Solitary Plasmacytoma of the Rib: A case report / 대한흉부외과학회지

Solitary plasmacytoma of bone is a rare disease that accounts for only about 3~5% 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.

Chondromyxoid Fibroma of the Rib: Report of one case / 대한흉부외과학회지

Chondromyxoid fibroma (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.

Surgical Treatment of Langerhans Cell Histiocytosis in the Rib: Two cases report / 대한흉부외과학회지

Langerhans cell histiocytosis (LCH) involves disorders previously referred as "histiocytosis X" (including eosinophilic granuloma, Letterer-Siwe, and Hand-Schuller syndrome). Its clinical patterns are various and it is a basically benign tumoral condition but with a strong tendency toward dissemination and destruction. Its natural history is unpredictable. But, in solitary bone lesion, wide resection with tumor-free margin is required in order to provide the best chance for a cure. In the majority of patients LCH is a osteolytic lesion with a predilection for calvarium and is rarely seen in the skull base and the femur. LCH of rib, especially if solitary, is relatively rare. We report two rare cases of solitary LCH developed in the rib, which were successfully treated by surgical resection.

Adult Onset of Langerhans Cell Histiocytosis in the Rib: Report of 2 cases / 대한흉부외과학회지

Langerhans cell histiocytosis (LCH), previously called histiocytosis X, refers to a spectrum of disease characterized by idiopathic proliferation of histiocytes producing focal or systemic manifestations. Causes and pathogenesis remain unclear. The basic histopatholgic findings are identical in the three well-established clinical syndromes (eosinophilic granuloma, Hand-Shuller-Christian disease, Letterer-Siwe disease). The disease has a predilection for children, although it may occur in adults. We experienced two cases of adult onset Langerhans cell histiocytosis in the ribs. One case was associated with diabetes insipidus and the other case had a solitary lesion.

Primary Giant Cell Tumor of Rib-Unusual Location / 대한흉부외과학회지

Giant cell tumor rarely occurs in ribs. Usually it is located in the posterior arc. We reported a very rare case of primary giant cell tumor of rib in the anterior arc with review of literatures.

Synovial Sarcoma of the Rib: Report of a Case / 대한흉부외과학회지

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 en bloc chest wall resection including the right second rib tumor, first 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.
