1/159. Carcinoid tumours presenting as breast cancer: the utility of radionuclide imaging with 123I-MIBG and 111In-DTPA pentetreotide.

    Secondary tumours of any type in the breast are rare. A review of the literature demonstrated only 23 cases of carcinoid tumours with associated breast metastasis, as distinct from primary carcinoid tumours of the breast. Distant metastases from carcinoid tumours are correlated with poor prognosis and survival. Although both primary and metastatic mammary carcinoid tumours are uncommon, the recognition of the true origin of the tumours may be of importance owing to the different clinical management and prognosis of the two conditions. Recently, radionuclide-labelled imaging techniques have been applied to the localization of such lesions, based on isotope uptake by receptors present in these neuroendocrine tumours. We report two new cases of carcinoid tumours with breast metastases, the primaries being in the ileocaecal valve and the bronchus, respectively. The diagnosis of a carcinoid tumour was based on the clinical, biochemical, histopathological and immunostaining features. Furthermore, these patients had both 123I-MIBG and 111In pentetreotide scintigraphy performed. These radionuclides play a useful role in the localization and potentially in the management of carcinoid tumours and their distant metastases.

2/159. Delayed massive hemoptysis after expandable bronchial stent placement.

    patients with lung cancer often develop airway obstruction that necessitates palliative bronchoscopic interventions. Expandable metal stents are increasingly used for this indication. We report a case of fatal massive hemoptysis that occurred 1 week after uneventful bronchial stent placement. Previous treatment with external-beam radiotherapy, brachytherapy, and photodynamic therapy probably contributed to pulmonary artery-bronchial fistulization in this patient. This complication should be kept in mind when considering expandable airway stent insertion in heavily pretreated lung cancer patients.

3/159. Endobronchial metastasis from stomach cancer.

    A young woman presented with a dry cough present during the previous 4 weeks. A chest radiograph demonstrated diffuse interstitial infiltration in both lower lung fields. Fibreoptic bronchoscopic examination revealed multiple 2-3 mm elevated nodules on the bronchial surface and a mucosal biopsy showed extensive subepithelial infiltration of poorly differentiated adenocarcinoma without definite precancerous alteration in the overlying epithelium. Studies for the evaluation of primary tumour focus were performed. Oesophagogastroduodenoscopy showed advanced gastric cancer of Borrmann type III, and mucosal biopsy of the stomach showed poorly differentiated adenocarcinoma. The patient was treated three times with systemic chemotherapy, but her condition deteriorated. Three months after diagnosis, she died of complicated pneumonia. This is a rare case of endobronchial metastasis from stomach cancer. The stomach is an unusual site of endobronchial metastasis from extrathoracic primary malignancy.

4/159. 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.

5/159. 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.

6/159. 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.

7/159. Malignant myxoid endobronchial tumour: a report of two cases with a unique histological pattern.

    AIMS: To present two cases of malignant endobronchial myxoid tumours with a highly distinctive sarcomatoid pattern not previously described at this site, and discuss their histogenesis in relation to previously documented endobronchial neoplasms. methods AND RESULTS: Both tumours presented in young adult females and were purely sarcomatoid with interweaving cords of small uniform, rounded or slightly elongated cells lying within a myxoid stroma. The stroma was alcian blue positive, but sensitive to hyaluronidase in both cases. The tumour cells contained a small volume of periodic acid-Schiff-positive eosinophilic cytoplasm and stained positively for vimentin only, but there also was a prominent background population of CD68-positive dendritic cells. Ultrastructural studies showed that the tumour cells contained an excess of rough endoplasmic reticulum, with some of the cisternae appearing dilated, and scalloping of the cell surfaces, although no intracisternal tubules were identified. CONCLUSIONS: Although the histological pattern was most reminiscent of extraskeletal myxoid chondrosarcoma, the sensitivity of the stroma to pretreatment with hyaluronidase precluded the diagnosis. However, there were similarities with the sarcomatoid component of malignant salivary gland-type mixed tumours of the lung and this tumour possibly represents a variant of a bronchial gland tumour. Despite this uncertainty over origin, this pattern should be recognized as part of the differential diagnosis of myxoid tumours in the lung, as an apparently indolent type of malignant endobronchial neoplasm.

8/159. Two-stage operation for endobronchial lipoma and lung cancer using bronchoscopy and thoracoscopy in an elderly patient with chronic obstructive pulmonary disease.

    We present an 82-year-old man with chronic obstructive pulmonary disease with endobronchial lipoma, obstructing the right lower lobe bronchus, and lung adenocarcinoma in the peripheral lung of the right upper lobe (clinically T1N0M0). The endobronchial lipoma was thus first removed by bronchoscopic snaring forceps and laser therapy, resulting in an improvement of the pulmonary function. One month later, the lung adenocarcinoma was removed using thoracoscopy. The postoperative course was satisfactory, and the patient is now doing well without any tumor recurrence 11 months after surgery. For elderly chronic obstructive pulmonary disease patients with endobronchial lipoma and T1N0M0 lung cancer, a two-stage operation, consisting of bronchoscopic resection followed by a thoracoscopic resection for lung cancer, was found to be a safe and effective method of treatment while maintaining sufficient pulmonary function.

9/159. Successful primary radiation therapy of adenoid cystic carcinoma of the lung.

    Adenoid cystic carcinoma is a distinctive malignant neoplasm generally arising from minor salivary glands, that arises infrequently as a primary tumor in the lung. Surgery has been considered the primary treatment, with radiotherapy generally utilized as adjuvant or palliative treatment. We report a patient in whom primary radiotherapy was sucessfully applied to treat adenoid cystic carcinoma involving the distal trachea, carina, and both main stem bronchi. A total dose of 66 Gy was delivered in 2-Gy fractions over a 7-week period. Clinically and histologically complete remission was achieved without evidence of disease during a 27-month follow up.

10/159. Endobronchial metastases secondary to solid tumors: report of eight cases and review of the literature.

    Endobronchial metastases (EBM) secondaries to extrapulmonary solid malignant tumors are rare. breast, colon and renal adenocarcinomas are the most frequent tumors associated with EBM. Since 1990 we have treated eight patients with EBM secondary to renal adenocarcinoma (three cases), colon adenocarcinoma (two cases), gastric adenocarcinoma (one case), bladder carcinoma (one case) and basal cell carcinoma (one case). Endobronchial lesions were detected by bronchoscopy and their metastatic nature was confirmed histopathologically in all eight cases. We also conducted a review of EBM reporting studies published in English language. The median interval from the diagnosis of the primary tumour was 41 months. Symptoms and radiological findings were indistinguishable from those of primary lung cancer. Five patients were treated with external radiotherapy with symptomatic improvement while two patients had chemotherapy and one patient underwent surgical resection of the metastasis. Systemic treatment was used in six cases with no significant effect on EBM. Median survival after EBM diagnosis was 9 months with one patient surviving 3.5 years and two patients still alive at 1 year. In conclusion, EBM usually represent a late manifestation requiring differential diagnosis from a primary lung cancer. Local treatment may result in symptomatic improvement but prognosis is generally poor averaging 1-2 years in most series.
