A cause of erroneous diagnosis of pigmented villonodular synovitis.
Abstract
An unusual type of benign vascular hamartoma, which shows a curious papillary organization of thrombus and abundant haemosiderin deposition, is liable to be misdiagnosed histologically as pigmented villonodular synovitis. Nine examples of this type of lesion are briefly presented and the differential diagnosis is discussed.
