title: Chondroma of the diaphragm mimicking a giant liver tumor with calcification: report of a case.
abstract: Extraskeletal chondroma is an unusual benign tumor, which rarely arises in the diaphragm. We report a case of chondroma of the diaphragm in a 31-year-old woman. Initially, a benign liver tumor with calcification was suspected, based on pre and intraoperative examination findings. Although parts of the tumor were contiguous with the diaphragm, its connections with the diaphragm were much narrower than its connection with the liver, which suggested a liver tumor. Pathological examination subsequently revealed that the chondroma was contiguous with the diaphragm and that there was a distinct border between the tumor and the liver; thus, the tumor was diagnosed as a chondroma of the diaphragm.
