A painful lump on a teenager's toe is a benign enchondroma

A 16-year-old girl attended our outpatient clinic complaining about a hard lump on the second toe of her left foot. She said it had been present for 6 years, but that in the past 3 months it had become moderately painful and that the pain was aggravated by walking. She said that the lump had not increased in size. She reported no history of trauma and no relevant medical history.
