) is a proliferative condition of the synovium, which is composed of nodules and/or villi and has an abundant number of hemosiderin-laden macrophages. CASE REPORT A 10-year-old boy presented with an acute irritable knee. Emergency arthroscopy showed a nodular PVNS in the intercondylar notch. The symptoms resolved after resection of the lesion. CONCLUSION PVNS of the knee in children is a rare entity. It can be one of the causes of acute irritable knee. Complete resection of the nodular PVNS can cure the disease.

متن کاملPigmented Villonodular Synovitis Presenting as a Popliteal Cyst

As a result, the diagnosis may remain elusive, as the classic signs of tenderness and effusion are not specific. Occasionally, PVNS presents as a popliteal cyst, which may divert attention from intra-articular pathol...
