Pulmonary siderosis is a pneumoconiosis caused by chronic iron inhalation. A diagnosis of pulmonary siderosis is based on a patient history of iron inhalation, on chest radiographic findings, and on accumulation of iron oxide in macrophages within the lung. A typical radiographic finding of pulmonary siderosis includes ill-defined micronodules that are diffusely distributed in the lung. We experienced a 52-year-woman with a $1.3{\times}1.5$-cm mass in the left upper lobe with multiple nodules in both lungs. Because the radiographic findings were atypical, we conducted a video-assisted thorascopic lung biopsy procedure to exclude the diagnosis of metastatic lung cancer. After confirming iron deposition in the lung tissue and knowing the patient's occupational history of welding iron, we concluded that this was a case of pulmonary siderosis.

Actinomycosis is a chronic suppurative granulomatous disease due to Actinomyces israelii characterized by multiple abscess and sinus tract formation with dense fibrous scarring. This disease, especially thoracic infection, is very rare in Korea so we are not famiIliar with to make diagnosis and treatment. Otherwise the unspecificity of the clinical symptoms and the lack of adequate examination recedure (as anaerobic fungus culture) are the causes of misdiagnosis. Thoracic actinomycosis is very similar to chronic infectious disease of the lung and chest or thoracic neoplasm. Recently we experienced a case of thoracic actinomycosis (bronchopulmonary) which had been confused with chronic lung abscess and pathologically confirmed as broncho-pulmonary actinomycosis. The purpose of this report is to review our experience more thorouly to enhance consideration of Artinomycosis.

Pulmonary malakoplakia is a rare lung lesion more frequently found in immunocompromised patients than in immunocompetent individuals. In this study, we report the challenging case of a young immunocompetent patient with an irregular pulmonary nodule with peripheral cysts who, after undergoing surgery, was diagnosed with malakoplakia. Due to the rarity of the disease and the similarity of this condition to malignant neoplasms, cytopathological or histopathological examinations are necessary for the correct diagnosis. A description of pulmonary malakoplakia with peripheral cysts has not been previously published in the literature.

Two hundred and seventeen patients underwent diagnostic rigid bronchoscopy or bionchofiberscopy to evaluate the cytologic diagnosis in the lung cancer patient at the department of chest surgery of Yon-Sei university, college of the medicine from 1971 to 1977 year. One hundred and twenty cases of these patients were taken rigid bronchoscopy and ninety four cases of these patient were taken bronchofiberscopy. Cytologic examination of the sputum was done in 214 cases and sputum cytology was positive in 50 cases [23.4%]. Rigid bronchoscopy was made in 120 cases and this bronchoscopic cytology including bronchial washing and bronchial biopsy was positive in 34 cases [28.5%]. Bronchofiberscopy was performed in 94 cases and was positive in 45 cases [47.5%]. Histopathologically, 41 cases [43.6%] were epidermoid cell carcinoma, 8 cases [8.5%]of undifferentiated cell type, 12 cases [12.8%]of adenocarcinoma, 8 cases [8.5%]of alveolar cell type, and the 25 cases were undetermined. Cytologic examination of the sputum lacks the accuracy of the bronchoscopies in terms of both localization and accurate histologic indentification of the type of neoplasm. Rigid bronchoscope has the advantage of permitting identification of a tumor in a central location and of providing a sufficient amount of biopsy material for accurate diagnosis of carcinoma. However, it has the disadvantage of limiting examination to the larger, more central portions of the tracheobronchial tree. Bronchofiberscope had the advantage of examine upper lobe as well as other portions of the tracheobronchial tree which could not be visualized with the rigid bronchoscopy. A positive diagnosis in bronchofiberscopy was obtained in the highest rate, 47. 8% [45 cases]. A1 last, if a bronchogenic carcinoma is suspected on the basis of either symptoms of an abnormality on the chest film the diagnostic work-up-sputum cytology, bronchial washing, bronchoscopic biopsy, scalene node biopsy, thoracentesis and mediastinoscopy explothoracotomy etc-should precede in an attempt not only to obtain the higher positive diagnosis but also to obtain a tissue diagnosis and to evaluate the stage of the disease and to ascertain the appropriate mode of therapy.

Progressive ptosis and headache developed in a 50-year-old woman with non-small cell lung cancer. Although brain magnetic resonance imaging showed improved cerebellar metastasis after prior radiotherapy without any other abnormality, the follow-up examination taken 6 months later revealed metastasis to the cavernous sinus. The diagnosis of metastasis to the cavernous sinus is often difficult because it is a very rare manifestation of lung cancer, and symptoms can occur prior to developing a radiologically detectable lesion. Therefore, when a strong clinical suspicion of cavernous sinus metastasis exists, thorough neurologic examination and serial brain imaging should be followed up to avoid overlooking the lesion.

Pulmonary giant cell carcinoma is one of the most highly malignant neoplasms of the lung. Although mixed malignant glandular or squamous components may be associated with a giant cell carcinoma, it is a distinct clinical and morphologic entity. We reviewed cytologic presentations of 6 cases of pulmonary giant ceil carcinoma. Cytologically, the single most characteristic feature of giant cell carcinoma was an extremely large, bizarre cancer cell engulfing numerous leukocytes. The nuclei of these cells showed occasional prominent nucleoli, and the cytoplasm was abundant. Giant cells were also seen in other types of pulmonary carcinoma, but the slant cells of this neoplasm could be differentiated from those encountered in undifferentiated large cell carcinoma and squamous cell carcinoma by the abundant cytoplasm, the presence of markedly enlarged nuclei, prominent nucleoli, and a significant degree of phagocytosis. In conclusion, precise diagnosis and classification of lung cancer is imperative because of proved correlation between cell type and prognosis.

Alveolar soft-part sarcoma is a rare soft tissue sarcoma of young adults with unknown histogenesis, and the organ most frequently involved in metastasis is the lung. We report the CT findings of three patients of pulmonary metastases of alveolar soft-part sarcoma, which manifested as clearly enhanced pulmonary nodules or masses. On enhanced scans, some of the masses were seen to contain dilated and tortuous intratumoral vessels.
