PERIOSTEAL CHONDROMA DEVELOPING IN A RIB AT THE SIDE OF A CHEST-WALL WOUND FROM A PREVIOUS THORACOTOMY - REPORT OF A CASE

We describe herein the case of a 45-year-old man who developed a perio steal chondroma in a rib at the site of a thoracotomy that had been pe rformed 24 years previously, To our knowledge, this is only the third case of a periosteal chondroma in a rib to be documented in the world literature. Some authors have suggested that trauma, including that of surgery, may induce chondroma formation and this association could ha ve been an important contributing factor in the induction of the tumor in this patient.
