Chondromyxoid fibroma of the temporal bone: Case report and review of the literature.
Chondromyxoid fibroma. J Foot Ankle Surg 2008;47(2): 153-9.
Many intraosseous processes contain mucin (chondromyxoid fibroma
and chondrosarcoma, to name a few).
Brachyury staining was further performed in the following 2 categories: (1) 58 nonchordomatous tumors, which included 26 chondroid tumors (4 cases of grade I chondrosarcoma, 9 cases of grade II chondrosarcoma, 3 cases of grade III chondrosarcoma, 2 cases of chondromyxoid fibroma
, 1 chondroblastoma, 4 osteochondromas, and 2 cases of extraskeletal myxoid chondrosarcoma), 7 liposarcomas, 5 rhabdomyosarcomas, 4 pleomorphic adenomas, 4 mucoepidermoid carcinomas, 4 mucinous adenocarcinomas, 6 germ cell tumors, and 2 cases of renal cell carcinoma (Table 2); and (2) 7 unrelated miscellaneous tissues, which included normal cartilage derived from trachea (2 cases), articular surface (1 case), and testicular tissue (4 cases).
The matrix of chondromyxoid fibroma
may sometimes resemble chondroblastoma, and both lesions can contain numerous osteoclast-like giant cells.
Bone lesions uncommon in neonates have been reported under such designations as fibrous histiocytoma, chondromyxoid fibroma
, or ossifying fibroma.
INTRODUCTION: Chondromyxoid fibroma
is a rare benign primary tumor which usually affects the metaphyses of the long bones of the lower extremities in childhood and young adults and constitutes less than 1% of all primary bone tumors.
In the differential diagnosis chondromyxoid fibroma
, chondrosarcoma, chondroblastoma, enchondroma, nonossifying fibroma and aneurysmal bone cyst should be included (10).
