We report the case of a 68-year-old man with a stromal tumor of uncertain malignant potential (STUMP), which had metastasized to the lung. The patient complained of an enlarged mass in the anterior chest. Chest computed tomography (CT) showed a sternal abscess with multiple nodules in both lungs. A thoracoscopic lung biopsy of the nodules and incision/drainage of the sternal mass were performed simultaneously. CT of the pelvis revealed an enlarged prostate with irregular cystic lesions in the pelvis. Prostate biopsy was done and demonstrated hypercellular stroma with minimal cytological atypia, a distinct pattern of STUMP. The sternal abscess proved to be tuberculosis and the lung lesion was consistent with STUMP, which had spread from the prostate. However, to our knowledge, the tuberculous abscess might not be assoicated with STUMP in the lung. The patient refused surgical prostatectomy and was discharged with anti-tuberculosis medication. On one-year follow up, the patient had no evidence of disease progression.

The lung is one of the most frequent sites of metastasis for extrathoracic tumors. Certain malignancies show a particular tendency to metastasize to lung, and in 15 to 25% of these cases, lung involvement is the only manifestation of metastatic disease. The most common presentation is the form of multiple bilateral nodules or masses of varying sizes. Lymphangitic metastasis is comprising 6 to 8% of all pulmonary metastasis. A striking variant of parenchymal involvement occures when dyscohesive tumor cells fill alveoli to produce a tumoral pneumonia. Carcinomatous lymphangitis of prostate origin is infrequent and usually carries a poor prognosis, and tumoral pneumonia of it is extremely rare. We report herein a case of prostate carcinoma metastasizing to lung, simulates atypical pneumonia, and disclosed by acute chest illness.

Carcinoma of the prostate is a common malignancy affecting elderly men. Lung metastasis from prostate cancer occurs frequently, but tumor metastasis to the central bronchi that clinically mimics primary bronchogenic carcinoma are very rare. We report a 73-year old man with endobronchial metastasis from prostatic carcinoma presented with respiratory symptom cough. Diagnosis of tissues taken from materials which were used for bronchoscopic biopsy and prostate biopsy and immunohistochemical staining for prostate specific antigen (PSA) confirmed a case of endobronchial metastasis from prostatic carcinoma. Hormonal therapy (LHRH agonist) was applied to this patient.

Talus tuberculosis is a rare disease, even in an endemic tuberculosis area. In reviews of the worldwide literature, only 18 cases of talus tuberculosis have been reported. Recently, we experienced a case of a 70-year-old polycythemia vera patient with right metatarsopharyngeal joint pain for 2 months duration who was diagnosed with talus tuberculosis with prostate involvement. Tuberculosis should be considered as one of the causes of monoarticulitis, especially in countries, where the disease is endemic. Additionally, we highly recommend taking a biopsy of the site of suspected infection because an early diagnosis is the key to successful treatment.

The lung is the most common site for the metastasis of extrapulmonary malignant tumors. However, endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are the breast, renal and colorectal carcinomas. Lung metastasis from prostate cancer is often encountered but EBM is rare. We report a 74-year old man with endobronchial metastases from prostatic carcinoma presented with cough. The diagnosis of prostatic cancer and the endobronchial metastasis were confirmed by immunohistological staining with the prostate specific antigen. Hormonal therapy (lutenizing hormone releasing hormone agonist) was applied to this patient.

Androgen deprivation therapy, which is the standard treatment for metastatic prostate cancer, includes nonsteroidal antiandrogenic drugs, such as flutamide, nilutamide and bicalutamide. Of them, bicalutamide rarely induces interstitial pneumonia. We report a case of bicalutamide-induced interstitial pneumonia. A 68-year old male diagnosed with prostate cancer and multiple bone metastases presented with dry cough and low grade fever for 3 days. He had taken bicalutamide (50 mg/day) for 13 months. High resolution computed tomography revealed ground glass opacity in his right upper lung. The laboratory studies showed no eosinophilia in the serum and bronchoalveolar lavage fluid. Despite the use of antimicrobial agents for 2 weeks, the extent of the lung lesions increased to the left upper and right lower lung. He had no environmental exposure, collagen vascular disease and microbiological causes. Under the suspicion of bicalutamide-induced interstitial pneumonia, bicalutamide was stopped and prednisolone (1 mg/kg/ day) was initiated. The symptoms and radiologic abnormalities were resolved with residual minimal fibrosis.

A hidden primary tumor presenting as an isolated lung mass is a diagnostic challenge to physicians because the diagnosis of lung cancer is likely to be made if the histologic findings are not inconsistent with lung cancer. A large lung mass was found incidentally in a 59-year-old man. Although adenocarcinoma was diagnosed by percutaneous needle biopsy, thyroid transcription factor-1 (TTF-1) immunostaining was negative, raising suspicion that there was another primary site. There was no abnormal finding except for the lung mass on a $^{18}FDG$-PET/CT scan and the patient did not complain of any discomfort. Finally, prostatic cancer was confirmed through the study of tumor markers and prostate-specific antigen (PSA) immunostaining. Because of the rare presentation of a single lung mass in malignancies that have another primary site, physicians should carefully review all data before making a final diagnosis of lung cancer.

We have experienced 131 cases of chest wall tumor, from April 1974 to April 1984 at the Kyung Hee University hospital. We analyzed 131 cases of chest wall tumors, 59 cases were primary chest wall tumors and 72 cases were secondary chest wall tumors. The results were following; 1.Of primary benign chest wall tumors [56], lipomas were most common and located mainly in the scapular area [37/56]. 2.Of secondary malignant chest wall tumors [72], which originated from hung tumors were most common [27/72], & breast [8/72], liver [8/72], prostate [6/72] & stomach [3/72] were followed lowed in orders. 3.We excluded out the Rib tuberculosis.

Background: Elevated expression of cyclooxygenase-2 (COX-2) and Polo-like kinase-1 (PLK-1) is observed in a wide variety of cancers. Augmented expression of COX-2 and enhanced production of prostaglandin $E_2(PGE_2)$ are associated with increased tumor cell survival and malignancy; COX-2 has been implicated in the control of human non-small cell lung carcinoma (NSCLC) cell growth. PLK-1 siRNA induced the cell death of lung cancer cells and the systemic administration of PLK-1 siRNA/atelocollagen complex inhibited the growth of lung cancer in a liver metastatic murine model. COX-2 and PLK-1 are involved in proliferation and in cell cycle regulation, and there is a significant correlation between their interaction in prostate carcinoma. Methods: In this study, we investigated the pattern of COX-2 and PLK-1 expression in NSCLC, after treatment with IL-1$\beta$, COX-2 inhibitor and PLK-1 siRNA. Results: Expression of PLK-1 was decreased in A549 COX-2 sense cells, and was increased in A549 COX-2 anti-sense cells. Knock out of PLK-1 expression by PLK-1 siRNA augmented COX-2 expression in A549 and NCl-H157 cells. When A549 and NCI-H157 cells were treated with COX-2 inhibitor on a dose-dependent basis, PLK-1 and COX-2 were reduced. However, when the expression of COX-2 was induced by IL-1$\beta$, the production of PLK-1 decreased. Conclusion: These results demonstrate that COX-2 and PLK-1 are regulated and inhibited by each other in NSCLC, and suggest that these proteins have a reverse relationship in NSCLC.

Trousseau's syndrome comsists of migratory thrombophlebitis and thromboembolic disorders of the venous and arterial systems in a malignancy or occult cancer. The overall incidence has been reported to vary from 1 to 11%. Pancreatic, lung, prostate, and stomach cancer is associated with the greatest risk of thromboembolic events. We encountered a 49-year-old man who presented with painful swelling of his lower legs. The chest radiograph showed increased opacity of the Left middle lung fields and Doppler sonography showed a thrombus in the left superficial femoral vein. Chest Computed Tomography showed a 5cm sized left hilar mass invading the pericardium with lymphadenopathy. The bronchoscope biopsy demonstrated an adenocarcinoma of the lung. Platinum based chemotherapy and anticoagulant therapy with warfarin was carried out. The patient was later discharged with an improvement in the painful swelling of his lower legs.
