Comments: A benign bony proliferative process typically identified in early adulthood but sometimes becoming symptomatic only later in adult life when there is pain and limitation of joint movement secondary to bony encroachment. Additionally, there may be adjacent soft tissue inflammation as in this case which is precipitating an iliotibial band friction type syndrome. There is a typical candle wax cortical thickening and trabecular condensation in a sclerotomal (distribution of the skeleton supplied by a sensory nerve) distribution. In approximately one quarter of the cases, soft tissue masses with calcification are seen.
