11/824. Multifocal peripheral bronchial carcinoid tumour.

    Peripheral bronchial carcinoids sometimes arise as single solid or nodular lesions in the periphery of the lung. We encountered a 74-year-old Japanese male with bronchial carcinoids that were widely disseminated throughout the lung parenchyma. Pulmonary function tests revealed mild airflow obstruction. A metastatic process was ruled out from primary malignancy and a histological examination revealed findings consistent with a peripheral bronchial carcinoid. Based on these findings, we concluded that this patient had a primary multifocal peripheral bronchial carcinoid. An immunohistochemical examination revealed immunoreactivity for chromogranin a and bombesin. The present case appears to be an unusual case of diffuse multifocal peripheral bronchial carcinoid, confirmed by immunohistochemistry. ( info)

12/824. Successful thrombolysis for massive pulmonary embolism after pulmonary resection.

    We report the successful use of thrombolysis for acute massive pulmonary embolism 2 days after right lower lobectomy for bronchial adenocarcinoma. Pulmonary angiography revealed extensive clot unsuitable for surgical embolectomy. A bolus infusion of recombinant tissue plasminogen activator produced an immediate improvement in the patient's hemodynamic state. There was substantial blood loss requiring the transfusion of 21 units of blood over the postoperative period. The patient made a successful recovery and remained well at 1 year. ( info)

13/824. Postbronchoscopy expectoration of tumour tissue in lung cancer.

    A case of undifferentiated giant cell type bronchogenic carcinoma in an old man is reported. Following bronchoscopy, the patient expectorated tumour mass tissue in his sputum and was relieved of breathlessness to a great extent. ( info)

14/824. pathology findings with acrylic implants.

    We report the pathological findings in cases of acrylic implants obtained by direct intratumoral injection of polymethyl-methacrylate (PMMA) and N-butyl-cyano-acrylate (NBCA). Direct intratumoral injection of acrylic implants was performed for a variety of primary and secondary bone lesions. These types of treatments have been used at our institution in the last 4 years for 40 vertebroplasty (PMMA) procedures and for nine bone lesions of other locations (PMMA, NBCA). Postmortem histology became available for 1 case of PMMA and for 5 cases with NBCA intratumoral acrylic implants. The pathological findings associated with PMMA and NBCA were evaluated and compared. PMMA exhibited a macroscopic and microscopic rim of tumor necrosis, 6 months after implantation. NBCA exhibited compressive effects on the nearby tumor tissue, however, without signs of significant necrosis outside the acrylic tumor cast. Tumor captured inside the acrylic cast showed extensive to near complete necrosis. Acrylic implants may lead to necrosis when injected directly in tumors. The necrotizing effect may extend beyond the limits of an implant in the case of PMMA. Such an extended effect of PMMA, when compared with NBCA, may be due to the variable toxicity of acrylic implants, including the different degrees of the exothermic reaction during polymerization.

15/824. Polypoid endobronchial Hodgkin's disease with pneumomediastinum.

    We report a 23-year-old man with polypoid endobronchial Hodgkin's disease which presented with intermittent multilobar atelectasis and spontaneous pneumomediastinum. Chest radiograph and CT findings are demonstrated. ( info)

16/824. A case of lung myelolipomatosis in a patient with bronchial carcinoid.

    Myelolipomas are very rare benign tumours composed of an admixture of mature adipose tissue and normal haematopoietic cells. Although they are most commonly found in the adrenal glands, extra-adrenal myelolipomas are documented. We described a case of myelolipoma arising in the lung in a 52-year-old man. The lesion was found incidentally in association with a carcinoid. To our knowledge, this is the second instance of this neoplasm presenting as a lung lesion, and the first case associated with bronchial carcinoid. Pathogenesis and aetiology of myelolipomas are referred to in this paper with special regard to the clinical and pathological findings. ( info)

17/824. Bronchial capillary hemangioma in adults.

    Two cases with capillary hemangioma of the trachea and the left upper lobe bronchus are presented. The adult patients were referred to the hospital because of hemoptysis and cough. The chest radiographs were normal in both cases. The bronchoscopic examination revealed circumscribed lesions with a capillarized surface protruding into the lumen of the trachea and the left upper lobe bronchus, respectively. The lesions were excised in toto with flexible bronchoscopic forceps. The specimens contained typical capillary hemangiomas without any signs of malignancy. Capillary hemangioma in the bronchial tree is an extremely rare benign lesion in adults. Nevertheless, it should be considered as a possible cause of hemoptysis and cough. ( info)

18/824. Amphicrine tumor.

    The term amphicrine refers to cells, and tumors, which show both exocrine and endocrine features. Author s aim was to analyse the characteristics of these neoplasms. 40 suspicious cases were reviewed. Mucin-stains (PAS, diastase-PAS, Stains-all, Alcian-blue), immunohistochemistry (antibodies against Neuron-Specific Enolase (NSE), and chromogranin a (CGA), and electronmicroscopic studies were performed to demonstrate exocrine and/or endocrine features of the tumor cells. By means of these methods, 16 cases turned out to be amphicrine tumors. Among them, there were 4 sinonasal, 1 bronchial, 1 mediastinal, 8 gastrointestinal and 2 suprarenal gland neoplasms. In connection to the subject, a brief review is given of amphicrine tumor, regarding its etiological and pathological aspects. These tumors form a distinct clinicopathological entity and should be separated from both neuroendocrine tumors and adenocarcinomas. ( info)

19/824. Richter's transformation presenting as an obstructing endobronchial lesion.

    A 60-year-old man with chronic lymphocytic leukemia presented to our institution with a recurring lingular pneumonia. On fiberoptic bronchoscopy, the patient was found to have an endobronchial mass obstructing the lingula and left upper lobe. biopsy specimens of the mass demonstrated anaplastic large cell lymphoma consistent with Richter's transformation. Only one case of endobronchial Richter's transformation has been previously reported in the literature. This was described as peribronchial and endobronchial leukemic infiltrates within the bronchial mucosa. We report the first case of an obstructive endobronchial mass secondary to Richter's transformation. The endobronchial mass was treated with a Nd-YAG laser to maintain airway patency while the patient underwent chemotherapy, resulting in complete resolution of the mass within the airway. ( info)

20/824. Mucous gland adenoma of the bronchus: CT findings in two patients.

    Mucous gland adenoma of the bronchus is a truly benign, well defined, intraluminal mass that manifests on CT with air-meniscus sign or abutting the bronchus. We report the CT findings of mucous gland adenoma in two patients. ( info)
