Cryptococcosis is a subacute or chronic inflammation that's caused by infection from cryptococcus neoformans in the soil or dust that's contaminated by pigeon droppings. Pulmonary cryptococcosis occurs in immunocompromised patients, and particularly in HIV positive patients, but it rarely occurs in immunocompetent individuals. It is most often detected as asymptomatic single or multiple nodules that are found by chest X-ray examination. In these situations, the diagnosis for most cases is made by the histology of the resected lesion. We report here on a case of solitary nodular pulmonary cryptococcosis that occurred in a 32 years old female patient who underwent thyroidectomy for treating her thyroid cancer.

Pulmonary sequestration is a relatively rare malformation. Infection with common pyogenes is a frequent complication in this disease. We report here on a case of intralobar sequestration that was infected with Mycobacterium tuberculosis in the absence of any other site of tuberculous infection. A 40-year man presented with a small amount of hemoptysis, and the man had been previously diagnosed with bronchiectasis 3 years ago. Chest computerized tomography revealed bronchiectasis with pneumonia in the left lower lobe and there was a large feeding artery from the thoracic aorta. A lobectomy of the left lower lobe was conducted via thoracotomy and the final pathologic examination confirmed pulmonary tuberculosis limited to the intralobar sequestrated lung. The patient underwent anti-tuberculous chemotherapy from the postoperative $7^{th}$ day and he was discharged without any adverse event.

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.

Cytomegalovirus (CMV) pneumonitis leading to inflammation and obstruction of the tracheobronchial tree may cause the cystic changes in the lung. We performed segmentectomy of lung under the diagnosis of congenital cystic lung disease in an infant of 2 weeks presenting severe respiratory failure. Histology and serology confirmed congenital CMV bronchiolopneumonitis.

Pulmonary blastoma are a family of tumors in which the glands or mesenchyme composing the neoplasm are primitive or emb yonal in appearance. We report a pulmonary blastoma occurring in a 31 years old man. An abnormal shadow was detected in the right lower lung field in a routine chest X-ray film. The preoperative imaging films showed about a 5cm sized well circumscribed solid tumor of the right lung. A preoperative clinical diagnosis of primary lung cancer was considerd. The operative field showed that the hard, round mass, 6$\times$5$\times$4cm in diameter was localized in middle lobe of the right lung, and partially adhered to the upper lobe, pericardium and diaphragm. Right middle lobe lobectomy, right upper lobe wedge resection, partial pericardiectomy and diaphragm resection with plication was performed with radical Iymph node dissection. Histopathologic diagnosis was pulmonary blastoma (Biphasic blastoma). It is considered that the prognosis of biphasic blastoma is worse than WDFA(well differentiated fetal adenocarcinoma). There are no other available treatments except for surgical resection. It is suggeste that it is necessary to collect as many cases as possible, to make definite classifications and to examine the clinical course and prognosis of pulmonary blastoma.

The therapeutic results of pulmonary resection for metastatic bone and soft tissue sarcomas were analyzed. From 1986 to 1996, 14 patients(11 male and 3 female) underwent 15 pulmonary resections for metastatic sarcomas. One(7.1%) patient had 2 thoracotomies for recurrences. The number of metastatic tumors were from one to five. The primary malignant tumors were from bone in 4 and from soft tissues in 10. Mean survival time after thoracotomy was 29.2 months, and Kaplan-Meier's 5-year survival rate from the first metastasectomy was 33.2%. Three patients who had the tumor free interval period over 3 years were alive(mean survival period 52.6 months), whereas eleven patients of the less than 3 years were dead with disease(mean survival period 17.3 months). These results suggested that pulmonary. metastasectomy in bone and soft tissue sarcoma may prolong the survival rate.

음성의 생성기전은 폐의 호기에 의하여 성대가 진동하여 원음이 발생하고, 원음이 하인두, 구인두, 비인두, 구강 등의 성도를 통과하면서 공명이 일어나며, 혀와 입술의 운동에 의하여 조음이 일어나서 결국은 음성이 생성되게 된다. 저자는 음성을 생성하는 후두 및 성도의 음성외과학적 구조 및 생리에 대하여 주로 언급하고, 성도에 발생하는 다양한 질환중 음성에 영향을 주는 질환만을 선택하여 간략히 설명하고자 한다. (중략)

Primary malignant melanoma occurring in the lung is very rare and only few cases have been reported in the literatures. We have experienced one case of primary malignant melanoma of the right middle lobe. The patient was a 65-year-old male who had cough with blood tinged sputum for one month. Chest computed tomography showed about 4.5$\times$3 cm sized mass at the right middle lobe encasing the bronchus. Percutaneous needle biopsy was performed and confirmed to malignant melanoma. Physical examination and additional clinical history showed that the mass had not metastasized to other possible primary sites. The patient underwent thoracotomy with right middle lobe lobectomy. Histologically, the tumor showed sheets of tumor cells that have nuclear atypia and melanin pigment Postoperative course was uneventful and the patient has been followed up for 24 months with no recurrence.

Hemangiopericytoma of the lung is a very rare malignant tumor despite it's high vasculities of the lung, because, this tumor arises from the pericytes enveloping capillaries. A pulmonary hemangiopericytoma was diagnosed in a 63-year-old female who had complained of cough, sputum, and intermittent chest pain for about 8 years. She was admitted to our hospital, because of progressive severe dyspnea on exertion and orthopnea for about 3 months. She was taken explothoracotomy and left pneumonectomy including evacuation of lots of blood clots due to ruptured large tumor and ineffective drainage with closed thoracic tube. She was discharged at post-operative 7 days under very good condition. She has been treated with radiotherapy&chemotherapy since then.

"소기도"라 일컬어지는 해부학적 부위는 말단부 막성 세기관지와 호흡성 세기관지로 구성된 직경 3 mm 이하의 기도부위이다. 방사선학적으로는 고해상 전산화단층촬영(CT)에서 흉막직하의 직경 약 1.0 cm으로 이루어진 2차 소엽내의 중심부에 위치하게 된다. 그러므로 이 부위의 질환때에는 중심소엽성 세기관지내의 가득찬 물질로 인해 나타나는 중심소엽성 결절들과 선상음영들이 보인다. 이외의 소견으로는 중심소엽성 폐기종, 모자이크 모양의 폐음영, 분절하 무기폐등이 있고, 호기시 CT 촬영에서 나타나는 공기포획이 있다. 최근에는 다검출기형식의 CT (multidetector CT)의 발전으로 인하여 이차원 재구성 (2 dimension reformat) 관상면, 시상면 CT 스캔을 매우 명확하고 빨리 얻을 수 있고, 기관지에 대한 삼차원 볼륨 영상 (3 dimentional volume rendering image) 등을 얻어서 가시적인 효과를 높이고 진단의 정확성에 보다 더 접근하게 되었다. 소기도를 침범하는 질환은 일차적인 것과 이차적인 것이 있는데, 병리조직학적으로는 원인별로 흡연으로 인한 소기도 질환, 세포성 세기관지염, 수축성 세기관지염, 증식성 세기관지염등으로 구분하며 여기에는 이와 같은 병리질환을 일으키는 다양한 원인들이 포함된다. 이외에도 드문 질환으로 미만성 범세기관지염, 광물질에 의한 소기도 질환등이 있다.
