Acute Knee Pain in a Child Due to Pigmented Villonodular Synovitis.

Abstract

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.
