Inflammatory myofibroblastic tumor (IMT), normally referred to as inflammatory pseudotumor, is a fairly rare condition. Fine needle aspiration cytology (FNAC) of IMT has only rarely been reported. Here, we describe one such case of pulmonary inflammatory myofibroblastic tumor. A 30-year-old man presented with a 2.8cm-sized mass in his lung. Chest CT revealed a well defined, poorly enhancing mass. FNAC showed some fascicular or swirled clusters of spindle cells, admixed with occasional inflammatory cells and foamy histiocytes. The majority of the tumor cells evidenced bland, elongated nuclei, but infrequent pleomorphic nuclei. Some of the tumor cells evidenced nuclear grooves and intranuclear inclusions. Although the cytological differentiation of IMT from malignant lesions is not immensely problematic, due to the general paucity of cytological and nuclear atypia, a definite cytological diagnosis of IMT cannot be rendered simply by FNAC. Therefore, a diagnosis of IMT may be suggested via exclusive diagnosis.

The bronchopulmonary sequestration is a region of the lung parenchyma that has an incomplete or no connection with the airways and is supplied by an aberrant artery arising from the aorta or one of its branches. The anatomy of the supplying artery is very important during operation. A case of pulmonary sequestration supplied with the left gastric artery is presented. The patient was 61 years old male and had hemoptysis. The chest CT showed cystic bronchiectasis in the left lower lung with few air-fluid level. Also, in aortogram, arterial supply was The aortogram also showed arterial supply coming from the left gastric artery of abdominal aorta branches. Left lower lobectomy and abnormal arterial ligation were performed.

Poncet's disease is an aseptic polyarthritis developing in the presence of active Tuberculosis occurring elsewhere, and is not due to direct involvement of joints but to an immunological reaction to tuberculoprotein. We experienced a case of Poncet's disease accompanying erythema nodosum in a 55-year-old female patient with pulmonary tuberculosis. She had multiple tender erythematous nodules on both lower limbs for 3 months and a cough and sputum from one month ago. She felt severe pain in both knees and ankles with swelling one week before admission. Her chest X-ray, computed tomography (CT) scan and positive sputum AFB stain results revealed that she had active pulmonary tuberculosis accompanying erythema nodosum and aseptic polyarthritis. Her arthritis and erythema nodosum were dramatically improved within four weeks after anti-tuberculosis therapy. We report a case of Poncet's disease in pulmonary tuberculosis accompanying erythema nodosum.

Respiratory bronchiolitis-associated interstitial lung disease is one of the smoking-related interstitial lung diseases. Histopathologically, it shows respiratory bronchiolitis, which is characterized by the accumulation of pigmented macrophages within the respiratory bronchioles, accompanying peribronchiolar inflammation. Clinically, it is presented with respiratory symptoms such as a cough, sputum and dyspnea on exertion. It is well known that the incidence of malignancy in interstitial lung disease is high, but in respiratory bronchiolitis-associated interstitial lung disease the report of accompanying malignancy is rare. Here we report a case of a 60-year-old male heavy smoker presented with a cough, sputum and clubbing finger. A chest computed tomography (CT) of the patient did not show any shadow suspected of malignancy, but adenocarcinoma was found on a transbronchial lung biopsy and on a surgical lung biopsy with respiratory bronchiolitis-associated interstitial lung disease.

A factor VII gene -401 G/A polymorphism was identified in a patient with a pulmonary embolism. The patient was a 71-year-old woman who presented with acute-onset dyspnea. A chest CT scan revealed a pulmonary embolism. Despite the administration of low-dose warfarin as anticoagulation therapy, there was an excessively prolonged prothrombin time (PT). The blood tests revealed lower factor VII activity than normal. Full factor VII gene sequencing revealed a G to A substitution at -401 in the promoter region. There were no other gene sequence anomalies. PCR-based analysis indicated lower factor VII gene expression in the patient than in a control subject. The data suggested the promoter polymorphism to be responsible for the lower transcription level. In conclusion, we encountered a case of Factor VII DNA polymorphism in a patient with a pulmonary embolism showing significantly reduced Factor VII activity.

Copper sulfate is a copper compound used widely in the chemical and agriculture industries. Most intoxication occurs in developing countries of Southeast Asia particularly India, but rarely occurs in Western countries. The early symptoms of intoxication are nausea, vomiting, diarrhea, and abdominal cramps, and the most distinguishable clue is bluish vomiting. The clinical signs of copper sulfate intoxication can vary according to the amount ingested. A 75-year old man came to our emergency room because he had taken approximately 250 ml copper sulfate per oral. His Glasgow Coma Scale (GCS) score was 14 and vital signs were blood pressure 173/111 mmHg, pulse rate 24 bpm, respiration rate 24 bpm, and body temperature $36.1^{\circ}$ .... Arterial blood gas analysis (ABGa) showed mild hypoxemia and just improved after 2 L/min oxygen supply via nasal cannula. Other laboratory tests and chest CT scan showed no clinical significance. Three hours later, the patient's mental status showed sudden deterioration (GCS 11), and ABGa showed hypercarbia. He was arrested and his spontaneous circulation returned after 8 minutes CPR. However, 22 minutes later, he was arrested again and returned after 3 minutes CPR. The family did not want additional resuscitation, so that he died 5 hours after ED visit. In my knowledge, early deaths are the consequence of shock, while late mortality is related to renal and hepatic failure. However, as this case shows, consideration of early definite airway preservation is reasonable in a case of supposed copper sulfate intoxication, because the patients can show rapid deterioration even when serious clinical manifestation are not presented initially.

Malignant melanoma develops from the melanocyte and the most common primary site is skin, followed by mucosa and retina. Even though any other tissue where melanocytes reside could be the primary site of the malignant melanoma, the one developed in the mediastinum is rarely reported. We experienced a patients of 54 years old woman whose initial symptom was progressive dyspnea for one month, and proved to have the anterior mediastinal mass with pleural effusion and the small mass in the abdominal soft tissue. The needle aspiration biopsy from the mediastinal mass showed the consistent findings with malignant melanoma. We concluded the mediastinum was the primary site of the malignant melanoma of this patient because we couldn't find any other evidence of primary tumor in skin, oral and gastrointestinal mucosa, and retina. She has been treated with combined chemotherapy with dacarbazine, cisplatin and vinblastine. Her symptom was improved after chemotherapy and follow up chest CT after three cycles of chemotherapy showed the decreased tumor size in the mediastinum.

We report a case of hepatopulmonary syndrome defined as a triad of chronic liver disease, increased alveolar oxygen gradient on room air, and intrapulmonary arteriovenous shunting. Chest rediographs showed bilateral, basilar, medium sized reticulonodular opacities. High resolution CT scand showed multiple centrilobular nodules and branching structures in the subpleural lung that suggested dilatation of lung vessels with abnormally large number of visible terminal branches. $^{99m}Tc$-macroaggregated albumin(MAA) perfusion lung scan showed right to left shunt. Contrast echocardiography demonstrated intrapulmonary vascular shunt without intracardiac shunt.

A 73-year-old man who had undergone a right pneumonectomy and open window thoracostomy due to tuberculous empyema, presented with purulent discharge from the previous operation site. The computed tomography of the chest showed diffuse pleural thickening and a low attenuated lesion, with air bubbles in a dependent portion of the right hemithorax. These air bubbles were revealed to be due to 7 pieces of retained surgical gauze by flexible bronchoscopy. The patient showed marked clinical improvement with diminished purulent discharge after removal of the foreign bodies.

Tuberous sclerosis (TS) is an autosomal dominant disorder that is characterized by cutaneous lesions, seizures, mental retardation and hamartomas in various organs including the skin, kidney and brain. Pulmonary involvement is extremely rare, and occurs in approximately 0.1 to 1% of TS cases. Recent reports have indicated multiple micronodular pneumocyte hyperplasia (MMPH) as another rare form of pulmonary involvement of tuberous sclerosis. We report a case of a 35 year-old-male patient who had no pulmonary symptoms but showed multinodular pulmonary shadows on his chest CT scan. The patient was finally diagnosed with TS with MMPH of the lung. MMPH does not appear to have any malignant potential but the clinical significance of MMPH in TS patients is unknown.
