Chondromyxoid fbroma (CMF) is a rare, benign tumor of the bone that represents fewer than $2\%$ of all benign tumors of bone. CMF is most often found in the long tubular bones, especially the tibia and femur near the knee joint. Less common sites included the pelvis, fibula, calcaneus and rib. A 54-year-old male patient presented to us with history of swelling and mild, intermittent local pain without any rise in overlying skin temperature in lateral portion of left 7th rib for one-month duration, which was diagnosed as benign rib tumor by plain chest X-ray and CT scan, and treated successfully by excision of rib with good result. Pathologic diagnosis of this tumor was CMF. Without any medical therapy, there was no evidence of recurrence after operation. We report this case and follow-up of the patient.

Giant cell tumor (GCT) of the rib may present as a posterior mediastinal mass when it involves the posterior arc. Only 4 cases of GCT of the rib presenting as a posterior mediastinal mass have been reported. We report a case of a 38-year-old man with GCT of the rib. Computed tomography revealed a well-defined, multi-lobulated, heterogeneous mass in the right superoposterior mediastinum, which appeared to invade the right third rib and thoracic vertebra. It was thought to be a posterior mediastinal ganglioneuroma or its malignant transformation. Grossly, the tumor mass arose in the posterior arc and showed substantial growth out of the rib. Microscopically, the tumor consisted of interspersed multi-nucleated giant cells and stromal mononuclear cells, compatible with GCT. For GCT, a wide excision with elective radiotherapy should be considered. GCT must be differentiated from posterior mediastinal ganglioneuroma that can be treated by surgical excision alone.

Synovial sarcoma is an uncommon malignant mesenchymal tumor that occurs in the vicinity of the joints, bursae, and tendon sheaths. Typically the lesions are located in the extremities, especially in the lower extremities. They also occur in the abdominal and thoracic walls, but rarely in the head and neck. We experienced a case of synovial sarcoma of the rib in 17-year -old woman. We performed on bloc chest wall resection including the right second rib tumor, fi st and third ribs. The postoperative course was uneventful. She received chemotherapy because of a relapse of the tumor in sternum and both lung during follow-up.

Telangiectatic osteosarcoma is a rare variant of osteosarcoma. The rib is an uncommon primary site for conventional osteosarcoma, and even more for telangiectatic osteosarcoma. Because this tumor consists of single to multiple cystic cavities that contain blood or necrotic tumor with no appreciable areas of sclerosis, careful observation is needed to differentiate this malignancy from other benign cystic lesion. Therefore primary differential diagnosis including telangiectatic osteosarcoma is important, although rib is not the predilection site of telangiectatic osteosarcoma. We present a case of telangiectatic osteosarcoma arising in a rib. We reviewed the literature concerning telangiectatic osteosarcomas and primary osteosarcomas arising from the rib. The differential diagnosis of telangiectatic osteosarcoma and clinical features of osteosarcomas arising from unusual locations were discussed.

Aneurysmal bone cyst(ABC) is a benign lesion and generally occurs in the long bones and vertebral column. ABC of the rib is an uncommon entity. We reported a case of ABC originating in the left first rib. The patient was a 19-year-old woman and presented with palpable mass on the shoulder. Chest X ray and MRI showed a large expansile mass, with multiple cystic areas, arising from the left first rib and bulging out into retroclavicular and paravertebral soft tissue, so the lesion was initially misdiagnosed as a soft tissue malignant tumor destructing adjacent rib. On histological examination, the mass, which was surrounded by a peripheral band of mature trabecular bone, consisted of multiple anastomosing cavernous blood channels separated by fibrous septa that containing osteoid, myxochondroid material and osteoclast-type giant cells.

Primary xanthoma of the bone is a rare benign neoplasm, and it is extremely rare to find this in the ribs. It is most commonly reported in soft tissue and it associated with hyperlipoproteinemia. A 54-years-old male who complained of left chest pain had an X-ray taken. It revealed a left 3rd rib tumor. The blood examinations for lipid and protein were normal. A resection was done for tissue examination. The mass was histolopathologically diagnosed as a xanthoma.

Purpose: Sternocostoclavicular hyperostosis (SCCH) is a disease of unknown etiology, which is characterized by periosteal reaction and endosteal hyperossification of the sternum, clavicles and upper ribs as well as ossification of the surrounding soft tissue. SCCH is a well recognized but uncommon condition which is important differential diagnosis to consider to avoid misdiagnosis and to differentiate the condition from malignant process. But few studies have reported long-term clinical result of SCCH. We report long-term clinical result of SCCH. Materials and Methods: From 1986 to 2000, 17 cases of SCCH were followed up over two to 14 years. We evaluated the radiologic, pathologic and clinical results. Results: Four men and thirteen women were studied. The age when first symptom appeared were raged from17 to 60(average-48.7) There are no specific bacteriological, serological or histological finding. Usually a permanent increase in the erythrocyte sedimentation rate is found. The radiological examination showed the signs of proliferate destructive arthritis in most case. The majority of patients respond to NSAIDs and antibiotics. Conclusion: Sternocostoclavicular hyperostosis is uncommon benign condition, but important condition in the differential diagnosis of inflammatory or malignant process of this joint.

Solitary plasmacytoma of bone is a rare disease that accounts for only about $3{\sim}5%$ of all plasma cell tumors. Especially, no case of solitary plasmacytoma of a rib origin has been described in the Korean literature. A 54 year old Korean man was referred to our hospital for further evaluation of a lung mass that had been detected on a screening chest radiograph. A tumor with a left 6th rib origin was revealed by the computed tomography(CT) and positive emission tomography (PET-CT); therefore, surgical resection was performed. The histopathological findings of the tumor revealed plasmacytoma of a rib origin. The postoperative screening test revealed no evidence of multiple myeloma. Postoperative radiation therapy was not performed, and no new lesion has been noted during the 2 years of follow up.

Osteochondromadevelop most commonly at distal femur, proximal humerus and proximal tibia, but the rib osteochondroma was reported less commonly. In this report, scapular snapping syndrome complicated by adventitious bursa and soft tissue pseudotumor surrounding the osteochondroma of the $6^{th}$ rib body was treated successfully by surgical excision of them. We report this rare case with reviewing the relevant literature.
