Lipoma arborescens, or diffuse articular lipomatosis, is a rare intra-articular benign lesion of unknown etiology. According to the World Health Organization, it is classified as a tumorlike condition. The most common location of this lesion is the knee, where it usually affects the suprapatellar pouch. Reports of other locations of the lesion, including the ankle, hip, shoulder, wrist, or elbow, can be found in the literature1-8. Lipoma arborescens most frequently affects one joint. However, bilateral and multifocal joint involvement have been reported, with most of the reports involving the knee9-13. Histologically, it represents a hyperplastic condition in which proliferation of the synovial membrane and diffuse replacement of the subsynovial tissue by mature fat cells is observed. Therefore, it results in formation of villous projections that occupy the joint. We present the case of a young woman with lipoma arborescens in the knee joint, which was treated with arthroscopic synovectomy. She was informed that data concerning her case would be submitted for publication, and she provided consent.
