title: Enchondroma protuberans of the rib.
abstract: Enchondroma protuberans of the rib may be indistinguishable from osteochondroma or chondrosarcoma. The problems of needle biopsy and the confusion which arose in the preoperative and intraoperative evaluation of two previous cases from the literature were avoided in the present case by total resection of the lesion. Where possible, total resection is recommended for accurate diagnosis.
