Low-grade endometrial stromal sarcoma (ESS) is an uncommon gynecologic malignancy of mesodermal origin. Pulmonary metastasis of low-grade ESS can occur years and decades after the treatment of the primary disease. Low-grade ESS is frequently mistaken as benign uterine neoplasm like uterine leiomyoma, which can potentially lead to a misdiagnosis. We present a case of a 42-year-old woman with low-grade ESS, that initially presented as an incidental lung mass with multiple pulmonary nodules, seven years after an uterine myomectomy. A $6.9{\times}5.8cm-sized$ intrapelvic mass suspected of uterine origin was discovered while searching for potential extrathoracic primary origin. A pelviscopy and simultaneous thoracoscopic lung biopsy were conducted for pathologic diagnosis. Finally, the diagnosis was confirmed as low-grade ESS with lung metastasis based on the histopathologic examination with immunohistochemical stain, which was showed positive for CD10 and hormone receptor markers (estrogen and progesterone receptors) in both pelvic and lung specimens.

Synovial sarcoma is a malignant soft tissue neoplasm that occurs frequently in the extremities of young adults, near large joints. The lung is a common site of metastasis but an extremely unusual primary site for synovial sarcoma. We report an unusual case of primary synovial sarcoma that arose in the lung of a 59-year-old woman. The tumor had histologic and immunophenotypic features consistent with biphasic synovial sarcoma These features included of an intimate admixture of cytokeratin and epithelial membrane antigen(EMA)-positive neoplastic epithelial cells and vimentin-positive fibroblast-like spindle cells. The patient had a closed thoracomy drainage and doxycycline pleurodesis for malignant loculated effusion and showed tumor extension in the left whole lung 4 months after pleurodesis. This case is an usual addition to the small number of published reports on primary pulmonary synovial sarcoma The distintive features of this neoplasm allow it to be distinguished from a variety of primary and metastatic malignancies in the lung.

Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome. Currently used lymph node maps have been reconciled to the internationally accepted International Association for the Study of Lung Cancer (IASLC) map published in the seventh edition of TNM classification system of malignant tumours. This article provides computed tomographic illustrations of the IASLC nodal map, to facilitate its application in day-to-day clinical practice in order to increase the appropriate classification in lung cancer staging.

Renal transplant recipients who received immunosuporessive agent are in high risk of development Kaposi's sarcoma. In Korea a few report of Kaposi's sarcoma has been pubilshed but any report of intrathoracic Kaposi's sarcoma provedn by open lung biopsy has not been pulbilshed until now. We report a case of intrathoracic Kaposi's sarcoma developed in a 25 year old Korean man, who had been operated renal transplantation due to end stage renal disease and received cyclosporine and prednisolone as immunosuppessive agent, without any other organ involvment and was proven by open lung biopsy. Although discontinuation of immunosuppressive agent, temporary symptomatic and radilolgic improvement were observed, he died 11 days later after open lung biopsy because of intractable resiratory failure.

The pulmonary sarcomatoid carcinoma is a rare malignant tumor, which is composed of an admixture of carcinomatous and sarcomatous components, and accounts for 0.3% of all pulmonary neoplasms. Clinicopathological features are often related to anatomical location: central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic test had a low yield in detection sarcomatoid carcinoma. Metastasis to the regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is about 15 months. We report two cases of pulmonary sarcomatoid carcinoma with review of literatures.

Amyloidosis is a rare disease which is characterized by the deposition of a histochemically specific substance called amyloid in many tissue bodies, and causes various symptoms according to the organs involved. Amyloid is usually recognized by its staining reaction with Congo red stain. Primary pulmonary amyloidosis is very rare. Nodular pulmonary amyloidosis is an uncommon entity that usually manifests itself as an asymptomatic incidental finding on the chest roentgenogram and is misdiagnosed as lung cancer or pulmonary tuberculosis.

Lymphangioleiomyomatosis(LAM) is defined as an abnormal proliferation of smooth muscles in the lung tissue throughout lymphatics, vascular and bronchial structure. A 52-year-old postmenopausal woman was admitted to our hospital for recurrent pneumothorax. She was treated for medroxyprogesterone by LAM 1 month ago. We performed operation of pulmonary partial resection and pleurodesis. The patient is receiving continuous medroxyprogesterone and Leuplin administration, and currently, 6 months after the operation, is still showing good results.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm of uncertain histiogenesis, with a complex but characteristic histologic appearance. We experienced a typical lesion of pulmonary sclerosing hemangioma clinically and histologically, which was removed from the right lower lobe of 22-year-old male and was reviewed by Darryl Carter at Yale University. We discussed histiogenesis, microscopic features and prognosis of the sclerosing hemangioma.

폐에 발생하는 원발성육종은 모든 연령측에서 매우 드물고 종야잉 꽤 커질 때 까지 증상이 없는 경우가 있다. 갑작스런 흉통을 주소로 내원한 50세 여자는 자발성 혈흉을 동반한 폐종양이 발견되어 수술을 시행하였다. 수술은 우상엽절제술과 임파절곽청술을 시행하였고 술후 병리조직학적 검사에서 섬유육종으로 진단되었다.

Carcinosarcoma of the lung is an admixture of cardinomatous and sarcomatous lesion and accounts for 0.3% of all pulmonary neoplasm. Clinicopathological features are often related to anatomical location : central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic tests had a low yield in detection carcinosarcoma. Metastasis to regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is less than one year.Two cases of carcinosarcoma patients are reported here - one case is composed of undifferent cell carcinoma and spindle cell sarcoma in the male of 72 year old and the other case squamous cell carcinoma and spindle cell sarcoma in the male of 65 year old.
