Tuberculosis is one of the most common chronic disease. While the disease process may involve anywhere of the body, tuberculosis of anterior mediastinum which forming tumor like mass was not recognized commonly. We experienced a surgical case of tuberculous empyema thoracis at anterior mediastinum in 16 year old boy. Preoperatively, he was diagnosed to anterior mediastinal tumor such as teratoma or dermoid cyst by routine study. Operation was performed by midline sternotomy extending over right 4th intercostal space. The mass was elongated football shaped [20x16x15] and markedly adhered to right side of pericardium, upper 8< lower lobe of the right lung. Opening the mass, enormous pus-like material was evacuated and excised segmentally with decortication. Postoperative pathologic diagnosis was tuberculous empyema thoracis and granuloma.

Histopathological changes in the pancreas of bovine eurytremiasis were dilatation and thickning of the pancreatic ducts inwhich infiltration of eosinophils and lymphocytes was prominent. The mucous epithelium showed papilliferous and adenomatoid hyperplasia. Proliferation of tissue mast cells in the mucosa propria of the pancreatic ducts was recognized. In addition, granulomatous inflammation was accompanied with the death of Eurytrema in the pancreatic ducts. Granuloma formation around Eurytrema eggs which were embolized in the lung of rabbit was observed on 15 and 20 days after injection.

A case of aspergillosis in 39-day-old layer chickens having a history of gradual emaciation and subsequently death with nervous signs such as torticollis and lack of equilibrium was documented. Based on the results from serology and polymerase chain reaction (PCR) test, this flock was not affected with known viral or bacterial diseases. On postmortem examination of the affected birds, multiple white to yellow nodules measuring 1~5 mm in diameter were observed in the lungs, cerebrum, liver and kidney. Microscopically, these nodules were identified as granulomatous lesions characterized by mixed population of multinucleated giant cells and lymphocytes. By periodic acid-schiff staining and nucleotide sequencing analysis, Aspergillus flavus with characteristic septate and branched hyphae were identified in the granuloma of lung and cerebrum. This case was a chronic and multisystemic aspergillosis specialized to central nervous system caused by Aspergillus flavus infection in the layer flocks.

We have experienced a case of sarcoidosis appearing asymmetrical diffuse interstitial lung lesions with multiple lymphadenopathy. This patient was a 57 year-old female who had been in good health until 2 months ago. At that time she noted the onset of an exertional dyspnea and weakness. Pulmonary function tests showed moderate obstructive pattern with mild decreased DLco. In the chest CT, multiple lymphadenopathy with small nodular lesions are scattered, and the impression was a metastatic lymph nodes with lymphangitic carcinomatosis. In bronchofiberscopy, we noted luminal narrowing by extrinsic compression in the right middle and lower lobe bronchi. And microscopic examination of by bronchofiberscopic biopsy showed chronic inflammation. Thus we performed subcarinal and tight supraclaviclar lymph nodes aspiration biopsy cytology, and that revealed class 0 and class 1, respectively. Finally, we performed an excisional biopsy for the right scalene lymph node, which revealed the specimen as a noncaseating granuloma. The angiotensin convecting enzyme level was overt two folds compared to normal value. And the patient had negative PPD skin test and hyperglobulinemia. After 18 weeks treatment with prednisone, the signs and symptoms which the patient clad suffered from, disappeared.

Pulmonary toxicity of talc containing tremolite asbestos (TCT) has been studied in term sequential in Sprague-Dawely rats. UICC chrysotile(average diameter 0.03${\mu}m$, average length 2.93${\mu}m$) was applied as the positive control. TCT was analyzed for its physicochemical properties by transmission electron microscope equipped with energy dispersive X-ray spectrometer(TEM-EDS). The effects of 2mg TCT(talc average diameter 9.7${\pm}$8.4${\mu}m$; tremolite average diameter 1.6${\pm}$1.6${\mu}m$, average length 10.8${\pm}$7.0${\mu}m$) on pathological changes were evaluated after 1, 8 weeks instilled into rat lungs. 2mg Chrysotile continuously affected lung pathological changes. Inflammation and granuloma response broke out from 1 week after instilled with chrysotile and the pathological examination further showed increased legions of lung after 8 weeks. But TCT did not showed lung pathological changes. The biopersistence of TCT and chrysotile was evaluated by TEM- EDS. Whereas chrysotile continuously have retained to 8 weeks instilled into rat lungs, talc of TCT showed statistically significant decrease of diameter from 1 weeks and statistically significant change in Si atomic % compositions at 8 weeks instilled into rat lungs. Physicochemical properties of tremolite of TCT were not affected until 8 weeks instilled into rat lungs. This study showed that the durability of TCT in the lungs is much weaker than chrysotile.

Castleman's disease is uncommon lymphoproliferative disorder as giant lymph node hyperplasia and angiofollicular lymph node hyperplasia. Multicentric variant of Castleman's disease, plasma cell type has been described that has more generalized lymph node involvement as well as involvement of other organ systems than localized type. Multicentric plasma cell type is frequently accompanied by systemic manifestations, such as weight loss, lowgrade fever and weakness. But the reported cases of pulmonary parenchymal involvement are rare and have almost consisted of hyalinized granuloma adjacent to a bronchus. We report a patient with Castleman's disease of the lung, pathologically proven interstitial pulmonary involvement.

Dogs were divided into 3 groups of two each; Bacillie Calmette-Guerin(BCG) pretreatment, M bovis only treatment and uninfected control group. BCG were vaccinated intradermally with 0.2ml before 3weeks of M bovis intraperitoneal infection. Infection at necropsy 4months later was readily in the both treated dogs. Histopathologically, the BCG pretreated dogs produce the moderate accumulation of macrophages and focal granuloma formation in the lung, whereas the M bovis only treared dogs produce the accumulation of predominantly macrophages, occasionaly polymorphonuclear cells and the more larger granuloma Bronchoalveolar lavage(BAL) was obtained and total and differential cell counts were examined. Total number of BAL cells harvested from uninfected dogs is lower compared with those of the both treated groups. The total cell number of M bovis only treated dogs were singificantly higher 1.8 times than that of the BCG pretreated dogs. The Fe receptor activity and the growth of organism in alveolar macrophages obtained from BCG pretreated dogs were compared with that in macrophages from M bovis only treated dogs. BCG vaccination resulted in substantial macrophage activation, measured as increased Fc receptor mediated phagocytosis and rosette formation, as wells as the inhibition of intracellular mycobacteria multiplication. However, actibated macrophages taken from BCG pretreated dogs are incapable of killing the M bovis. Thus, these results suggest that BCG pretrearment in the dog may produce a protective effect against tuberculosis because active alveolar macrophages have acquired antituberculous immunity, although few mycobacteria within the lung remain in a metabolically active state.

Adalimumab is a full human monoclonal antibody that inhibits tumor necrosis factor-alpha (TNF-${\alpha}$). This has recently been shown to be effective in the treatment of rheumatoid arthritis (RA), ankylosing spondylitis, and other conditions. Sacoidosis is known to be the target for adalimumab but we describe a patient who has developed sarcoidosis with lung involvement during adalimumab therapy for RA. A 48-year-old woman, who was treated with adalimumab for 5 months, was admitted because of chronic cough and both hilar lymphadenopathy on chest radiography. Chest computed tomography revealed the enlargement of multiple lymph nodes in the right supraclavicular, subcarinal, both hilar and right axillary area. She was diagnosed with sarcoidosis based on the biopsy of supraclavicular lymph node, skin and lung through video-associated thoracoscopic surgery, which was non-caseating epitheloid cell granuloma and excluded from a similar disease. She was treated for sarcoidosis with prednisolone and methotrexate instead of adalimumab.

Sarcoidosis is a multi-systemic granulomatous disorder of unknown etiology. The characteristic pathological finding is the presence of non-caseating granulomas. The lungs are primarily affected, however other organs may be involved causing various symptoms and ambiguous laboratory findings can be present. There are a few reported cases of sarcoidosis with elevated tumor markers. We describe a 68-year-old woman presenting with sarcoidosis showing elevated serum carcinoembryonic antigen (CEA). The possibility of cancer arising from serum CEA such as gastrointestinal cancer, breast cancer and lung cancer was excluded. A transbronchial lung biopsy demonstrated a non-caseating granuloma without necrosis. As a result prescribed 30 mg prednisolone daily to the patient and serum CEA was decreased after 1 month of treatment. We report a case of pulmonary sarcoidosis with elevated serum CEA.

Sarcoidosis can affect two or more members of the same family, and the reported occurrence of such familial sarcoidosis is variable from 0.5 to 14%. Recent1y we have experienced familial sarcoidosis affected mother and daughter, for the first time in Korea. Mother was diagnosed as Stage 11 sarcoidosis 4 years ago by transbronchial lung biopsy and cervical lymph node biopsy with compatible BAL finding in our hospital. This time, the daughter was admitted with bilateral hilar enlargement and anterior uveitis. Even though she had positive tuberculin skin test and atypical BAL finding(lymphocyte: 61%, CD4/CD8: 1.22). Transbronchial lung biopsy and mediastinal lymph node biopsy revealed noncaseating epithelioid granuloma without AFB. Slit lamp examination of the eyes showed severe anterior uveitis. Systemic steroid therapy was started due to progressive uveitis with antituberculous medication.
