1/1367. Mucinous cystadenoma of the lung.

    A 56-year-old male patient came under our observation when a peripheral round mass in his right lung which he had since 1991 and which was believed to be a bronchogenic cyst, showed a volumetric enlargement of 2 cm. After performing a lobectomy of the middle lobe, the histopathological examination revealed the presence of a mucinous cystadenoma of borderline malignancy.

2/1367. Lessons from an unusual case: malignancy associated hypercalcemia, pancreatitis and respiratory failure due to ARDS.

    A 37-year old woman, presenting with severe hypercalcaemia-associated pancreatitis with pseudocyst formation, was admitted to intensive care because she developed ARDS with respiratory failure. Skeletal metastasis from non-small cell bronchial carcinoma were subsequently diagnosed. After she developed arterial occlusion in the lower limb, supportive treatment was withdrawn. Severe pancreatitis is an exceedingly unusual presentation of non-small cell bronchial carcinoma. Concepts of diagnostic and therapeutic strategies in the context of suspected unusual pathology, and the concept of futility are briefly discussed.

3/1367. Bronchioloalveolar carcinoma with metastasis to the pituitary gland: a case report.

    An unusual case of metastatic bronchioloalveolar carcinoma of the lung presented as a pituitary tumour in a young adult Chinese female, who subsequently died after having undergone trans-sphenoidal resection. Metastatic cancers of the pituitary are uncommon even in necropsy series and rarely give rise to clinical symptoms. This case draws attention to the fact that, although uncommon, pituitary metastases have been noted with increasing frequency and their distinction from primary pituitary tumours is often difficult. A metastatic pituitary tumour may be the initial presentation of an unknown primary malignancy, wherein the metastatic deposits may also be limited to the pituitary gland. Clinicians and pathologists alike should consider a metastatic lesion in the differential diagnosis of a non-functioning pituitary tumour.

4/1367. Primary pericardial mesothelioma with cardiac tamponade and distant metastasis: case report.

    Although cardiac tamponade is a well-known complication of malignancy, it is uncommon as the initial manifestation. The antemortem diagnosis is difficult and distant metastasis is extremely rare. The presentations of primary pericardial mesothelioma are nonspecific. Pathologically, mesothelioma is the most common in primary tumors of the pericardium. Radical surgery can be used to treat a localized mesothelioma. However, the therapy for advanced primary pericardial mesothelioma is usually palliative because it is resistant to irradiation, and chemotherapy does not markedly improve the outcome. The prognosis is uniformly poor. The median survival from the onset of symptoms is 6 months. We present a 67-year-old woman with cardiac tamponade 4 months prior to a definitive diagnosis of primary pericardial mesothelioma. A computed tomogram confirmed multiple well-enhanced nodules in the pericardium, lungs and liver. Unfortunately, the patient died of multiple organ failure.

5/1367. Extraneural metastasizing ependymoma of the spinal cord.

    This paper reports a case of the rare entity of an extraneural metastasizing ependymoma of the spinal cord. The tumor which arose in the conus medullaris and in the cauda equina was first diagnosed in 1956 when a thoracolumbar myeloresection was performed. At autopsy, 40 years after the primary diagnosis, a massive local tumor recurrence with extraneural metastases in the lungs, the pleura, the liver, and the thoracal and abdominal lymph nodes were found. Immunohistochemical stains of the extraneural metastases showed a strong cytoplasmatic expression of glial fibrillary acidic protein (GFAP). Neither the primary tumor nor its metastases showed any of the conventional morphological criteria of malignancy. Reviewing the literature we discuss the possible mechanism of extraneural tumor spread and the incidence of metastases with regard to the tumor type.

6/1367. Primary adenoid cystic carcinoma of skin with lung metastasis.

    Primary cutaneous adenoid cystic carcinoma was first reported in 1975. We report a case of this malignancy with pulmonary metastases in a 70-year-old man and offer a brief review of the literature.

7/1367. Double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes: report of a case.

    A case of double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes is reported. A 73-year-old man with hemosputum was found to have a mass in his right lower lung field on a chest X-ray. Based on a diagnosis of lung cancer, a right middle and lower lobectomy with a dissection of the lymph nodes was performed. Microscopically, a well developed granulomatous reaction was seen in the dissected mediastinal and hilar lymph nodes. Three years after the pulmonary resection, he was admitted to our hospital because of dysphagia. A diagnosis of lower esophageal cancer was made. A lower esophagectomy with a total gastrectomy was performed. A sarcoid-like reaction comprising epithelioid cells and giant cells was seen in the regional lymph nodes. No clinical findings indicative of systemic sarcoidosis were observed. This rare condition may therefore help to improve our overall understanding of the relationship between malignant neoplasms and sarcoid-like reactions in the regional lymph nodes.

8/1367. Epstein-Barr virus-associated leiomyosarcoma of the thyroid in a child with congenital immunodeficiency: a case report.

    We report an unusual case of multifocal leiomyosarcoma involving the thyroid gland, liver, and right lung in a child with congenital immunodeficiency disease. The smooth muscle nature of these neoplasms was confirmed by immunohistochemistry and electron microscopic studies. in situ hybridization showed large amounts of Epstein-Barr virus messenger rna within the tumor cells. Although Epstein-Barr virus-associated smooth muscle tumors have been reported in children with AIDS and after organ transplantation, we are unaware of any case report in congenital immunodeficiency disease.

9/1367. Unilateral lung volume reduction in preparation for contralateral pneumonectomy.

    A case of staged trans-sternal unilateral lung volume reduction (LVR) on the right followed by contralateral pneumonectomy for a locally advanced left lung malignancy is presented. The predicted symptomatic and functional benefit offered by LVR was felt to be necessary before the removal of the left lung. The patient, a 50-year-old male, with a history of chronic air flow limitation secondary to bullous emphysema, underwent a left pneumonectomy six weeks following a right LVR procedure for poor pulmonary function secondary to generalized emphysema. On admission, forced expiratory volume in 1 s (FEV1) was 1.37 L, 47% of predicted with an FEV1/forced vital capacity of 56%. Five weeks after the unilateral LVR, the patient's FEV1 was 1.85 L, and one year postdischarge from hospital, FEV1 was 0.9 L. One year after discharge, the patient did not require oxygen support, and was active and free of malignant disease.

10/1367. Pulmonary intravascular lymphomatosis: presentation with dyspnea and air trapping.

    Intravascular lymphomatosis (IVL) is a rare lymphoid neoplasm that is typically of B-cell lineage and characterized by proliferation of malignant cells within small arterioles, capillaries, and venules. We report a patient with pulmonary IVL who presented clinically with progressive dyspnea, fever, and a dry cough. Pulmonary function tests revealed a marked decrease in diffusion capacity with airflow obstruction and severe air trapping. High-resolution CT (HRCT) of the chest with inspiratory and expiratory images revealed mosaic attenuation consistent with air trapping. Transbronchial biopsies revealed the diagnosis of IVL with capillary expansion in the alveolar and peribronchiolar interstitial tissue. IVL should be considered in the differential diagnosis of a patient with an interstitial lung disease, air trapping on pulmonary function tests, and mosaic attenuation on HRCT. Transbronchial biopsies may be the initial diagnostic procedure of choice.
