Pleural mesothelioma is usually divided into two forms of localized and diffuse type. Localized pleural fibrous mesothelioma is uncommon mesodermal neoplasm, which may occurs in both sexes and at the age of 50 years. This type of mesothelioma is usually asymptomatic and detected on routine chest X-ray and made fibrous tissue and shows of collagen fibers microscopically. Most localized fibrous mesothelioma arises from the visceral pleura and is well encapsulated and pedunculated mass. CT findings included well delineated, often lobulated, non-calcified soft tissue masses in close relation to a pleural space, associated pleural thickening, and absence of chest wall invasion and a peripheral or fissure location. Three cases of localized pleural fibrous mesothelioma diagnosed by resectional surgery were reported with the review of literature.

Localized fibrous tumor of pleura is submesothelial origin and related terms with localized mesothelioma, giant sarcoma of visceral pleura, post-inflammatory tumor of the pleura, pleural fibroma, submesothelial fibroma. This tumor is rare. We experienced a case of localized fibrous tumor.This 66 years old female was admitted with 2 years left persistant flank pain and mild dyspnea. Chest X-ray and CT scan showed a 12x10cm well-defined huge mass in the left subpulmonic area, and not metastatic lesion of any organs.Exploratory thoracotomy was done and a 14x10x8cm [650gm weight] sized mass was excised.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.

A 44-year-old man was transferred to our department for mediastinal mass. He had suffered from only an easily fatiguable condition for 1 month. A physical examination and laboratory finding of the patient disclosed no abnormality. A chest radiograph showed a soft tissue tumor in the posterior mediastinum. It was well circumscribed and ovoid. Invasions to adjacent organs were not seen. Therefore it was though the 5th intercostal space. The tumor mass was attached to the visceral pleura of the right upper lobe by a pedicle and this pedunculated tumor laid entirely within the pleural cavity. Excision of the tumor which measured 7$\times$7$\times$3cm was done easily. Pathologic studies confirmed the diagnosis of localized fibrous tumor of the pleura. Localized fibrous tumor of the pleura is rare, This tumor along ith the evidence from ultrastructural and immunohistochemical studies has led most researchers to conclude that localized fibrous tumor is not of the mesothelial origin but arises in the submesothelial connective tissue.

Localized fibrous tumor of the pleura (LFTP) is of submesothelial fibrous origin, which has been called pleural fibroma and has been confused with mesothelioma. We experienced a case of LFTP in a twenty nine year old man. The tumor arose from the right parietal pleura with long stalk. Chest X-ray and CT scan showed a 6$\times$5$\times$4cm well-defined mass in the right costophrenic angle. Wo evidence of metastasis was noted. Exploratory thoracotomy with enbloc excision of 6$\times$5$\times$4cm mass was done. The fine needle aspiration cytology and histopathologic features indicated the tumor to be malignant, and biologic behavior was discussed.

흉막에 발생하는국소성 섬유성 종양은 드문 질환으로 대부분의 경우 단순흉부촬영상 우연히 발견되며 특징적 인 임상상 및 조직병 리학적 소견을 보인다. 본 논문에서는 증상없는 저혈당을 동반한 악성 국소성 섬유성 종양 1례 및 양성 국소성 섬유성 종양 2례를 보고하고자 한다. 악성의 예에서는 개흉술을 통해 종양을 절제해 내었고 수술직후 저혈당의 소실을 관찰할 수 있었으며 양성 2예에서는 비디고 흉강경을 이용하여 종양을 절제할 수 있었다.

Cytokeratin 19 (CK19) expressed in epidermis of skin, bulge region of hair follicle, outermost layer of outer root sheath and proximal and distal to bulge. Vimentin is a fibrous protein that localized in cytoplasm of fibroblast and forms cytoskeleton to maintain shape of cell and nucleus. In this study, CK19 and vimentin in skin were confirmed with light, fluorescence and transmission electron microscope. As a result, CK19 was localized epidermis, hair follicles, outer root sheath and nucleus of Merkel's cell. However, vimentin was localized some epidermis, dermis, hypodermis and nucleus of Merkel's cell. The role of CK19 is self-renewal and homeostasis in skin. Also, hair follicle regeneration and hair growth is known to be related. It is supposed that required of structural proteins that make up cytoskeleton is increased. Thereby, expression of CK19 is increased. It is considered that vimentin localized in order to stabilize structure of cell and cytoskeleton of fibroblasts. Also, CK19 and vimentin present in nuclei of Merkel's cell, and to act as a fibrous protein that make up end of a nerve fiber present in Merkel's cell and paracrine function of Merkel's cell.
