Abstract:
A 73-year-old woman evidencing an abnormal shadow on chest X-ray film since 1993 was admitted after a tumor of the left 8th rib was diagnosed in 2001. Computed tomography showed a low-density mass with coarse calcification arising from the left 8th rib and protruding into the abdominal cavity. The tumor was diagnosed as low-grade chondrosarcoma by incision biopsy and was resected together with the left 7th, 8th, and 9th ribs. The chest wall was reconstructed using Marlex mesh. Histological findings were compatible with Grade I chondrosarcoma. The patient had a long clinical course without distant metastasis thanks to the tumor's low malignancy.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
