Abstract

Lipoma arborescens is a benign intra-articular tumor characterized by joint effusions, pain, and reduced range of motion. It is rare in adults and children. We present a case of lipoma arborescens in a 16-year-old male. The work up involved plain radiographs, MRI, incisional biopsy, and laboratory analysis.

Keywords: benign; intra‐articular; lipoma arborescens; tumor.
