1/142. Intramuscular solitary fibrous tumor: a clinicopathological case study.

    We present a case of extrapleural solitary fibrous tumor arising within the muscle, an unusual and hitherto-undescribed tumor lesion. A 42-year-old woman presented a painless mass in her left thigh. The lesion was depicted as an intramuscular mass that enhanced on both CT and MRI, showing quite rich tumor vascularity. The histological features of the tumor were spindle cell proliferation with various histological patterns, typical fibrocollagenous background, and positive immunoreactivity for CD-34.

2/142. Pseudomesotheliomatous carcinoma involving pleura and peritoneum: A clinicopathologic and immunohistochemical study of three cases.

    Pseudomesotheliomatous carcinoma is a rare variant of peripheral adenocarcinoma of the lung that can manifest clinical, radiologic, and pathologic features similar to malignant mesothelioma. We present three patients with pseudomesotheliomatous carcinoma of the lung. In one patient the carcinoma extended beyond the thorax and extensively involved the peritoneum, mesentery, omentum, and intestines. All patients experienced weight loss and chest pain. All were white men aged 63, 65, and 67 years. Two were smokers and had shortness of breath, cough, and pleural effusion. One had a history of asbestos exposure. No patient developed dyspnea or hemoptysis. One was successfully treated for prostatic carcinoma 18 months earlier. Radiographically, all tumors were pleura-based. Grossly, the tumors spread extensively over pleural (and in one case peritoneal) surfaces and mimicked malignant mesothelioma. Histologically, all tumors were poorly differentiated and necrotic; two tumors exhibited spindle-cell components and desmoplasia. Mucin production was detectable in none, 10%, and 50% of tumor cells. The percentages of tumor cells immunoreactive for Ber-EP4 were 70%, 100%, and 80%; for Leu MI 0%, 90%, and 50%; for epithelial membrane antigen 80%, 80%, and 100%; for B 72.3%, 0%, 90%, and 20%; for polyclonal carcinoembryonic antigen 0%, 10%, and 10%; and for monoclonal 5%, 0%, and 0%. Of these, Ber-EP4 and B 72.3 rendered the most reliable diagnostic results. The clinical, radiologic, and gross and routine histologic findings were similar to those of a malignant mesothelioma; the final diagnosis could be made based mainly on immunocytochemical results. We have reviewed the English and German literature regarding 65 such tumors and present our experience with three additional cases. We emphasize the application of immunocytochemical studies on pleura-based poorly or undifferentiated malignant tumors of unknown origin.

3/142. Subcutaneous seeding after ultrasound-guided placement of intrapleural catheter. An unusual complication of the intracavitary palliative treatment of pleural mesothelioma.

    Intrapleural catheters are useful in the palliative treatment of malignant effusions. Complications are infrequent and of little importance. We report a case of subcutaneous implantation metastasis along the course of intrapleural catheter, which had been placed under sonographic guidance in a patient with pleural mesothelioma. After drainage of the effusion, cisplatin plus cytarabine was administered via the chest tube, achieving complete remission of the pleural effusion. Subcutaneous metastasis became evident 3 months later and was the only sign of disease progression for 2 months. The seeding of cancer cells was probably caused by a small leakage of fluid around the chest tube that occurred during the placement procedure as a result of the increased intrapleural pressure caused by the large quantity of fluid that had accumulated in the pleural space.

4/142. Malignant mesothelioma presenting as pulmonary metastasis ahead of growth of primary tumour.

    A 59-year-old woman was admitted to Houju Memorial Hospital, Ishikawa, japan, because of cough and fever on 30 March 1997. A diagnosis of pneumonia was made and she was given antibiotics. Her symptoms improved but failed to resolve completely on antibiotic therapy. On 9 September 1997, she revisited the hospital because of bodyweight loss and malaise. There was no history of exposure to asbestos. The chest roentgenogram revealed infiltrative shadows with vague and indistinct margins suggesting inflammatory processes, which were more extensive than those investigated on her last visit. One month later, a giant tumour was detected rapidly growing from the mediastinum and open biopsy was performed. The histological examination confirmed that the tumour was a malignant mesothelioma and the intrapulmonary nodules were its metastases. This is a rare case of pulmonary metastasis being present for several months before an appearance of primary mesothelioma.

6/142. Primary pericardial mesothelioma presenting as constrictive pericarditis.

    Primary pericardial mesothelioma is a rare tumour, often discovered late in a patient's clinical course or at autopsy. Antemortem diagnosis is usually made at the time of surgery. A patient who presented with what appeared to be viral pericarditis in October 1997 is reported. Recurrent symptoms prompted re-evaluation with echocardiography, chest computed tomography, magnetic resonance imaging, cardiac catheterization and a diagnosis of constrictive pericarditis. Associated hepatic dysfunction was found to be secondary to congestion. After operative pericardiotomy and histological examination, primary pericardial mesothelioma was diagnosed. The lesion was surgically debulked.

7/142. diagnosis of malignant mesothelioma by fine needle aspiration of a cervical lymph node. A case report.

    BACKGROUND: Clinically documented distant metastases are rare in mesothelioma and tend to occur late in the course of the disease, well after the diagnosis has been made. In this instance, diagnosis was not made until a metastatic deposit was identified microscopically in the enlarged lymph node. CASE: A 65-year-old male with no definite history of occupational asbestos exposure presented with chest pain, pleural effusion and supraclavicular lymphadenopathy. Cytologic examination of material obtained by fine needle aspiration from his cervical lymph node revealed malignant mesothelioma. This was confirmed on histology. CONCLUSION: This was a particularly rare presentation and, as far as we are aware, was the first case in which mesothelioma was diagnosed by fine needle aspiration of a cervical lymph node. It serves to remind the pathologist that when confronted with a lymph node involved by tumor, the possibility of mesothelioma should be included in the differential diagnosis. The case also demonstrates the usefulness of fine needle aspiration in the diagnosis of metastatic tumor.

8/142. Malignant peritoneal mesothelioma with mimicry of pseudomyxoma peritonei in a patient with a history of perforated sigmadiverticulitis.

    We describe a 57-year-old man who presented with diffuse abdominal pain, abdominal enlargement, vomitus, dyspnea and a weight loss of 30 kg within 6 months. These acute symptoms were preceded by an episode of ascites and an acute sigmadiverticulitis 7 months ago. ultrasonography and computed tomography were suggestive of pseudomyxoma peritonei. However, malignant mesothelioma peritonei was diagnosed by open surgery with biopsy for histological examination. Despite R-2-resection of the tumor and following open hyperthermic intraperitoneal chemotherapy with initial remarkable recovery the patient died 5 months after therapeutical intervention. Malignant peritoneal mesothelioma is an extremely rare tumor with great diagnostic and therapeutic difficulties. We report a case including diagnostical work up and the medical surgical therapy of this disease.

9/142. Primary pericardial mesothelioma presenting as constrictive pericarditis: a case report.

    Primary malignant pericardial mesothelioma is a rare tumor and the case reported here presented as constrictive pericarditis. The patient's symptoms progressed day by day despite treatment with digitalis, diuretics and catecholamines. Although a computed tomographic scan of the chest, echocardiography and pericardiocentesis were performed, a preoperative definitive diagnosis could not be obtained. Emergency pericardiectomy and partial resection of the tumor were carried out with the aid of a percutaneous cardiopulmonary supporting system, but the patient died of cardiac failure on postoperative day 3. The tumor appeared to be the biphasic type of diffuse malignant mesothelioma. The prognosis for pericardial mesothelioma is extremely poor due to its late presentation and difficulty in completely removing it surgically and, unfortunately, there still is not a radical therapy for this tumor.

10/142. Malignant pleural mesothelioma presenting as spontaneous pneumothorax: a case series and review.

    BACKGROUND: Malignant pleural mesothelioma (MPM) is thought to arise from the mesothelial cells that line the pleural cavities. Most patients initially experience the insidious onset of chest pain or shortness of breath, and it rarely presents as spontaneous pneumothorax. case reports: We report four patients who presented in this manner. Three of the patients were exposed to asbestos directly or indirectly at shipyards during world war ii; the fourth was exposed as an insulator's wife. Two of our cases were not recognized to have MPM on histologic examination at first thoracotomy and remained asymptomatic for 12 and 22 months, respectively. In none of the patients described herein, was spontaneous pneumothorax the cause of death. CONCLUSIONS: Since many people were exposed to asbestos during and after world war ii, spontaneous pneumothorax in a patient with the possibility of such exposure should raise the suspicion of malignant pleural mesothelioma.
