Lung cancer remains the most common cause of cancer-related deaths worldwide. Although there are many possible treatments, including targeted therapies such as epidermal growth factor receptor tyrosine kinase inhibitors and anaplastic lymphoma kinase inhibitors, new therapeutic strategies are needed to improve clinical outcomes. Immunotherapy through the use of immune checkpoint inhibitors has provided one of the most important breakthroughs in the management of solid tumors, including lung cancers, and has shown promising results in numerous clinical trials. This review will present the current status of immunotherapy for lung cancer and future perspectives on these treatments.

전신쇄약을 주소로 내원한 60세 남자환자가 흉부 방사선 사진상 좌폐하엽에서 폐종양이 발견되었다. 좌폐하엽절제술과 종격동 임파선 절제를 시행후 병리조직검사상 폐의 대세포 신경내분비암으로 진단되었다. 폐의 대세포 신경내분비암은 드문 질환으로 저자들은 이를 치험하였기에 보고하는 바이다.

Patients with severe emphysema have a higher risk of developing lung cancer, and their surgical risk increases when emphysema is accompanied by a giant bulla. Here, we describe a patient who had an emphysematous giant bulla in the right upper lobe that was treated with an endobronchial valve placement. Subsequently, a cancerous lesion on the contralateral lung was successfully removed by lobectomy.

혈관 주위 세포종은 주위 세포에서 발생하는 매우 드문 혈관 종양으로, 주로 하지나 후복강에 생기며, 완전 절제가 치료 원칙이다. 혈관 주위 세포종은 악성 가능성이 있는 종양으로 재발 및 전이가 있을 수 있으므로, 치료 후에도 주의 깊은 추적 관찰을 요한다. 저자들은 10년 전 좌측 후복강의 혈관 주위 세포종으로 완전 절제를 시행한 환자에서 발생한 폐로 전이된 혈관 주위 세포종을 수술적 절제하였다.

폐의 카르시노이드 종양은 기관지 상피의 Kulchitsky 세포에서 유래하는 신경내분비 종양이다. 폐의 카르시노이드는 대개는 중심부에 위치한다. 그러나, 비전형적 카르시노이드는 주변부에 위치하기도 하며 조직학적으로 악성도가 높다 흉막에서 기원한 카르시노이드에 대한 보고는 거의 없는 상태로 저자들은 벽측 흉막에 위치하며 폐실질내로의 침윤이 없이 흉벽을 침윤하는 전형적인 카르시노이드를 보고하는 바이다.

Pulmonary benign metastasizing leiomyoma (PBML) is defined as metastasis of a leiomyoma to lung tissue. It was first reported in 193 7. PBML is known as a benign disease, but can undergo malignant transformation. Only 1 case of the malignant transformation of PBML to leiomyosarcoma has been reported previously. In this report, we present a case of malignant transformation of PBML.

Primary malignant lymphomas of the lung are rare neoplasms representing 3.6% of all extranodal lymphomas and less than 1% of pulmonary malignancies, with its distinct clinicopathological features. A 60-year-old symptomatic man, who was a former non-smoker, had a cough and sputum. Chest roentgenogram and computed tomographic scan showed the presence of a posterior mass in the basal segment of the right lung. Transthoracic needle aspiration cytology was inadequate for the diagnosis of cancer. A subsequent right thoracotomy was carried out, which showed a primary pulmonary lymphoma of the bronchus-associated lymphoid tissue.

The role of respiratory cytology is to detect and classify pulmonary disease, with an emphasis of neoplastic disease, so that proper therapy can be instituted. As in many branches of cytology, the recognition of malignancy in the cells obtained from the respiratory tract is more straightforward than identifying the type of tumor cell. It is important to accurately determine the true cytopathological cell type in cases of primary lung cancer and to know the accuracy of the diagnosis achieved by the cytological procedures. The well differentiated tumors have characteristic cytoplasmic and nuclear abnormalities that enable physicians to firmly categorize these lesions, as in squamous cell or adenocarcinoma, but some moderately and most poorly differentiated tumors show few distinctive features. This article reviews the malignant and reactive pulmonary cytologic findings and we also report on some of their pitfalls and the cytologic criteria.

The major categories of neuroendocrine tumors of lung are typical carcinoid, atypical carcinoid, large cell neuroendocrine carcinoma, and small cell carcinoma. The histologic classification criteria of neuroendocrine tumors are well documented in the "WHO Classification of Tumors" based on mitotic figures and necrosis. Cytologic characteristics of neuroendocrine tumors are trabecular, acinar, and solid arrangement of tumor cells and occasional rosette formation. Nuclear chromatin patterns are characteristically described as "salt and pepper chromatin pattern". Many of cytologic classifications documented in the literature are before the "WHO Classification". In this review, the cytologic features of pulmonary neuroendocrine tumors are documented according to the WHO classification, and recent concepts of neuroendocrine tumors of lung are discussed.

Hamartoma had been considered as a congenital malformation of a tumerous lesion since the original description by Albrecht in 1904. Pulmonary hamartoma is able to classified as endobronchial and intrapulmonary hamartoma clinically, and is considered to benign mesenchymal neoplasms which originated in peribronchial connective tissue, and so called mesenchymoma by someone. We have experienced 3 cases intrapulmonary hamartoma which were discovered during routine chest film check up at all cases and are able to detailed histologic examination by electron microscopy at one case.
