title: Vascular malformation in the infrapatellar (Hoffa's) fat pad.
abstract: A 16-year-old girl presented with pain and swelling of her right knee for 2 years. Magnetic resonance imaging disclosed a mass in the infrapatellar fat pad. Arthroscopic removal of the lesion led to a histopathologic diagnosis of vascular malformation, which has not been reported exclusively in this location.
