Unilateral absence of a pulmonary artery (UAPA) is a rare congenital anomaly that is frequently associated with other cardiovascular anomalies first reported by Fraentzel in 1968. Most patients who have no associated cardiac anomalies have only minor or absent symptoms. We experienced a case of isolated UAPA in a young female presenting hemoptysis. The chest radiograph showed a small left lung volume and high resolutional CT of chest showed multiple subpleural nodules and centrilobular nodules in parenchyma. The video-assisted thoracoscopic biopsy revealed diffuse dilated vessels in visceral pleura. The pulmonary angiogram confirmed the absence of the left main pulmonary artery.

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.

Because a cavitary pulmonary metastasis is rare, it may not be readily identified. However, various types of cancers can metastasize to the lung in the form of cavities. We report a case of a multiple cavitary metastases to the lung from a cholangiocarcinoma in a 60-year-old man. He complained of generalized weakness and a poor oral intake for 2 months. The plain chest radiography and the chest computed tomography showed multiple small thick-walled cavities and nodules the both lungs. A bronchoscopic examination revealed a focal irregularly elevated surface of the mucosa at the orifice of the superior segment of the right lower lobe and the biopsy demonstrated an infiltrative metastatic adenocarcinoma. The abdomen-pelvis computed tomography showed an ill-marginated and irregularly low-dense area in the right lobe of the liver and a diffuse dilatation of the peripheral intrahepatic bile ducts. The esophagogastroscopy and colonoscopy showed no abnormal findings. It was concluded that the cholangiocarcinoma of the liver metastasized to the lung in the form of cavities. Thereafter, the patient underwent six cycles of the systemic chemotherapy with gemcitabine and cisplatin, and the follow-up imaging studies showed a partial response.

Cryptococcus neoformans is a ubiquitous fungus found worldwide, particularly in soil contaminated by pigeon drop- pings. Pulmonary cryptococcosis occurs rarely in immunocompetent individuals. The risk of cryptococcal infection increases with the degree of immunal compromise, in human immunodeficiency virus infection especially. Pulmonary cryptococcosis is most frequently encountered as asymptomatic single or multiple pulmonary nodules found by routine chest x-ray examination. The diagnosis is most often made in these situations by the histology of the resected lesion. Acute progressive pneumonia may occur, with symptoms of cough, sputum production, fever, and weakness. The clinical picture is not pathognomonic. The yeasts are stained well by any of the special stains for fungi. Treatment is now indicated for all cases given a diagnosis of cryptococcosis, even if the diagnosis has been made by resecton of a solitary, asymptomatic pulmonary nodule.

A 17-year-old female tiger (Panthera tigris altica) was found dead after suffering from continuously growing mass at the right mammary gland area. At necropsy, a firm tan mass approximately 25 cm in diameter was noted at the ventral abdomen. The mass was not fixed to the adjacent tissue and mottled tan to red on cut sections. Chains of similar nodules ranging from 2 to 5 cm in diameter were also present along the right mammary glands region. Histologically, the neoplastic masses consisted of lobules that were filled with pleomorphic neoplastic cells and separated by fibrious conntective tissue. The neoplastic cells have hyperchromatic nuclei with prominent nucleolus and moderate amount of cytoplasm. The degree of mitosis was high. Multiple areas of necrosis, hemorrhage, mineralization and tumor emboli were also noted. Metastasis to the regional lymph nodes, lung, liver, spleen, kidney, and adrenal gland were observed. Based on the gross and histopathologic examinations, a diagnosis of lobular type metastatic mammary gland carcinoma was made.

Although patients with breast cancer receive standard treatments, they often experience recurrence or metastasis of tumors. Therefore, patients seeking treatment with traditional Korean medicine (TKM) in addition to conventional treatment have increased. We present a case of 46-year-old female with recurring breast cancer. She underwent surgeries and various hormone therapies since being diagnosed in 2007. Upon follow-up examination, she had metastatic lesions on the lung and multiple bones in 2015 and 2016. She received TKM treatments from May 2017 with Aromasin and Afinitor. However, hepatic metastasis was found after two months, so she started Capecitabine with TKM. After about two months, the liver nodules disappeared and a seeding nodule in the right paracolic gutter was decreased. After two months, the tumor response was stable disease. Back pain due to bone metastasis was improved. We suggest that combination treatment of TKM and chemotherapy is a promising method for treating breast cancer.

The prevalence of pulmonary pargonimiasis in Korea has been steadily decreasing due to develop of the public health, and there have been few clinical cases of paragonimiasis infections, especially in pneumothorax. A 22-year-old man referred to emergency department for dyspnea and chest pain. The right lung was totally collapsed on a chest X-ray. We emergently performed a closed thoracostomy with a 28-Fr chest tube. However, the air leak from the chest tube persisted for three days after the closed thoracostomy. A chest computed tomography showed multiple subpleural consolidative nodular lesions and mixed ground-glass attenuation nodules. We potentially suspected a secondary pneumothorax resulting from pulmonary paragonimiasis infection because the patient was a Chinese man who was working at a Korean restaurant. We decided to perform a medical treatment instead of pulmonary wedge resections. The air leak was discontinued three days after the prescription of praziquantel. The patient was discharged nine days after the admission. We suggest that anti-parasitic drugs are very effective in the secondary pneumothorax resulting from paragonimiasis.

An 8-month-old ostrich (Struthio camelus) which had shown lethargy died in 2-day clinical course. Gross necropsy revealed greenish gray mold grow on the wall of thickened air sacs and multiple tiny nodules on the liver. Microscopically, the granulomatous lesions of air sac membrane, lung, and liver contained numerous septate, branching fungal hyphae. The typical conidial heads of fungi were observed in inner membrane of inflammatry thickened air sacs. This case was a chronic and systemic mycotic air sacculitis and pneumonitis caused by Aspergillus fumigatus in a ostrich at a zoo.

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.

Most cases of eosinophilic pneumonia reported previously have followed a chronic course. The case presented here was acute in onset, suggesting a acute eosinophilic pneumonia. A model of criteria for acute and chronic eosinophilic pneumonia was made by Umeki in 1992. A previously healthy young man presented with cough, sputum, fever, and multiple small nodules on the chest radiograph. We confirmed eosinophilic pneumonia with bronchoalveolar lavage analysis and transbronchial lung biopsy. This case examplifies the recently descrived acute eosinophilic pneumonia.
