Multifocal pigmented villonodular synovitis in a child.
Pigmented villonodular synovitis is a rare benign disorder and usually affects young and middle-aged adults. It occurs either as a localised pedunculated form or more common diffuse form, and is almost always unifocal. Only few cases of multifocal involvement have been reported, all of them in children. Multifocal pigmented villonodular synovitis occurring in a 5-year-old girl is presented. Both her knees and left elbow were involved. All three lesions were of localised pedunculated type and were completely excised. She is believed to be one of the youngest patients reported.
