The lung is one of the most frequent sites of metastasis for extrathoracic tumors. Certain malignancies show a particular tendency to metastasize to lung, and in 15 to 25% of these cases, lung involvement is the only manifestation of metastatic disease. The most common presentation is the form of multiple bilateral nodules or masses of varying sizes. Lymphangitic metastasis is comprising 6 to 8% of all pulmonary metastasis. A striking variant of parenchymal involvement occures when dyscohesive tumor cells fill alveoli to produce a tumoral pneumonia. Carcinomatous lymphangitis of prostate origin is infrequent and usually carries a poor prognosis, and tumoral pneumonia of it is extremely rare. We report herein a case of prostate carcinoma metastasizing to lung, simulates atypical pneumonia, and disclosed by acute chest illness.

A 1-year and 8-month-old male, thoroughbred horse showed fever ($39.8^{\circ}C$), cardiac murmur, tachycardia up to 80 beats/min, anorexia, depression and lameness for about 2 months. The dead horse was referred to pathology laboratory at the College of Veterinary Medicine in Jeju National University. At necropsy, Severe protruding multiple rough cauliflower-like yellowish red nodules ranged $5{\sim}6{\times}2{\sim}3cm$ in size were attached on the mitral valve of the left heart. A yellowish red long stick-shaped thrombus $15{\times}3.5{\times}1.5cm$ in size was also present inside the right ventricle. Multifocal infarcts were scattered in the myocardium and renal cortex. Histopathologic examination revealed that morphologic diagnosis were vegetative endocarditis, thrombus in right ventricle, infarcts in myocardium and kidney, pulmonary congestion and edema, and splenic congestion. The isolated bacteria from vegetative lesions and thrombus were confirmed as Escherichia (E.) coli based on the bacterial culture and VITEK 2 system. Based on the gross and histopathologic features, and bacterial test, this case was diagnosed as vegetative endocarditis with thrombus formation associated by E. coli in a thoroughbred horse.

Von Recklinghausen`s neurofibromatosis, tuberous sclerosis and encephalotrigeminal angiomatosis[Sturge-Kalischer-Weber syndrome] are frequently classified under the heading of organic neurocutaneous syndromes. Both neurofibromatosis and tuberous sclerosis are believed to represent instances of simple autosomal dominant heredity. Multiple neurofibroma and cafe*-au-lait spots are the hallmarks of the van-Recklinghausen`s disease. The characteristic features of the fully developed syndrome are [1] pigmentation of the skin, including cafe*-au-lait spots, pigmented freckles and males, and occasionally a generalized darkening of the skin; [2] subcutaneous nodules and deep neurofibromatous tumors and diffuse plexiform growths of neural tissue; [3] skeletal anomalies, especially scoliosis; and [4] predilection to malignancy. In recent years cystic lung disease, usually of the so-called honeycomb lung variety, has been reported on several occasions in patients with tuberous sclerosis. This association has been shown to our sporadically as well as in members of a single family. Little attention has been paid to the presence of cystic lung disease in association with neurofibromatosis. Currently, most think of thoracic involvement in neurofibromatosis in terms of posterior mediastinal neuroma, pheochromocytoma, meningocele or, less commonly, parenchymal pulmonary neurofibromatosis. Author have experienced a case of von Recklinghausen`s disease. This case developed a huge neurofibroma in the both side thorax and invaded to the Lt. 7th rib.

Bronchiolitis interstitial pneumonitis (BIP), an unclassified and newly described interstitial pneumonia, has a combined feature of prominent bronchiolitis, interstitial inflammation, and fibrosis. It is distinct from bronchiolitis obliterans or bronchiolitis obliterans organizing pneumonia (BOOP). BIP has a better prognosis than common cases of interstitial pneumonia. However, BIP has a poorer prognosis than BOOP. BIP's response to corticosteroids is not as successful as BOOP's response to this treatment. We encountered the case of a 31-year-old woman with BIP with an initial presentation of dyspnea and a cough that had lasted for 3 months. The patient's chest CT scan demonstrated patchy ground glass opacities and multiple ill-defined centrilobular nodules in both lungs, suggesting military tuberculosis or nontuberculous mycobacterial infection. A video-assisted thoracoscopic lung biopsy resulted in the diagnosis of BIP. Clinical symptoms, pulmonary lesions, and pulmonary function tests were improved after oral glucocorticoid therapy.

Nontuberculous mycobacterial (NTM) diseases are increasing worldwide. However NTM lung disease in organ transplant recipients has been rarely reported. Here, we report 2 cases of NTM lung disease in heart transplant recipients. A 37-year-old man, who had undergone a heart transplant one year previous, was admitted to hospital due to a cough. Chest CT scan showed multiple centrilobular nodules in both lower lungs. In his sputum, M. abscessus was repeatedly identified by rpoB gene analysis. The patient improved after treatment with clarithromycin, imipenem, and amikacin. An additional patient, a 53-year-old woman who had undergone a heart transplant 4 years prior and who suffered from bronchiectasis, was admitted because of purulent sputum. The patient's chest CT scan revealed aggravated bronchiectasis; M. intracellulare was isolated repeatedly in her sputum. Treatment was successfully completed with clarithromycin, ethambutol, and ciprofloxacin. NTM lung disease should be considered as a potential opportunistic infection in organ transplant recipients.

Occupational lung diseases are caused by several toxic substances including heavy metals; however, the exact pathologic mechanisms remain unknown. In the workplace, dental technicians are often exposed to heavy metals such as cobalt, nickel, or beryllium and occasionally develop occupational lung diseases. We described a case of occupational lung disease in a patient who was employed as a dental technician for over a decade. A 31-year-old, non-smoking woman presented with productive cough and shortness of breath of several weeks duration. Chest computed tomography revealed a large number of scattered, bilateral small pulmonary nodules throughout the lung field, and multiple mediastinal lymph nodes enlargement. Percutaneous needle biopsy showed multifocal small granulomas with foreign body type giant cells suggestive of heavy metals inhalation. The patient's condition improved on simple avoidance strategy for several months. This case highlighted the importance of proper workplace safety.

양성 전이성 근종은 조직학적으로는 양성 종양의 소견을 보이는 자궁근종에서 폐로 전이되어, 임상적으로는 악성 종양의 성질을 지닌 매우 드문 질환이다. 저자들은 자궁근종으로 자궁 절제술을 계획하고 있는 환자에서 다발성 폐 결절이 발견되어, 폐절제술과 자궁절제술을 동시에 시행하였다. 수술후 조직병리 검사에서 폐 결절에서 호르몬 수용체 존재를 확인하여 양성 전이성 근종으로 확진할 수 있었으며, 환자는 수술 후 특별한 치료 없이 외래 추적 관찰 중이다.

A 13-year-old female Miniature Pincher was euthanized after suffering from respiratory insufficiency and seizure. At necropsy, firm tan masses approsimately 4 to 5 cm in diameter were noted at the right caudal love and left cranial lobe of the lung. On cross sections of the cerebellum and the verebrum, several compressive firm round masses, 0.5 to 1 cm in diameter, were noted. similar looking nodules were also present in the mediastinal lymph nodes. Histopathologically, the neoplastic masses consisted of cuboidal shape epithelial cells that form glandular structure. The neoplastic cells have hyperchromatic nuclei with prominent nucleoli and moderate amount of cytoplasm. The degree of mitosis was high (4-6/400X). Multiple areas of necrosis, hemorrhage, and tumor emboli were also noted. Metastasis to the mediastinal lymph nodes, pancreas, and brain was confirmed. Based on the gross and histopathologic examinations, a diagnosis of primary metastatic pulmonary adenocarcinoma was made. Clinicaly recognized neurological signs were therefore due to brain metastasis.

비행곤란을 나타내는 솔부엉이가 구조되어 충북대학교 동물의료센터에 의뢰되었다. 신체검사와 방사선 검사에서 좌측 상완골의 개방골절을 확인하였다. 3일 후 수내정과 와이어를 이용해 골절부 정복을 실시하였으나, 수술 후 2일 만에 급사하였다. 부검시 2~3 mm 크기의 녹색 결절이 왼쪽 폐의 표면과 내부에 다발성으로 발생하였다. 조직검사 결과 포자와 균사가 폐포에 다량 증식되고, 일부가 폐 실질에 침입하여 염증과 괴사를 유발하였다. 진균을 분리하여 Sabouraud dextrose 배지에 $30^{\circ}C$에서 7일간 배양한 결과, 청녹색의 밸벳 양상을 나타내는 곰팡이를 관찰하였다. ITS, ${\beta}$-tubulin 및 calmodulin 유전자를 증폭하여 동정한 결과 A. fumigatus로 확인되었다. 최종적으로 함기골 개방골절에 따른 이차적인 폐 아스퍼질러스증으로 사망한 것으로 진단하였다.
