Bronchioloalveolar carcinoma is originated from the periphery of the lung and can be mistaken for lobar pneumonia or atypical pneumonia clinically and at gross examination. Recently the authors experienced a 67-year-old woman who had slowly progressed pulmonary lesions for four years. At first, she visited this hospital for intermittent chest pain four years before. And she visited other hospitals for the same problem and had a series of evaluation including two times of biopsy but did not have any conclusive diagnosis. With aggravation of chest pain, she was referred to this hospital again and the lesion was reexamined and confirmed as bronchioloalveolar carcinoma by ultrasonography-guided needle biopsy. Being performed left lower lobectomy, she kept good condition without any complication.

The pneumonic lungs of 51 pigs, from which the presence of pasteurella organisms was confirmed by bipolar staining, were examined pathologically. The numbers of pigs in each age group were 22 (43.1%) in 3-4 month group, 20 (39.2%) in 1-2 month group, 7 (13.7%) in 5-6 month group, and 2 (4.0%) in group of more than one year. The lungs of 16 pigs which were regarded as pasteurella pneumonia without any other manifestations were studied pathogically. Grossly, the affected lungs showed pulmonary edema, lobular consolidation and interlobular edema. Pigs over 3 months of age frequently showed chronic condition in which the entire lobe was involved as confluent pneumonia. In such pneumonic lungs, infarction and focal necrosis of the lung parenchyma and deposition of fibrinous exudate on the pleura were encountered. Histologically, the alveolar spaces were filled with fibrinous and leukocytic exudates. The interlobular septae showed marked edema and fibrinous exudate. The process of organization was frequently observed in chronic cases.

Bronchioloalveolar cell carcinoma accounts for less than 6% of all primary lung cancer but has distinct clinical and radiological features and unusual pathologic appearance. The characteristic features are its peripheral location and tendency of rapid progression to diffuse type via aeroginous and lymphatic route without surgical intervention. Among them, mucin secretory type bronchioloalveolar cell carcinoma is the rarest and most distinctive. We experienced a case of mucin secretory type bronchioloalveolar cell carcinoma in a 47 year old female with roentgenographic findings of chronic progressive pulmonary consolidation with muliple cavities.

Enzootic pneumonia caused by Mycoplasma hyopneumoniae is responsible for major economic losses in pig herds of world wide. Mycoplasma hyopneumoniae can also act as a primary pathogen of porcine respiratory disease complex followed by bacterial or viral infection. This study was carried out to investigate the prevalence of mycoplasmal pneumonia of slaughtered pigs in Jeju for two years. The lungs and sera of 214 cases were examined for gross and microscopic lesions of the lungs, immunohistichemistry test for Mycoplasma hyopneumoniae antigen and enzyme-linked immunohistichemistry assay (ELISA) for serum antibody titer. Pulmonary consolidation was observed in the lungs of 163 pigs $(76.1\%)$ with average gross lesion score of $6.0\%$., Bronchointerstitial pneumonia was most frequently observed $(78.5\%)$. The incidence of pulmonary consolidation was decreased in vaccinated pigs compared to that of non-vaccinated pigs. The rate of consolidation in the lungs was significantly decreased in the vaccinated pigs (P<0.05). Antigen of Mycoplasma hyopneumoniae was identified by immunohistichemistry test in the lungs of 174 pigs $(81.3\%)$. ELISh antibodies to Mycoplasma hyopneumoniae were detected in 154 pigs $(72.0\%)$. These results showed the prevalence of swine pneumonia and the incidence of Mycoplasma hyopneumoniae in slaughtered pigs of Jeiu province. We expect that these results would be helpful for the control of swine mycoplasmal pneumonia and porcine respiratory disease complex in Jeju.

We present a rare case of critically compromised airway secondary to a massively dilated sequestered colon conduit after several revision surgeries. A 71-year-old male patient had several operations after the diagnosis of gastric cancer. After initial treatment of pneumonia in the pulmonology department, he was transferred to the surgery department for feeding jejunostomy because of recurrent aspiration. However, he had respiratory failure requiring mechanical ventilation. The chest computed tomography (CT) scan showed pneumonic consolidation at both lower lungs and massive dilatation of the substernal interposed colon compressing the trachea. The dilated interposed colon was originated from the right colon, which was sequestered after the recent esophageal reconstruction with left colon interposition resulting blind pouch at both ends. It was treated with CT-guided pigtail catheter drainage via right supraclavicular route, which was left in place for 2 weeks, and then removed. The patient remained well clinically, and was discharged home.

A 59-year-old man presented with acute dyspnea following sudden productive cough and expectoration of a full cup of "blood-tinged" sputum. He had been diagnosed with hepatitis B virus-related hepatocellular carcinoma and had received transarterial chemoembolization 5 years ago for a 20-cm hepatic mass; he denied any history of hematemesis and the last esophagogastroduodenoscopy from a year ago showed absence of varix. Chest computed tomography (CT) with angiography showed new appearance of right basal lung consolidation but no bleeding focus. Despite the use of systemic antibiotics, the patient developed respiratory failure on day 7 of hospitalization. After intubation, a massive amount of brown sputum with anchovy-paste-like consistency was suctioned via the endotracheal tube. Bronchoscopic toileting was performed and the patient was extubated. In the ward, he continued to expectorate the brown sputum. On day 25 of hospitalization, a repeat CT scan showed simultaneous disappearance of the pneumonic consolidation and the necrotic fluid within the hepatic mass, suggesting the presence of a fistula. He has continued to receive systemic antibiotics, sorafenib, and entecavir, and follow up by respiratory and hepato-oncology specialists.

Four 5 month old calves were died after showing respiratory distress after long-distance transportation at winter season. They were diagnosed as fibrinous lobar pneumonia caused by Mannheimia (M.) haemolytica. Grossly, lungs were attached onto the pleura by fibrin, with a rich yellowish fluid in thorax. The cut surface of the lung was showed marbled pattern of the reddish or greyish consolidation and widened interlobular septa by fibrin deposition. Histopathologically, parenchymal necrosis was delineated by a band of the degenerated inflammatory cells, and distended interlobular septa with serofibrinous exudates and vascular thrombosis with alveolar capillaries degeneration and abundant serofibrinous exudates in alveoli. M. hemolytica were isolated from all calves, and bovine viral diarrhea virus and parainfluenza type 3 virus in one calf were detected by RT-PCR. Thus, it was concluded that this case was diagnosed as pneumonic mannheimiosis suggested by complex infection with viruses after long-distance transportation and coldness.

Hemolytic anemia due to cold agglutinin disease is a known complication of Mycoplasma pneumoniae infection but is rarely observed, particularly in children. A case of Mycoplasma pneumonia complicated with hemolytic anemia is presented. A 7 year-old girl was adimitted because of fever, cough, sputum and pale appearance. Chest X-ray showed pneumonic consolidation of Rt. upper lobe, lingular division. Laboratory studies disclosed the following values : Hb 5.3g/dL, Hct 11.1%, reticulocyte 2.9%, indirect Coombs test negative, direct Coombs test(monovalent) Anti-C3d positive, Anti-IgG negative, Anti-IgM negative, cold agglutinin titer 1 : 256, mycoplasma antibody titer 1 : 640, total bilirubin 1.0mg/dL. Initial PBS before wanning showed agglutination of red blood cells. The diagnosis of cold agglutinin hemolytic anemia complicating mycoplasma pneumonia was made. And treatment with roxithromycin, prednisolone and avoiding cold exposure was initiated, and complete recovery ensued. We report a case of cold agglutinin hemolytic anemia complicating mycoplasma pneumonia in children.

A chest x-ray of 68 year old male showed pneumonic consolidation of right lower lung field with blunting of right cardiac border. Computerized tomography of chest revealed infiltrative mass with V-shaped calcification just below right main bronchus. This finding has to be made into differential diagnosis of numerous pulmonary diseases including, mycobacterial disease, neoplasm, lymphadenopathies, and foreign bodies. Initial bronchoscopic findings suggest endobronchial mass lesion on right intermediate bronchus but endobronchial biopsy fail to prove malignant cell or underlying illness. But repeated endobronchial biopsy shows metallic material in the right Intermediate bronchus and we remove it with alligator jaws forcep under bronchoscopy. He was well after discharge.
