For effective radiotherapy, it should always be considered that calculation of different dose distribution in heterogenous tissue is important particularly on lung which has low density and large volume. To take precise dose distribution of 6MV X-ray in the thoracic cage, the authors had made a tissue equivalent phantom for thorax, measured dose distribution by thermoluminescent dosimeter and mm dosimeter, and derived methmetical equation coincided with provided theoretical formula. In comparision with isodose curve on case of homogeneous soft tissue, dose of heterogeneous lung tissue had been shown increase about 4% per cm depth on one and multiportal field, less than 15% difference on rotation field for esophagus, and around 20% difference on rotation field for lung according to the degree of rotation angle that must be corrected by dose compensation.

The mortality rate of the invasive pulmonary aspergillosis to be able to developed during chemotherapy induced myleosuppressionin is high in hematologic malignancy patients despite antifungal treatment. Effective antifungal treatment combined with operation can decrease the mortaligy rate of the invasive pulmonary aspergillosis. Recently, we experienced the successful management of the two cases of invasive pulmonary aspergillosis in acute lymphoblastic leukemia through effective antifungal treatment and surgical resection. We report this cases with review of literature.

혈관에서 기원되는 종양은 혈관외피 세포로부터 발생되는 종양 혈관외피종과 glomus tumor)관 혈관내피 세포로부터 발생되는 종양(를상피 혈관내피종)의 두가지로 구분된다. 이들은 매우 드물게 발생되며 악성종양의 특성을 가지고 있는데, 폐에서 발생된 경우에는 무증상의 작은 종괴로부터 증상이 있는 커다란 종양 의 형태로 나타난다. 최근 저자들은 단일성의 유상피 혈관내피종과 혈관외피종 각각 1례를 치험하였기에 문헌고찰과 함께 보 고하는 바이다. a Tumors of vascular origin are subdivided into two groups: those composed of pericytes (hemangiopericytoma and glomus tumor), and those composed of endothelial cells(hemangioendothelioma). They are uncommon, potentially malignant tumors, and in the lung, the tumors may present as a small asymptomatic nodule or a large symptomatic lesion. Recently we experienced two cases of solitary pulmonary vascular tumors(epithelioid hemangioendothelioma and hemangiopericytoma), and reviewed them with references.

Primary hemangioperiycytoma is quite rare tumor of the lung and arising from pericyte in external layer of capillaries. Most cases are developed in 4th and 5th decade, are asymptomatic, and have malignant otential. On chest radiography, primary pulmonary hemangiopericytoma shows lobulated, well demarcated, homogeneous soft tissue density. Microscopically, it consisits of numerous vascular spaces of variable size and shape separated by aggregates of tightly packed oval to spindle-shaped cells. Treatment of choice is surgical excision. We report a case of primary pulmonary hemangiopericytoma in a 16-year-old man who had well demarcated homogeneous mass in the superior segment of left lower lobe, but had no symptom. He had undergone left lower lobectomy. He has been followed up for 8 months but has no sign of relapse or metastasis yet.

The incidence of pulmonary leiomyosarcoma as primary lung tumor is very rare. Most of the primary leiomyosarcomas originate in the hilar region in relation to the main bronchus or pulmonary vessels and only a few originate more peripherally. This rare tumor can mimic bronchial carcinoma and present with local or systemic symptoms, or it may be discovered as an incidental finding on a routine chest X-ray. We report with review of literature, a case of incidental primary pulmonary leiomyosarcoma which originated peripherally. Huge mass was found on the left lung of a 61-year-old man on the chest X-ray peripherally. He underwent the surgical resection of the left pneumonectomy and the postoperative course was uneventful.

A 65-year-old-male had a mass in the oral cavity, and this was ultimately determined to be squamous cell carcinoma and he underwent wide excision for it. Postoperatively, he underwent the staging work up; this showed that he had other cancers in the esophagus, stomach and lung. We performed a curative resection of all the lesions simultaneously. We report here on a case of synchronous multiple cancers of the esophagus, stomach, lung and oral cavity.

Inflammatory myofibroblastic tumor was widely known as inflammatory pseudotumor, commonly developed as a solid mass in lung. The endobronchial inflammatory myofibroblastic tumor is a very rare case where only a few cases have been reported. We report a 13-year-old girl who had coughing for 5 months. The simple chest X-ray and computued tomography of the chest revealed a mass which obstructed the right lower lobe bronchus and pneumonic consolidation. The fiberoptic bronchoscopic finding was mostly gelatinous, gray-yellowish mass that obstructed the airway of right lower lobe bronchus nearly, and was considered as a chondroid hamartoma pathologically. Right lower lobectomy of lung was performed. The mass was confirmed as a endobronchial inflammatory myofibroblastic tumor The patient was discharged without complication and with outpatient followup.

In this paper, we present an extremely rare case of a primary intrapulmonary neurogenic tumor, in which localization of S-100 protein was investigated using immunohistochemical staining. The patient, who was a 47 year old man, experienced no symptoms, however, a routine chest X-ray revealed a round tumor like shadow in the hilar area of left lung. To confirm and cure the mass, surgery was performed. Histopathological examination of the excised tumor revealed it to be a primary intrapulmonary neurilemmoma. Immunohistochemical staining demonstrated the presen e of S-100 protein in the tumor cells.

Oncocytic carcinoid는 매우 드문 종양으로 단지 몇 례만이 문헌상 보고되고 있다. 본 저자들은 좌폐 상엽에 발생한 oncocytic carcinoid 1례를 치험하였는데 환자는 56세된 여자환로 특이한 증상은 없었다. 흉부 전산화 단층촬영상 좌폐상엽에 3$\times$3.5 cm 크기의 동종의 종괴를 보이고 있었다. 수술전 검사후 외과적절제술을 시행하였는데 육안적소견상 4$\times$3cm 크기의 경계가 명확한 황갈색의 종괴였으며, 병리조직학적 검사상 괴립성 호산성 세포질이 풍부한 양상을 보였으며 면역조직학적 검사에서는 cytokeratin에 양성반응을 보였으며 EMA와 chromograin에 국소적인 양성반응을 보여, 폐에 발생한 oncocytic carcinoid로 진단하였다. 수술후 환자의 상태는 양호하였으며, 현재 외래추적관찰중이다.

Pleuropulmonary bastoma (PPB) is a rare intrathoracic malignant neoplasm in children, differ from pulmonary blastoma in adults. PPB is usually aggressive and has wide-metastases at the time of diagnosis. The therapeutic medality of PPB is extensive surgical resection with neoadjuvant or adjuvant chemotherapy. We report a case of a cystic pieuropulmonary blastoma treated with surgical resection and adjuvant chemotherapy.
