A huge osteoma of the 11th left rib had been present for over 50 years in a 71-year-old man. Operation had been recommended on many occasions but had been refused because the growth had caused the patient no discomfort. The roentgenographic appearance of the tumor suggested an osteoma which involved the rib and extended into the left pleural cavity above and retroperitoneally into the abdomen below. The histological nature of the tumor was confirmed when the patient died of hemorrhage due to cancer of the right kidney. This case is deemed worthy of report because of the unusually large size of the osteoma (3.5 lb.), its benign course, and the unusual appearance of the chest roentgenogram.
