Background: Pulmonary hamartomas are the most common form of pulmonary benign tumors, and they occur in approximately $2{\sim}5%$ of all pulmonary neoplasm. However, only a few reports have been published on the clinical characteristics of pulmonary hamartoma in Korea. Material and Method: The charts, X-rays and pathological specimens of 37 pulmonary hamartoma patients who were diagnosed by a pathological examination from January of 2000 to May of 2005 at the Catholic Medical Center were retrospectively reviewed. Result: The peak incidence of the tumor occurred in the seventh decade of life (32.4%), There were 23 men (62.6%) and 14 women (37.8%), with mean age of 55.6 years. Twenty-six patients (70.3%) were asymptomatic and 11 patients (29.7%) had symptoms. A total of 29 tumors (78.4%) were parenchymal, and 8 (21.6%) were endobronchial. Twenty cases (54.1%) were in the right lung and 17 cases (45.9%) were in the left lung. The right lower lobe was most commonly involved. Thirty-two (86.5%) hamartomas were diagnosed by surgical resection, 4 cases (10.8%) were diagnosed by bronchoscopic biopsy and 1 case (2.7%) was diagnosed by a fine needle aspiration biopsy. Thirty-four hamartomas (91.9%) were managed by surgical resection without complication. No recurrence or malignant changes were seen during the follow up period. Conclusion: Pulmonary hamartomas are most common in males during their fifth to seventh decade and they more commonly involve the right lung. No recurrence or malignant changes were seen during the follow up period.

Primary leiomyosarcomas are rare tumors of the lungs. No typical roentgenographic findings of unusual complex of symptoms distinguish this tumor. The most common therapy is surgical resection. Prognosis and significant survivorship are related to the size, grade, metastasis of the lesion. A 25-year-old female patient with chest pain and cough was admitted. In chest X-ray and CT scan, there was a pulmonary nodule in left upper lung field, She was taken a percutaneous needle aspiration biopsy. The result was a spindle cell tumor. Left upper lobe lobectomy was done, and pathologic diagnosis was a low grade leiomyosarcoma arising from left bronchus. During 5 years of follow-up period, she has not shown any metastasis or local recurrence.

Aspergillus Infection is a major.cause of mortality in individuals with depressed cell-mediated immunity. Despite therapy with intravenous amphotericin B and oral antifungal agents, high mortality has been reported among heart transplant recipients. We experienced two cases of pulmonary aspergillosis among 15 heart transplantation cases. Both cases were similiar in terms of age, time of diagnosis, and medication. Percutaneous needle aspiration biopsy revealed Aspergillus fumigatus in both cases. The thirst case showed multiple aspergilloma on both lung fields and were treated by IV Amphotericin B and oral itraconazole. After completion of treatment, the lesion completely disappeared and he has been followed up for more than one year in his good condition. The second case showed a single nodule on his right lower lung field and were treated by both medication and surgery. The patient recovered well and had been doing well until 4th postoperative month when he developed humoral rejection and expired.

Primary choriocarcinoma of the lung is extremely rare and have been reported ten and several cases only in the literature. It is very difficult to confirm the "Pure primary pulmonary choriocarcinoma" clinically, so most cases that have been reported in the literature confirmed by autopsy and the prognosis is relatively poor compared with metastases. We experience one case of the primary pulmonary choriocarcinoma. She was 53 year old multiparous woman[4 \ulcorner0 \ulcorner2 \ulcorner0] who complain right chest pain for 4 years. On plain film and computerized tomogram of the thorax at admission, 2.5cmx3.5cmx5 cm sized, well demarcated ovoid mass was founded on the right middle lobe just below the parietal pleura and growing rapidly on plain film to 5cm x 6.5cm x 7cm after 15 days. We confirm the choriocarcinoma in the lung by percutaneous needle aspiration biopsy and strongly suspect primary after various examination for rule out metastases from the ovary or uterus. We perform middle lobe lobectomy because that can not confirm the primary or the metastases because there are not complete histological examination by bilateral ovariectomy and hysterectomy, and under the belief that extragestational or extragonadal primary choriocarcinoma is more resistant to the chemotherapy, and could be reduce the duration of hospitalization and the amount of chemotherapy used to achieve remission On 14th postoperative day, serum p-HCG level was returned to normal limit, and perform chemotherapy two times on 3rd and 5th week for prevention surgical traumatic hematogenous metastases or undetected microfocus, but the patient expire on 68th postoperative day due to intracerebral hemorrhage in the intracranial choriocarcinoma which strongly suspected surgical traumatic hematogenous metastases.etastases.

A 52-year-old man was referred to our clinic for an 11.3 mm nodule in the left lower lobe that was discovered on a chest computed tomography (CT) scan. Eleven small nodules were subsequently found in both lungs. Initially, we performed a transthoracic needle aspiration using CT scan guidance. The pathologic report showed a few clusters of atypical cells that were suspicious for malignancy. The positron emission tomography images revealed multiple lung nodules scattered throughout both lungs. The largest nodule (11.3 mm) in the left lower lobe did not have any discernible fludeoxyglucose uptake. For pathologic confirmation, we consulted a thoracic surgeon to perform the video-assisted thoracoscopic surgery. The final diagnosis was minute pulmonary meningothelial-like nodules (MPMNs). MPMNs are benign in nature, and only a few cases require treatment. However, when clinicians are suspicious of potential malignancy, a pathological correlation is essential, even if the final diagnosis is MPMNs.

Primary lung lymphoma is an uncommon tumor, which constitutes 0.5% of primary lung cancer, and 3% of extranodal lymphoma. The most frequent radiologic presentation of pulmonary parenchymal lymphoma is single mass or nodule. But we have experienced a case which was radiologically presented as patchy lung infiltration at first, and then progressive multiple reticulonodular infiltrations in lung. A 48-year-old woman was admitted to the hospital because of fever and cough. Chest PA obtained on admission revealed multiple patchy infiltration. Eventually, open lung biopsy was performed and the specimen disclosed extranodal NK/T cell lymphoma, and in bone marrow aspiration, hemophagocytosis was present. We report a case of primary extranodal NK/T cell lung lymphoma presented as patchy lung infiltrations, which was treated with chemotherapy.

Five dogs at the age of 2-13 years, with variant respiratory signs like as dry cough, dyspnea, exercise intorelance and lameness were presented. On thoracic radiographs, all dogs had abnormalities such as soft tissue density, round mass image, increased pulmonary infiltration and pleural effusion. All dogs were diagnosed as adenocarcinoma on cytopathologic examinations by fine needle aspiration with ultrasound guidance. Computed tomography was performed in three cases to evaluate clinical stage. Primary papillary adenocarcinoma was confirmed after necropsy in one case.

Follicular bronchitis/bronchiolitis is pathologically characterized by peribronchiolar lymphoid follicles, which is one of reactive pulmonary lymphoid disorders. It is associated with 1) the result of infections such as mycoplasma, chlamydia etc., 2) immunodeficiency syndromes, 3) connective tissue diseases such as rheumatoid arthritis and Sjogren's syndrome and 4) local or systemic hypersensitivity reaction. And it can be also developed without obvious causes and associated diseases(idiopathic). Radiologically it represents as bilateral interstitial patterns of pulmonary infiltrates. In this case, a 49 year-old woman was presented with intermittent cough and sputum. On chest X-ray and CT, $5\times4$ cm sized mass in right upper lobe and paratracheal lymphadenopathies were detected, by which lung malignancy was suspected. Bronchoscopy, trans bronchial lung biopsy and transthoracic needle aspiration showed non-specific findings only. After right upper lobectomy, we could confirm a case of follicular bronchiolitis which presented as an unusual mass-like radiologic finding.

This study was aimed to identify surgical ward nurses' importance-performance awareness toward early mobilization after abdominal surgery patients. The date were collected from 162 nurses and the importance and performance of early mobilization were analyzed by the IPA method. The collected data were analyzed using the SPSS/WIN 25.0 by implementing descriptive statistics, independent t-test, paired t-test, and ANOVA. Early mobilization was divided into exercise of pulmonary complications and early ambulation. As a result of the study, the areas requiring concentration were 'check risk of aspiration', and areas requiring improvement were 'oral care', 'check lung sound', 'percussion/vibration', 'suction', and 'reinforcement exercise in bed'. Therefore, each item of early mobilization is recommended to reduce the gap between importance and performance in clinical care.

Purpose: Since its implementation, flexible fiberoptic bronchoscopy (FBS) has played an important role in the diagnosis and treatment of tracheobronchial tree and pulmonary disease. Although FBS is often performed by endoscopists, it has also been performed by surgeons, albeit rarely. This study investigated FBS from the surgeon's perspective. Methods: This retrospective study included patients who underwent FBS performed by a single thoracic surgeon between March 2017 and December 2021. Accordingly, the epidemiology, purpose, results, and complications of FBS were analyzed. Results: A total of 47 patients received FBS, whereas 13 patients underwent repeat FBS. Their mean age was 60.7 years. The main organs injured involved the chest (n=22), brain (n=9), abdominal organ (n=7), cervical spine (n=4), extremities (n=4), and face (n=1). The average Injury Severity Score was 22.5. Indications for FBS included atelectasis or haziness on chest x-ray (n=34), pneumonia (n=17), difficult ventilator management (n=7), percutaneous dilatory tracheostomy (n=3), blood aspiration (n=2), foreign body removal (n=2), and intubation due to a difficult airway (n=1). The findings of FBS were mucous plugs (n=36), blood and blood clots (n=16), percutaneous dilatory tracheostomy (n=3), foreign bodies (n=2), granulation tissue at the tracheostomy site (n=2), tracheostomy tube malposition (n=1), bronchus spasm (n=1), difficult airway intubation (n=1), and negative findings (n=5). None of the patients developed complications. Conclusions: FBS is an important modality in the trauma field that allows for the possibility of diagnosis and therapy. With sufficient practice, surgeons may safely perform FBS at the bedside with relative ease.
