Lymphangioleiomyomatosis (LAM) is a rare, cystic lung disease that is associated with mutation in the tuberous sclerosis genes, renal angiomyolipomas, lymphatic spread and a remarkable female gender predilection. The pathology of LAM is represented by the proliferation of immature smooth muscle cells in the walls of airways, and venules and lymphatic vessels in the lung. The clinical course of LAM is characterized by progressive dyspnea on exertion, recurrent pneumothorax and collections of chylous fluid. The diagnosis of pulmonary LAM can be made on chest X-ray, a high-resolution CT scan and lung biopsy. We experienced a case of pulmonary lymphangioleiomyomatosis in a 28-years-old female patient who had suffered from progressive dyspnea on exertion, so we report on it along with a brief review of the relevant literature.

Glandular papilloma of the lung is one of three histologic types of solitary endobronchial papillomas. It is known as an uncommon benign neoplasm. No malignant glandular papillomas have been reported. Herein, the first case of granular papilloma with malignant transformation is reported. A 74-year-old man with huge right lung mass extended upper and lower lobe was admitted to the hospital complaining of progressive cough and dyspnea. An open lung biopsy was performed. Microscopically, the tumor showed papillary growth pattern with thick fibrovascular cores. The stroma of the fibrovascular cores shown the infiltration of lymphoplasmacytic cells and proliferation of capillaries. The epithelial cells surrounding the papillary fronds were cilliated columnar cells with focal cellar atypia, and frequent mitoses. Suspicious pleural invasion foci were identified. The Ki-67 labeling index was about 24.3% and p53 labeling index was about 31.7%. Glandular papilloma is known as a benign neoplasm, which is lack of atypia and mitosis. In present case, there were several indications of malignant transformation, such as cellular atypia, frequent mitosis, architectural distortion, and pleural invasion. Pathologists must be aware that glandular papilloma can have a changes of malignant transformation. Further studies about disease behavior and molecular characteristics are needed.

Eighty-four patients with pulmonary metastases from gestational choriocarcinoma were treated at the Catholic Medical Center between August, 1985 and August, 1991. Among these 13 patients underwent thoracotomy with resection of pulmonary lesions and the results obtained were follows. 1] The ages of the patients ranged from 26 to 47 years, with a mean age of 31 years. 2] The frequency of chemotherapy before operation ranged from zero to 46, with a mean frequency of 13.6. 3] Four patients were operated upon for a solitary metastasis of the lung; 6 patients, for unilateral multiple metastases and 3 patients, for bilateral pulmonary metastases. 4] Eight patients underwent wedge resection; 1 patient, segmentectomy; 2 patients, lobectomy; 3 patients, open lung biopsy. The lung lesions of eleven patients showed hemorrhagic necrosis[among these, 2 patients combined with pulmonary tuberculosis]; one was non-necrotic choriocarcinoma; another one was metastatic lung carcinoma from endocrine cancer of unknown origin. 5] Among twelve patients who had managed with chemotherapy before thoracotomy three patients were in remission; among 13 patients who had undergone thoracotomy 6 patients were in remission. 6] The median survival time of these patients was 25.8 months with 3 postoperative deaths. Subsequently, in the patients with pulmonary metastases from choriocarcinoma, if the primary tumor is under control, there are no other metastases, and the patients should be able to tolerate the planned operation, it is necessary to undergo aggressive thoracotomy for diagnostic purposes; for therapeutic purposes only when the pulmonary lesion is the only remaining source of increased hCG excretion; for reduction of tumor volume to shorten hospitalization or to reduce the quantity of drugs.

The malignant fibrous histiocytoma was the most common soft tissue sarcoma in late life adult. It was first described in 1964 by 0' Brien and Stout. It's histiogenesis had been considered to be of histiocytic origin. It Involves the extremities, retroperitoneum and trunk. It usually metastasizes to the lung. but primary lung lesion is extremly rare and it's prognosis was poor. We have experienced a case of MFR, which was confirmed by open lung biopsy. So we report a case of MFR of the lung with review of literature.

Background: The main goal of this study was to evaluate the diagnostic efficacy of reverse transcription-nested polymerase chain reaction (RT-nested PCR) in bronchial washing fluid with MAGE A1-6 common primers for the detection of lung cancers invisible by bronchoscopy. Methods: To determine the expression of MAGE A1-6 gene in 189 lung cancers diagnosed by conventional fluoroscopy-guided lung biopsy and 89 cancer-free controls, RT-nested PCR was performed in bronchial washing specimens. We analyzed MAGE A1-6 RT-nested PCR data according to tumor histology, stage, size, and compared them with cytological data. Results: 189 patients (111 cases in adenocarcinoma, 47 cases in squamous cell carcinoma, 22 cases in small cell lung carcinoma, and 9 cases in other cancers) and 89 benign patients were investigated. The expression of MAGE was performed by nested RT-PCR using common MAGE primer. Among 189 cancer patients, the expression rate of MAGE was 49.2%, and the positive predictive value was 89.4%. However, the expression rate of MAGE in patients with benign lesions was 12.4%. In peripheral lung cancer, the positive rate of MAGE expression was 57.4% in squamous cell carcinoma, 44.1% in adenocarcinoma and 59.1% in small cell lung cancer. Whereas the expression rate of bronchial washing cytology in peripheral lung cancer was 9.0% (p=0.011). Conclusion: MAGE RT-PCR in bronchial washing fluid gave us promising data for the detection of peripheral lung cancer. It could be a useful method for selecting diagnostic tools for peripheral lesions.
