Lipoma arborescens associated with osseous/chondroid differentiation in subdeltoid bursa

Abstract: Lipoma arborescens (LA) is a rare benign lesion of unknown etiology. It is characterized histologically by villous proliferation of the synovial membrane and diffuse replacement of the subsynovial tissue by mature fat cells. This condition affects the knee joint most commonly. Cases involving other locations including glenohumeral joint,[1] hip,[2] elbow,[3] hand[4] and ankle[5] have been rarely described. Involvement of the subdeltoid bursa has also been reported, but to date no case has described LA with oss… Show more

“…Current literature about LA is scarce and mainly consists in case reports. Interestingly, many of them have been published in the last years [ 7 , 8 ] although this entity was described over 50 years ago. [ 9 ] This may be due to an increased awareness about this disease and improvement in modern imaging techniques (MRI).…”

“…It is characterized by fatty infiltration of the subsynovial connective tissue. It is usually described in the knee (32,33) but may be observed in the hip (34), shoulder (35), wrist (36), or elbow (37). The disease is monoarticular in most cases but involvement of several joints in the same patient has been described (36,38,39).…”
