This report is an analysis of the medical records of 83 patients registered between 1960 and 1980 at Helsinki University Central Hospital as having malignant pleural mesothelioma. 65 of 83 patients had histologically confirmed malignant mesothelioma, and are the focus of this analysis. The remaining 18 (22%) patients were excluded because malignant mesothelioma was only confirmed cytologically, or because the primary tumor was not a mesothelioma. The ratio of men to women was 2:1.30 of 65 (46%) patients were not known or not likely to have been exposed to asbestos. The main symptoms at presentation were dyspnea, cough, chest pain, fatigue and weight loss. The median survival from diagnosis was 12 months, and from the onset of symptoms 18 months. Clinical stage and performance status were significant prognostic factors. Hematogenous metastases were present at autopsy in most cases. Disease and performance status therefore need to be well established and documented in clinical trials involving mesothelioma.

A 63-year-old female, with a chief complaint of right chest pain was referred to our hospital because of an abnormal right chest wall shadow on chest X-ray. A rib tumor was suspected based on her chest CT scan. Percutaneous needle biopsy yielded a diagnosis of well-differentiated adenocarcinoma. As metastatic rib tumor was suspected, the primary tumor was sought for. A thyroid gland nodule was recognized by ultrasonography, and the cytological diagnosis was class V. Immunohistological demonstration of the thyroglobulin studies of the rib tumor tissue revealed papillary and trabecular patterns of cell arrangement and the presence of thyroglobulin existence. Definitive diagnosis of metastatic rib tumor from thyroid cancer was established. Immunohistological examination is useful to confirm the diagnosis of metastatic cancer of thyroid origin.

A 61-year-old female was admitted to our hospital because of a mass in right lateral chest wall and chest pain. Chest X-P and CT scans showed a right chest wall tumor and pleural effusion. Biopsy specimen from the chest wall tumor revealed an adenocarcinoma, not a mesothelioma, based on immunohistochemical study. Cancer cells were also detected in pleural effusion. Imaging diagnostic analysis could detect no primary tumor in lung field or other organs. High levels of CA125 were noticed: 9,610 U/ml in serum and 37,600 U/ml in pleural effusion, respectively. Finally, there was a possibility that the chest wall tumor might be a metastatic lesion from undetected ovarian cancers, so three cycles of combined chemotherapy (CDDP+ADM+CPA) were done. CDDP plus OK-432 was also injected two times intrapleurally. After chemotherapy, the chest wall tumor and effusion disappeared and the serum CA125 level decreased to the normal range.

In October 1988, a 19-year-old man was admitted with complaint of chest pain. Chest X-ray film and CT scan of the chest revealed a large mediastinal mass and several bilateral pulmonary nodules. Serum hCG and alpha-fetoprotein levels were 5096.0 mIU/ml (normal < 2.0) and 2176.9 ng/ml (normal < 10), respectively. Percutaneous needle biopsy of the mediastinal tumor disclosed an immature teratoma. The patient had normal testes on physical examination. CT scans of the brain and abdomen, and radioisotope scanning of the bones showed no abnormality. He was diagnosed as having a primary mediastinal nonseminomatous germ cell tumor (mixed cellular type) with pulmonary metastasis. On October 31, induction chemotherapy was started with PVB regimen: cisplatin 20 mg/m2 administered intravenously (i.v.) on days 1 through 5 every three week (three courses), vinblastine 0.15 mg/kg i.v. on days 1 and 2 every three weeks (three courses), and bleomycin 30 mg administered by i.v. push (starting on day 7) weekly x 9. Following the chemotherapy, serum alpha-fetoprotein fell to the normal range. Serum hCG decreased rapidly but did not reach the normal range. On January 7, 1989, en bloc resection of the residual primary tumor was performed which involved partial pericardiectomy and wedge resection of the left upper lobe. Four residual pulmonary nodules were also removed. Histologically, the surgical specimen was composed of fibrous, necrotic tissue mainly and immature teratoma partially.(ABSTRACT TRUNCATED AT 250 WORDS)

We report an adenocarcinoma of the thymus in a 39-year-old male. The patient presented with chest pain, and the chest X-ray film and chest CT showed an abnormal mass in the mediastinum. A preoperative clinical diagnosis of invasive thymoma was suspected. The tumor was resected along with the pleura and pericardium. The pathological findings were compatible with those of adenocarcinoma of the thymus. Despite a thorough examination, no primary tumor could be found. An adenocarcinoma of the thymus is rare and to the authors knowledge there are few previous reports in the literature.

This report describes an extremely rare combination of mediastinal germ cell tumor and visceral hemangiomatosis in a 17-year-old boy who initially presented with chest pain and dyspnea. He was treated with chemotherapy consisting of cisplatin, cyclophosphamide, bleomycin, vinblastine, and dactinomycin followed by surgery. Multiple low-density nodules developed in the spleen three weeks later, suggesting metastases from the primary tumor, but the resected specimen showed cavernous hemangiomas within the splenic parenchyma. The patient died of recurrence of germ cell tumor 19 months after the initial treatment. Postmortem examination disclosed multiple hemangiomas in the lung and liver similar to those in the spleen.

Angiosarcomas are rare malignant vascular tumors with a high rate of metastasis involving lungs (most commonly), liver, regional lymph nodes, bone, and other sites. In this study, we have reviewed the clinical presentation and histopathology of 21 cases of extracutaneous angiosarcoma metastatic to the lungs. Tumors with exclusively pleural involvement were excluded. Patients presented with dyspnea, chest pain, and/or hemoptysis lasting a few weeks to months. Radiologically, the most common finding comprised multiple peripheral lung nodules (57%), often accompanied by infiltrates. For 11 cases (52%), the primary tumor was not identified at the time of presentation. Vasoformative areas were identified in 15 cases (71%). Nine cases comprised spindle cells (43%), two contained epithelioid cells (9.5%), and 10 consisted of both spindle and epithelioid cells (48%). Nuclear pleomorphism was at least moderate in all cases. However, five tumors contained regions of minimal nuclear atypia. Hemorrhage, siderophages, and fibrosis were commonly present. Immunohistochemical staining (IHS) was performed on 14 cases. Thirteen tumors showed reactivity for vascular markers. Tumor cells reacted for Von Willebrand factor in 13 of 14 cases, and CD31 and CD34 were each positive in 2/2 cases. Two cases (of nine examined) also expressed cytokeratins. Because the tumor often first presented in the lungs before the primary sarcoma was identified, the clinical impression included both benign and malignant entities. For patients with primary cardiac tumors, symptoms referable to the primary tumor complicated the clinical presentation, and radiologic evaluation supported a clinical diagnostic impression of non-neoplastic pericarditis. Thus, angiosarcoma in the lung may elude diagnosis until histopathologic evaluation of the lung biopsy.

Primary pulmonary artery sarcoma is an uncommon tumor. Mandelstamm in 1923 was the first to describe the disease in an autopsy. Since then, less than 200 cases were reported. The incidence is 0.001-0.03%, they are always highly malignant sarcoma, and women are involved twice as often as men. The presentation is often cough, dyspnea, and chest pain, and patients are usually diagnosed as suffering from pulmonary emboli, and primary tumor of the pulmonary artery is not usually considered in the differential diagnosis. The diagnosis of pulmonary artery sarcoma is made of the "clot" resected during pulmonary artery thrombendarterectomy. Our suggestion is that in patients with unilateral pulmonary artery occlusive disease, no evidence of positive hypercoagulability tests, and no history of thromboembolism, a high suspicion of pulmonary artery sarcoma should be kept in mind, and an angiographic-guided biopsy from the intra-arterial occlusive material should be considered. The treatment is surgery. The survival without operation is less than 2 months. Some patients were treated with adjuvant chemotherapy. We report on a woman with undifferentiated sarcoma of the pulmonary artery, mimicking chronic pulmonary artery emboli. This case illustrates the need to consider malignancy in the differential diagnosis of patients having pulmonary emboli.

We performed retrospectively study on 136 thoracoscopies done in our clinic in the period January 2000 and December 2004. We reviewed 136 thoracoscopies, 71 patients were male and 65 were female (mean age 58.4 years). Straw colored effusions were present in 78 cases (57%) and hemorrhagic in 58 cases (43%). The surgical procedure consist in diagnostic of thoracoscopy with drainage of pleural effusion, multiply pleural biopsy, pleurodesis and continuous pleural drainage. In our study, the talc powder (5g) was successfully as sclerosing agent. The primary tumor was: lung-63 (46%), breast-26 (19%), mesothelioma-21 (15.5%), stomach-3, ovarian-3, prostate-3, colon-2, lymphoma-1, leukemia-2, plasmocytoma-1 and unknown primary tumor in 11 cases (8%). Adverse effects included-chest pain-35 cases (25%), fever-20 cases (15%), empyema-6 cases (4.5%), prolonged air leak-5 cases (4%), pulmonary infection-2 cases, acute respiratory failure-1 case, malignant invasion of scar-1 patient. For statistical analysis, the success of talc pleurodesis was defined as the absence of pleural fluid on the follow-up chest radiographs. Pleurodesis was successful in 125 cases (92%) of the patients after 1 month-follow-up. Thoracoscopic talc pleurodesis is a safe, economical and effective treatment for malignant pleural effusion.

Pleuropulmonary synovial sarcoma (PPSS) is increasingly recognized as a subtype of sarcoma because of the recent identification of a distinctive chromosomal translocation specific to synovial sarcoma. Soft-tissue synovial sarcoma is far more common than PPSS and typically develops in para-articular locations of the extremities; affects young and middle-aged adults, with no difference in distribution between the sexes; and has well-documented radiologic manifestations. PPSS may arise in the chest wall, heart, mediastinum, pleura, or lung, and it shares patient demographics and several imaging features with its soft-tissue counterpart. Patients present with a cough, chest pain, or dyspnea. On chest radiographs, PPSS typically appears as a sharply marginated mass with uniform opacity, based either in the pleura or in the lung, and often accompanied by an ipsilateral pleural effusion. Computed tomographic images show a well-circumscribed heterogeneously enhanced lesion without associated involvement of bone and without calcifications (except in the case of a chest wall primary tumor). Magnetic resonance imaging provides superior demonstration of nodular soft tissue and multilocular fluid-filled internal components of PPSS, in addition to peripheral rim enhancement after the intravenous administration of a gadolinium-based contrast material such as gadopentetate dimeglumine. Current treatment consists of surgical resection followed by chemotherapy, radiation therapy, or both.
