A 24-year-old woman was admitted to our hospital because of a high fever that had persisted for two weeks. She complained of a sore throat and arthralgia, and had evanescent rash, lymphadenopathy, liver dysfunction, and hyperferritinemia. Tests for RF and ANA were negative. Adult-onset Still's disease was diagnosed. On the fifth day of hospitalization, acute respiratory distress syndrome (ARDS) and disseminated intravascular coagulation (DIC) developed. Treatment consisted of mechanical ventilation and administration of steroid pulse-therapy and gabexate mesilate. Analysis of fluid obtained by bronchoalveolar lavage showed increases in the total cell count, predominantly of neutrophils and lymphocytes. Bilateral pulmonary infiltration seen on chest radiographs was alleviated, and the arterial blood gas data gradually improved. After cyclosporine was given, all the above symptoms associated with adult-onset Still's disease disappeared. Plasma levels of inflammatory cytokines decreased with the improvement of the patient's clinical condition.

There have been only a few reports of bronchorrhea in patients with metastatic pulmonary carcinoma. We report a case of suspected lung metastasis of pancreatic carcinoma with bronchorrhea, which was radiologically similar to bronchioloalveolar carcinoma. A 67-year-old man who had previously undergone surgical resection of pancreatic carcinoma was admitted because of a progressive cough producing copious amounts of serous sputum. A chest radiograph on admission revealed an infiltrative shadow with air bronchograms and ground glass opacities in the left middle and lower lung fields. A chest CT scan revealed a consolidative shadow with air bronchograms and bubble-like lucencies similar to bronchioloalveolar carcinoma in the left lower lobe. The histopathological features of the specimen obtained by transbronchial biopsy revealed adenocarcinoma with a pattern identical to that of the pancreatic carcinoma. Immunohistochemical staining with anti-SP-A antibody was entirely negative but those with anti-CA 19-9, Dupan 2 and CA 50 were positive in both lung and pancreatic tumors. These results strongly suggest that the pulmonary carcinoma was a metastasis of cystic adenocarcinoma of the pancreas. In summary, for a definitive diagnosis of bronchioloalveolar carcinoma, extrapulmonary adenocarcinoma as a primary site should first be ruled out.

A 69-year-old woman with myelodysplastic syndrome (MDS) was admitted to our hospital because of recurrent fever and pulmonary infiltration shadows. On the seventh day of hospitalization, she had an attack of high fever and cough and laboratory tests revealed an elevated leukocyte count and elevated serum C-reactive protein. Chest radiographs showed infiltration shadows in the right middle and lower lung fields. Because a diagnosis of bacterial pneumonia was initially suggested, she was treated with antibiotics. However, the infiltration shadows on the chest radiograph had not improve, so bronchofiberscopy was performed. Analysis of fluid obtained by bronchoalveolar lavage (BAL) showed an increase in the total cell count, predominantly in lymphocytes and neutrophils. A transbronchial biopsy specimen showed infiltration of numerous neutrophils with necrosis under the bronchial epithelium, and edematous septa were infiltrated with numerous neutrophils and lymphocytes. BAL, blood, urine, bone marrow, and sputum cultures were all free of bacteria, mycobacteria and fungi. Interstitial infiltration by numbers of neutrophils associated with MDS was diagnosed and steroid treatment was performed.

We present a case of small cell lung cancer whose shadow resembles bead son chest radiographs. An 81-year-old woman who had been receiving treatment from her doctor for pulmonary emphysema and chronic respiratory failure consulted our department because a small nodular shadow had been detected radiographically in the right lower lung field. The bead-like shadows in the radiographs and tomograms extended from the periphery of the right lower lobe to the pulmonary hilum. This case of small cell lung cancer appeared in chest radiographs to have an unusual shape.

A 19-year old man was admitted to our hospital with fever and productive cough. Chest X-ray films revealed multiple nodular shadows accompanied by a fusing tendency in the right middle field. A diagnosis of bacterial pneumonia was indicated, and the patient was treated with antibiotics. However, because this failed to resolve the nodular shadows, bronchofibroscopy was performed. Examination with a fiberoptic bronchoscope revealed an elevated lesion in the truncus intermedius. Histopathologic examination of a specimen obtained by transbronchial biopsy revealed cryptococcal organisms with the infiltration of monocytes. These findings yielded a diagnosis of pulmonary cryptococcosis with endobronchial lesion. After 6 months of treatment with fluconazole, the multiple nodular shadows disappeared. Comparison of bronchoscopic findings before and after fluconazole treatment clearly demonstrated the efficacy of the therapy.
