Nasotracheal intubation is performed routinely in maxillofacial surgery to optimize visualization of the surgical field. The CaldwellLuc operation is an approach to the maxillary sinus through the labiogingival sulcus and canine fossa. The operation is used to treat chronic maxillary sinusitis, and involves curettage of the mucosa of the maxillary sinus and the creation of an inferior meatal antrostomy. After the operation, a nasal Foley catheter is inserted into the inferior nasal meatus for the discharge of blood and tissue fluid. Then, the nostril is packed with vaseline gauze. Before the patients awaken, they experience impaired switching from nasal to oral breathing. Pulmonary edema can result from excessive negative intrathoracic pressure caused by acute airway obstruction in patients breathing spontaneously. During anesthesia and sedation, airway obstruction can occur at the levels of the pharynx and larynx. Even in patients who are awake, alteration in the ability to change the breathing route from nasal to oral may affect breathing in the presence of an airway obstruction, causing this catastrophic event. We experienced a case in which acute pulmonary edema resulted from acute airway obstruction triggered by the patient's inability to switch the breathing route from nasal to oral during emergence from anesthesia.

A 10-year-old intact female Yorkshire terrier dog (weighing 3 kg) was referred with the primary complaint of severe dyspnea, cyanosis and occasional syncopal episode. Physical examination revealed irregularly irregular bradycardia with persistent pulse deficits. The 12-lead surface ECG showed high grade atrioventricular blocks. Thoracic radiography revealed severe intrathoracic collapse. The dog was successfully treated with an intraluminal self-expanding stent ($COOK^{(R)}$) under the aid of transcutaneous cardiac pacing.

Intrathoracic involvement of immunoglobulin G4 (IgG4)-related disease has recently been reported. However, a subset of the disease presenting as interstitial lung disease is rare. Here, we report a case of a 35-year-old man with IgG4-related lung disease with manifestations similar to those of interstitial lung disease. Chest computed tomography showed diffuse ground glass opacities and rapidly progressive pleural and subpleural fibrosis in both upper lobes. Histological findings showed diffuse interstitial lymphoplasmacytic infiltration with an increased number of IgG4-positive plasma cells. Serum levels of IgG and IgG4 were also increased. The patient was diagnosed with IgG4-related lung disease, treated with anti-inflammatory agents, and showed improvement. Lung involvement of IgG4-related disease can present as interstitial lung disease and, therefore, should be differentiated when evaluating interstitial lung disease.

Progressive dysphagia in a 53 year old man was caused by a giant polypoid tumor in the lower intrathoracic esophagus. Radical transthoracic esophagectomy and esophagogastrostomy were carried out. Microscopic examination of the tumor revealed a true carcinosarcoma, composed of a mixture of basaloid squamous cell carcinoma and chondrosarcoma with multiple cartilagenous productions. Carcinoma metastases were found in the subcarinal and perigastric lymph nodes. Immunohistochemically, squamous area displayed strong positive to cytokeratin, and basaloid area showed positive immunoreaction to high molecular weight cytokeratin (34${\beta}$E12). Spindle cell sarcoma reacted to vimentin and smooth muscle actin. Chondrosarcomatous area reacted to vimentin and S-100 protein. He received postoperative chemotherpy and radiotherapy. He has been free of disease for 11 months.

Migration of Steinmann pins into the thoracic cavity is uncommon, but when occurs it can bring devasting consequences. A Sixty-year-old woman had pinning of the right humerus surgical neck fracture. She was not followed up after discharge Two years later, a chest x-ray film and chest CT showed that the pin had migrated to the right hemithorax. The migrated pins were removed with right anterolateral thoracotomy incision without any difficulties.

Partial splitting of the upper sternum provides an excellent surgical view in reconstruction of the intrathoracic trachea. However, when deep-seated mediastinitis develops postoperatively, it is difficult to manage especially when combined with sternal osteomyelitis. It also needs an additional consideration compared to the usual treatment modality applied to mediastinitis following a standard median stemotomy because the lower part of the stemum remains intact. We treated a 50 year old female patient with deep-seated mediastinitis and sternal osteomyelitis following resection and end-to-end anastomosis of the trachea through an upper midline sternotomy. The patient underwent extensive stemectomy, omental free grafting, and pectoral myocutaneous flap. Postoperative viability of the free-grafted omentum was evaluated by angiography and CT scan.

A nine-year-old neutered male cat was presented with chronic cough and vomiting. Thoracic radiography showed regions of fatty opacity in the right caudoventral region. On positive contrast celiography, contrast agent did not move into thoracic cavity. Computed tomography revealed 7-mm diameter of defect at the right diaphragmatic crus and a 2-mm diameter defect at the left ventral diaphragmatic crus. Through the right diaphragmatic defect omental herniation was confirmed by the presence of contrast enhanced omental vessel running across the diaphragm. On exploratory thoracotomy, the omentum protruded into the thorax through the right diaphragmatic defect, and it contained a yellowish lipomatous mass. The protruded omentum containing a mass in the thorax was removed, and the right diaphragmatic defect was closed. Histopathologic examination revealed that the protruded omentum showed normal omental structure and the adipose mass showed lipoma surrounded by fibrous tissue. In conclusion, a thorough examination is necessary to confirm the origin of the mass located near the diaphragm.

Diaphragmatic hernias have been reported in 0.8%-1.6% of patients who experience blunt chest trauma. The hernia is assumed to form as a result of direct diaphragmatic violation or significant intraabdominal or intrathoracic pressure caused by the trauma. Some reports have described cases of delayed diaphragmatic hernia and subsequent stomach perforation that occurred a few days to several years after an accident. We report an extremely rare case of diaphragmatic herniation in which the process from initial blunt trauma to visceral organ perforation took only 2 days, without any evidence of herniation on the initial X-ray or computed tomography. Delayed diaphragmatic herniation and subsequent visceral organ perforation should not be missed during the period immediately after blunt chest trauma.

Mature fetiform teratoma, or homunculus, is a term coined for a rare variant of teratoma with a prevalence of 0.01% of teratomas. There have been very few cases reported in the world, and its thoracic presentation is extremely unusual. We present the case of a 31-year-old female patient with a history of progressive chest pain in the left hemithorax, associated with dyspnea on moderate exertion and cough. Imaging studies revealed a large intrathoracic tumor visually compatible with a teratoma. Surgical resection by a clamshell approach was successful, and subsequent anatomopathological studies of the operative specimen concluded that the mass was a mature fetiform thoracic teratoma. The treatment of this entity is generally surgical and includes wide resection due to its large adhesive component to surrounding tissues. Thus, the cardiothoracic surgeon must know approaches that allow wide resection, making these cases true surgical challenges.

Hypertrophic osteoarthropathy (HOA) is a syndrome characterized by digital clubbing, periosteal bone formation, and synovial effusions. Secondary HOA is associated with intrathoracic malignancy in most cases; however, in rare cases, HOA can be caused by extrathoracic conditions. We report early ultrasound, computed tomography, magnetic resonance imaging, and bone scintigraphy findings of HOA in a patient with breast cancer. Its ambiguous clinical and imaging findings that mimicked malignant conditions are particularly interesting and informative.
