Benign metastasizing leiomyoma (BML) is a rare entity, characterized by the occurrence of multiple smooth muscle nodules in the lung with histologically benign leiomyoma, Both the uterine and pulmonary tumors have been found to express estrogen and progesterone receptors, which suggest that the pulmonary lesions represented metastases from leiomyoma. We experienced a 41-year-old female patient with BML and report here with the literature review.

Benign metastasizing leiomyoma is a rare disease that histologically shows features of a benign tumor; however it can metastasize to the lung or other organs. We report here on a case of a 53-year-old Woman with benign metastasizing leiomyoma, and she was admitted to the hospital with symptoms of coughing for 2 months; she showed multiple diffuse nodular opacities of both lungs on a chest radiograph. She had undergone hysterectomy for leiomyoma of the uterus 13 years previously. Thoracoscopic lung biopsy was performed to rule out metastatic lung cancer. The pulmonary nodules appeared benign with a very low mitotic rate and they consisted of smooth muscle cells. The pathologic findings of the pulmonary nodules were consistent with benign metastasizing leiomyoma. The patient has been followed up closely without any specific therapy.

An unusual case of primary leiomyosarcoma at the left lower posterior chest wall with metastasis to the right lung parenchyme is presented. The patient was a 43-year-old man who was asymptomatic but a slow growing hard mass was noted at the left lower posterior chest wall. The chest computed tomography showed a tumor at the left lower posterior chest wall with multiple metastasis to the right lung. The left lower posterior chest wall mass was examined by percutaneous needle aspiration and it was revealed as rhabdomyosarcoma histologically. En bloc resection to the left lower posterior chest wall tumor and metastasectomy to the multiple nodules in the right lung were done and pathological examination finally revealed primary leiomyosarcoma at the left lower posterior chest wall with multiple metastasis to the right lung. Chemotherapy was scheduled as adjunctive measure.

We report here a case of pulmonary benign metastasizing leiomyoma from the uterus in a 45 year old woman. The patient presented for investigation of multiple pulmonary nodules on a routine chest roentgenogram. The patient had undergone uterine myomectomy due to uterine leiomyoma 10 years earlier. We performed thoracoscopic wedge resection for definitive diagnosis. Histologically, spindle shaped smooth muscle cells appeared between collagen stroma, histology similar to that seen in uterine myoma. The tumor tissue tested positive for estrogen and progesterone receptors. The pathological findings were consistent with benign metastasizing leiomyoma. The patient was in pre-menopause. She received no specific treatment for lung tumors, and we did not found any changes in the lesions after one year follow up without any medication.

Oriental medicine as a candidate for effective cancer treatment recently gain positive concerns in fields of therapeutic oncology. that is why some herbal medicines have been empirically safer in toxicity than anticancer drugs used in western medicine, and to show excellent therapeutic efficacy in human trial. Thus, these effects by clinically applied-herbs have not yet fully demonstrated in experimental tumor model. This study was initiated to evaluate the antitumor effect of Insambaekhaptang as candidate of antitumor-herbal agent against B16 melanoma metastasized into C57BL/6 mice lung. In experiment to test whether Insambaekhaptang can directly kill cancer cells in vitro or not, Insambaekhaptang showed direct killing action in concentration or higher against B16 melanoma cells using MTT assay, and showed lower IC50. Another experiment to know whether Insambaekhaptang can inhibit growth and metastasis of cancer cell or not, Insambaekhaptang significantly inhibited Solid tumor by intraperiperal injected-melanoma and lung metastasis induced by intravenous injected-melanoma in inbred C57BL/6 mice. When quantitative survival time increasing, we could obtain results that increased 113% in treated by Insambaekhaptang. These results show that Insambaekhaptang can inhibit growth of B16 melanoma cells through various biological mechanisms.

Giant cell tumor is usually found around the knee joint, especially in the distal femur or proximal tibia. Despite being classified as benign, it has unusual biological behavior of local aggressiveness and tend to have severely destructive lesion and develop rare pulmonary metastasis. Therefore, when the patient is presented to the physician with an expansile lytic lesion of challenging clinicopathologic entity extending to subchondral bone, the physician faces up to difficulties in treatment. We report a case of 25 years old patient having recurrent giant cell tumor in the right distal femur which developed metastasis to lung. The primary bone lesion was treated with local curettage and fillings with methylmethacrylate, but when he returned to the hospital two years later, the recurrence had developed with lung metastasis.

At OPD follow-up in December 1998, chest x-ray of a 42-year-old female showed a solit ary pulmonary nodule at a superior basal segment in the right lower lobe. After percut aneous transthoracic needle aspiration failure, wedge resection of the superior basal segment of lower lobe in right lung was performed for diagnosis and therapy. Three years ago, she had received surgery to remove a mass in the left buttock. The mass was pathologically diagnosed as malignant fibrous histiocytoma. She subsequently received 4500 rad radiotherapy for 35 days. Pathology confirmed metastatic malignant fibrous histiocytoma of the lung.

Background : The lung is the most common site for a metastasis of extrapulmonary malignant tumors. however, reports on an endobronchial metastasis are rare. An endobronchial metastasis is defined as a documented extrapulmonary neoplasms metastatic to the segmental or more proximal central bronchus within a bronchoscopically visible range. The purpose of this study was to define the clinical characteristics of an endobronchial metastasis of extrapulmonary malignancies. Materials and Methods : The clinical features and treatment outcomes of 27 endobronchial metastatic cancer cases were reviewed from June, 1991 to May, 2001 in the Severance Hospital. Results : The patients' age ranged from 18 to 75. There were 17 men and 10 women. The primary tumors included the colorectum in 7, the uterine cervix in 4, the stomach and the breast in 3 patients each, and an osteosarcoma in 2 patients. The main complaint of most patients was coughing and a chest X-ray revealed a hilar mass, a parenchymal, and an atelectasis. The mean recurrence interval time was 45.5 months. The median and mean survival times were 10 and 12.3 months, respectively. Conclusion : An endobronchial metastasis is an ominous finding, and is associated with advanced-stage diseases. It requires differential diagnosis with a primary bronchogenic carcinoma. If atypical clinical features are present or an atypical cell type is discovered by a biopsy of the lesion in the lung mass, the appropriate diagnostic studies should be undertaken.

Cryptococcosis is a subacute or chronic inflammation that's caused by infection from cryptococcus neoformans in the soil or dust that's contaminated by pigeon droppings. Pulmonary cryptococcosis occurs in immunocompromised patients, and particularly in HIV positive patients, but it rarely occurs in immunocompetent individuals. It is most often detected as asymptomatic single or multiple nodules that are found by chest X-ray examination. In these situations, the diagnosis for most cases is made by the histology of the resected lesion. We report here on a case of solitary nodular pulmonary cryptococcosis that occurred in a 32 years old female patient who underwent thyroidectomy for treating her thyroid cancer.
