Giant chondromas arising from the ribs. A report of four cases

Chondromas may arise from the ribs but seldom grow to giant size. In a series of twenty-one cases, four giant tumours were encountered. Three were treated by excision without leaving a significant defect of the chest wall or impairment of respiration; the fourth was examined by biopsy. No evidence of malignant change was discovered in these four large tumours.
