We performed thoracoscopic resection for diagnosis in 41 year-old-female presenting with multiple pulmonary nodules in both lung fields, which was detected incidentally on routine chest x-ray and followed by additional exmaminations including chest CT scan and percutaneous needle aspiration biopsy under the presumptive diagnosis of metastatic cancer. During thoracoscopy, the result of the frozen section analysis of multiple masses revealed strong evidence of leiomyoma. In her past medical history, she had undergone myomectomy, and hysterectomy, 7 year ago and 10 year ago, respectively. Based on permanent, special staining of specimen, estrogen receptor assay and review of past specimen of uterine myoma the final diagnosis was benign metastasizing leiomyomata from uterine myoma, the report was very uncommon in Korean and English literatures. The patient has been followed up for 2 year without special therapy, such as hormonal therapy.

We report two cases of giant soft tissue sarcomas metastatic to the lung from lower extremities. The lung metastasis occurred 2 years later from original diagnosis in 27-year-old woman with hemangiopericytoma and 8 years later in 54-year-old woman with synovial sarcomtt. We had performed pleuropneumonectomies with partial resection of pericardium involved. The postoperative courses were uneventful and postoperative adjuvant therapy was begun.

Clinicians should looking for techniques that helps to early diagnosis of cancer, because early cancer detection is critical to increase survival and cost effectiveness of treatment, and as a result decrease mortality rate. Medical images are the most important tools to provide assistance. However, medical images have some limitations for optimal detection of some neoplasias, originating either from the imaging techniques themselves, or from human visual or intellectual capacity. Image processing techniques are allowing earlier detection of abnormalities and treatment monitoring. Because the time is a very important factor in cancer treatment, especially in cancers such as the lung and breast, imaging techniques are used to accelerate diagnosis more than with other cancers. In this paper, we outline experience in use of image processing techniques for lung and breast cancer diagnosis. Looking at the experience gained will help specialists to choose the appropriate technique for optimization of diagnosis through medical imaging.

We experienced two cases of pulmonary hamartoma, which is the most common benign tumor of lung. But the hamartoma is rare disease, because the most neoplasm of the is malignant. The importence of pulmonary hamartoma is the necessity of differential diagnosis between lung cancer and benign tumor of the lung. Recently, the development of FNAB [Fine needle aspiration biopsy] shows accurate diagnostic results.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is becoming a standard method for invasive mediastinal staging and for the diagnosis of paratracheal and peribronchial lesions. It is essential to understand the technical aspects of EBUS-TBNA to ensure safe and efficient procedures. In this review, we discuss the practical aspects to be considered during EBUS-TBNA, including anesthesia, manipulation of equipment, understanding mediastinal ultrasound images, target selection, number of aspirations needed per target, sample handling, and complications.

A 43-year-old woman with breast cancer who was on neoadjuvant chemotherapy presented with cough, sputum and mild fever. High-resolution computed tomography showed diffuse ground glass opacities in bilateral lungs and subpleural patchy consolidations. Initially, she was thought to have pneumonia or interstitial lung diseases such as drug-induced pneumonitis and treated with antibiotics and steroids. She subsequently got breast cancer surgery because of disease progression, and concurrent thoracoscopic lung biopsy revealed metastatic carcinoma of the lung from breast cancer. The diagnosis of suspected interstitial lung disease can be made without lung biopsy, but malignancy should always be considered and lung biopsy should be performed in the absence of a definitive clinical diagnosis.

동시성 원발성 폐암은 전체 폐암의 1∼2%정도로 드문 암으로 술전 진단이 어렵고 수술 중이나 수술 후에 진단되는 경우가 대부분이다. 특히 동종 조직학적 특징을 나타내는 경우 진단이 어렵고 술전 폐에서 폐로 전이된 원격 전이로 오인될 수 있다. 본 교실에서는 수술 중 발견된 서로 다른 편편상피암을 가지는 동시성 원발성 폐암을 1례 경험하였기에 보고하는 바이다.

폐모세포종은 매우 드문 원발성 폐 종양으로 종괴를 구성하는 선상구조나 간엽조직 성분이 미분화된 태생기때 조직으로 구성되어 있는 종양으로 주로 성인 및 소아에서 발생한다. 본교실에서는 단순 흉부 사진에서 우측폐 하엽에 약 5Cm크기의 이상음영을 보이는 31세 남자에 발생한 폐모세포종 1례를 경험하고 이를 보고하고자한다. 수술전 임상 진단은 원발성 페종양으로 생각되었다. 수술 소견상 직경 6$\times$5$\times$4cm 크기의 단단하고 등근 종괴가 우측폐중엽에 국한되어 있었으며 부분적으로 폐상엽, 심막과 횡격막에 부착되었다. 우측 폐중됩 절제술 및 폐상엽 부분절제와 광범위한 임파절 절제를 동반하여 부분적으로 심막과 횡격막을 절제하였다. 병리조직학적으로 이상성 폐모세포종으로 진단되었다. 이상성 폐모세포종의 예후는 분화가 좋은 태아 선암종에 비해 나쁘며 외과적 절제술 이외에 특별한 치료는 없다. 폐모세포종의 임상적 경과 및 예후와 상세한 분류를 위해서는 가능한한 많은 증례를 수집할 필요가 있다고 생각된다.

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.
