  • Localized fibrous tumor of the pleura is very rare. Most of them are benign, but some are malignant. This clause does not relate with the rest of the sentence. The single best predictor of clinical benignity is whether the tumor can be totally resected. We experienced a case of localized fibrous tumor of the pleura in a 57 year old man with right chest pain and cough. He was informed of a $8{\times}5cm$ mass in his right lower lung field, which was benign 3 years ago. Preoperative chest x-ray showed an increased hazy density at right lower lung field, and CT scan showed a $12{\times}8cm$ huge mass, which was located in right lower thorax. Left thoracotomy was done to excise a $12{\times}8{\times}5cm$(1200gm) sized large mass delete. The patient was discharged without any complications postoperatively.

  • Mesothelioma is a primary tumor of the pleura. There are two forms of mesotheliomas; diffuse form and localized form. The majority of localized mesotheliomas are benign, but the tumor with pedicle recur at 20% after removal of it. Malignant localized fibrous mesothelioma is differential diagnosed pathologically and clinically with diffuse mesothelioma. Symptoms of localized mesothelioma are generally related to the size of the tumor. We presented one case of malignant localized fibrous mesothelioma. The patient was 32 years old female and chief complaints were dyspnea and dry cough. Sputum cytology and needle lung biopsy were not able to diagnose definitely the tumor. Explothoracotomy was carried out for definite tissue biopsy. At the time of operation, huge adult head size mass was in the right thoracic cavity. The surface of the mass was nodular, multilobular and had hard consistency. Pedicle was formed above first rib and its diameter was 4.5cm. There was no adhesion except to RUL. Frozen biopsy suggested mesothelioma. Extirpation of the mass, right upper lobectomy. and partial pleurectomy were carried out.

  • Localized fibrous tumor of the pleura is a rare condition. Most follow a benign course and they are round as an incidental finding during routine chest X-ray. A small proportion of these tumors are malignant and have characteristic clinical and histopathological features. In this paper, we report three cases of localized fibrous tumors of the pleura, one malignant associated with asymptomatic hypoglycemia, the others benign. In a malignant case, the tumor was reseated through thoracotomy and the hypoglycemia was relieved immediately. In two benign cases, tumors on small pedicles were resected using video-assisted thoracic surgical technique.

  • Osteoblastoma is a relatively rare benign bone tumor representing less than 1% of all bone tumors. The tumor usually involves the spine and sacrum of young individuals, less than 10% being localized to the skull, and nearly half of these affect the mandible, especially the posterior segments. In clinical finding, osteoblastoma present mainly with pain, swelling, and expansion of bone cortex. Radiographic appearances are variable, but frequently a well-delineated radiolucent lesion containing varying amounts of mineral deposits is seen. Histologically, ostoeblastoma is consists of irregular trabeculeae of osteoid and immature bone present within highly vascular connective tissue matrix. Osteoblastoma must be differentiated from a number of bone-producing lesions, including osteoid osteoma, fibrous dysplasia, ossifying fibroma, fibrous dysplasia, and osteosarcoma. If diagnosis may be mistaken for osteosarcoma, there are risks of more aggressive and irreversible treatment. Differential diagnosis of osteoblastoma is important. The preferred treatment of osteoblastoma is conservative approach and surgical excision. Recurrence following surgical intervention is rare. We treated osteoblastoma located in premolar area of mandible by excision with preservation of vital structure, such as nerves and teeth. So we report our clinical treatment with literature review

  • Osteoid osteoma is a benign osteoblastic tumor composed of osteoid and atypical bone, with a loose, highly vascular fibrous marrow. The tumor has been reported in most of the bones of the body, but it is infrequently localized to the hand. The scaphoid is the carpal bone involved most frequently. Typically the lesions are painful and respond to aspirin. Roentgenologic finding of the central area of lucency surrounded by sclerotic bone often is diagnostic. Block excision with bone grafting is an acceptable method of treatment. We report a case of osteoid osteoma in scaphoid with a review of the literature.

  • Most clinicians have taken a lot of interest in tumors arising from the bony thorax because not only of their rarity and predictable diagnosis which could be reflected as a unique radiologic shadow but also variable surgical modes for maintenance of chest wall stability encountered after en-bloc resection. By the retrospective review, we have analyzed 24 cases of primary bony thorax tumors which were experienced and surgically treated at the St. Mary`s hospital of Catholic Medical College from Jan. 1969 to Sept. 1984. The results are as follows: 1. Age incidence was evenly distributed through all decades and the male-female ratio is 15:9. 2. 16 cases out of 24 were benign tumors and the commonest one of which was fibrous dysplasia. 3. Remaining 8 cases were malignant tumors and among which osteogenic sarcoma was the commonest one. 4. The majority of tumors [22/24] were developed from the rib and the remains were from the sternum. 5. Common manifestation were palpable mass or swelling and localized tenderness. 6. Various kinds of operative procedure were underwent: single resection of rib including tumor,14 cases; multiple resection of ribs with chemotherapy or myoplasty, 2 cases; en-bloc resection of the chest wall and reconstructive procedure, 5 cases; partial resection of sternum, 1 case; bone biopsy and chemotherapy, 2 cases.
