Pulmonary alveolar proteinosis is a rare disorder in which lipoproteinaceous material accumulates within the alveoli. We report a case of pulmonary alveolar proteinosis in a 41 year old female patient. She complained of a dry cough in the preceding 6 months. She presented symptoms of mild hypoxemia and diffuse infiltration at both lower lung fields. A milky fluid was obtained by bronchoalveolar lavage. We confirmed by light microscopic examinations of the lung tissues obtained by transbronchial lung biopsy. Through several follow-ups, the patients symptoms were mild.

The large cell neuroendocrine carcinoma is uncommon and its diagnostic criteria was recently established as pulmonary neuroendocrine carcinoma. A 74-year-old man who was a heavy smoker without symptoms was presented with a lung mass in right lower lobe. He was diagnosed as having large cell neuroendocrine carcinoma by needle biopsy. He was treated with right lower lobe lobectomy and mediastinal lymph node dissection. We experienced one case of large cell neuroendocrine carcinoma of lung and report it with reference.

Primary malignant lymphomas of the lung are rare and known often to be localized, solitary pulmonary lesions, in chest radiograph. Because they are highly treatable contrast to the other primary lung cancer, the distinction is important. A 35-year old man who was admitted for a solitary pulmonary nodule in the right middle lobe. Percutaneous needle aspiration disclosed diffuse, small cell lymphoma. Bone marrow biopsy showed no evidence of neoplastic lymphoid cell infiltration. There were a walnut sized mass involving right middle lobe with a small satellite nodule at 2cm distal to the right upper lobe bronchial orifice. The histopathology of the bilobectomized specimen showed diffuse, small cell, malignant, non-Hodgkin`s lymphoma. Immunologic subtype was defined as B-cell type.

The diffuse nodular lung lesion has a diagnostic problem and should be made differential diagnosis. A chest X-ray of 62-year-old male patient with dyspnea showed small-sized scattered multinodular lesion on entire lung field. Bronchoalveolar lavage and transbronchial needle aspiration showed the non-specific findings, so open lung biopsy was done and revealed bronchioloalveolar cell carcinoma.

Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is rare, with a more favorable prognosis compared with that of other types of non-small cell lung cancers. Herein, we describe an interesting case of primary pulmonary LELC confirmed postoperatively, which had been initially diagnosed as poorly differentiated adenocarcinoma. We suggest that despite the rarity of pulmonary LELC, it should be included as one of the differential diagnoses for lung malignancies. Physicians should consider taking a larger biopsy, especially when histologic examination shows undifferentiated nature.

Diagnostic procedures in pregnant wowen is limited and is usually delayed, especially so if she is on mechanical ventilation. A 28-year-old pregnant woman with severe dyspnea was referred to our hospital under the impression of miliary tuberculosis. The respiratory failure was so severe that patient had to be managed with mechanical ventilator under clinical impression of overwhelming pneumonia or pulmonary tuberculosis. But the patient's conditions deteriorated. Bronchoscopy and blind transbronchial lung biopsy performed to determine the nature of the etiology, and to our surprise, revealed squamous cell carcinoma of the lung.

Primitive neuroectodermal tumor (PNET) arising primarily in the lung is an extremely rare and aggressive malignancy with poor chances of patient survival. We present a case of long-term survival by a 29-year-old woman with PNET diagnosed after a hertological and immunohertochemical examination of a biopsy specimen obtained by performing video-assisted thoracic surgery. The patient underwent a left lower lung lobe lobectomy and 6 cycles of adjuvant chemotherapy. The patient has been free of any symptoms of the recurrence of the disease for 6 years after treatment completion.

Spontaneous pneumothorax accompanying primary lung cancer is rare and its occurrence as an initial sign of primary lung cancer is much rarer. A few articles on spontaneous pneumothorax accompanying lung cancer have been published in Korea so far. Lung cancers, diagnosed after spontaneous pneumothorax, are usually in advanced stage, so that conservative treatment modalities such as closed tube thoracostomy, chemotherapy, or radiotherapy are the mainstream of the treatment. We experienced a case of local recurrence of primary lung cancer in six months after radical resection and radiotherapy of neoplasm performed immediately after the diagnosis by excisional biopsy of bulla, for which resection and pleurodesis had been done under the impression of spontaneous pneumothorax. In this paper, we report the case and follow-up observation of the patient.

Background : Forceps biopsy, bronchial brushing, and bronchial washing are used in conjunction with bronchoscopy to provide specimens for histologic and cytologic analysis in patients with suspected lung cancer. This study was performed to evaluate how many times brushing should be done and how much fluid should be used during bronchial washing for increasing diagnostic yield, and to evaluate which combination of these procedures gives the highest diagnostic yield. Methods : Forty patients, with suspected lung cancer, who had bronchoscopically visible lesions were enrolled in this prospective study. During one bronchoscopic examination four forceps biopsies, four bronchial brushings, and bronchial washing were done in all patients. The patients were divided into four groups by the amount of normal saline used for bronchial washing; group I, 10 ml ; group II, 20ml ; group III 30ml, and group IV, 40ml. We analyzed the results in 36 patients confirmed as lung cancer. Results : The diagnostic sensitivity of bronchial washing before and after forceps biopsy and bronchial brushing were 36% and 28%, respectively. The cumulative diagnostic sensitivity of bronchial washing was 47% and significantly higher than that of bronchial washing before or after forceps biopsy and bronchial brushing (p<0.05). The diagnostic sensitivity of bronchial washing with saline of 30ml was significantly higher than that of bronchial washing with saline of 10ml or 20ml (p<0.05). The diagnostic sensitivity of the first brushing was 75%, the second brushing 78%, the third brushing 83%, and the fourth brushing 67%. With repeated brushing up to three times, the diagnostic sensitivity increased to 92% (p<0.05). However, inclusion of the fourth brushing did not give a further increase of the diagnostic sensitivity. The diagnostic sensitivity of forceps biopsy was 86%. The diagnostic sensitivities of forceps biopsy by the type of bronchial lesion were as follows: tumor, 88%; infiltration, 67%; infiltration with nodularity, 80%; and collapse, 100%. The combination of forceps biopsy and bronchial washing gave a diagnostic sensitivity of 89%. The diagnostic sensitivity of combining forceps biopsy with bronchial brushing was 97%. Addition of bronchial washing did not increase the diagnostic yield over forceps biopsy and bronchial brushing. Conclusion : In patients with central lung cancer, forceps biopsies and repeated brushings up to three times should be done for maximal diagnostic yield.

A 29-year-old female patient presented with exertional dyspnea that she had suffered with for 2 months. The chest X-ray displayed right pleural effusion that was diagnosed as chyle, according to the level of cholesterol and triglyceride in the pleural fluid. VATS (video assisted thoracic surgery) of the right lung was performed on the 7th day of hospitalization for obtaining a lung biopsy and to control the of pneumochylothorax. On the 11th hospitalization day, VATS of left lung was also performed to control the recurrent pneumothorax via pleurodesis. The lung biopsy showed moderate amounts of spindle-shaped and rounded cells (so-called LAM cells), which were reactive to actin and HMB45 (on immunohistochemical stains). We report here on a rare case of lymphangioleiomyomatosis combined with chylothorax and bilateral pneumothroraces.
