A 70-year-old male, underwent left lower lobectomy due to lung cancer, had an extremely rare form of left pulmonary artery branching. His pulmonary artery supplying to lateral and posterior basal segments (A9 + 10) was arisen anteriorly from the root of the left pulmonary artery in the mediastinum and ran below in the anterior portion of the upper lobe stem bronchus. Embriologically, this abnormality might be due to a derangement of anastomosis between the pulmonary arch system and splanic plexus in primitive lung, and was interpreted as one of the pulmonary sequestration. Clinically, particularly at thoracotomy, the presence of a large vessel in an unexpected location is very hazardous, so that preoperative pulmonary angiography is useful to detect the abnormal branching.

We report herein the case of the 71-year-old man with lung cancer and pulmonary emphysema requiring supplementary oxygen at 21/min by nasal cannula for whom thoracoscopic wedge resection of an adenocarcinoma in his left lower lobe was successfully performed. During the same procedure, thoracoscopic laser ablation of pulmonary bullae was also carried out. There were no postoperative complications, and the patient is currently well 12 months following surgery without any evidence of local or regional recurrence, or distant metastasis. His severe dyspnea on exertion improved, and he no longer requires supplementary oxygen.

A 67-year-old male was admitted to our hospital because of lung cancer and interstitial pneumonia. Cisplatin, vindesie and mitomycin C were administered for treatment of lung cancer. The leucocyte-counts declined to 1700/microliter on the eighth day after the chemotherapy. Though granulocyte colony-stimulating factor was administered, pain in the right thigh and high grade fever developed. Because Staphylococcus aureus was isolated from the blood specimen, piperacillin was administered. But the high grade fever continued and the pain was expanded to the right hip, left hip, thigh and leg. Because a computed tomograph of the lower limbs showed low density areas in bilateral gluteus maximus muscle right adductor magnus muscle, left biceps femoris muscle and left soleus muscle and the culture of an aspirate from abscess of right leg detected S. aureus, multiple muscular abscesses of the lower limbs was confirmed. We changed the antibiotics from PIPC to imipenem/cilastatin and minocycline on nineteenth day after the chemotherapy. His symptoms improved after the change of antibacterial agents. But he died of acute exacerbation of interstitial pneumonia, after about two months of the chemotherapy. Muscular abscesses of the limbs are very rare in Japan. Only four cases with muscular abscess of the limbs were reported in Japan, since 1988. This case suggests that a muscular abscess must be considered in the differential diagnosis of fever in patients with neutropenia.

Mutagenicity of 15 nitrated polycyclic aromatic hydrocarbons (nitro PAHs), which were detected in ambient air particles and/or combustion source emissions, were examined using a set of six Salmonella typhimurium tester strains (TA7001 to TA7006), and the mutational specificity was characterized by the comparison of the mutagenic potencies of nitro-PAHs in the tester strains. Each strain carries a unique missense mutation in the histidine operon and is reverted by only one specific base-substitution out of six possible changes. All nitro-PAHs tested were mutagenic in multiple strains, and were classified into four categories based on the strains predominantly reverted. 1-Nitropyrene (1-NPy), 2,7-dinitrofluoren-9-one and 1,3-, 1,6- and 1,8-dinitropyrene isomers exerted the highest mutagenicity in strain TA7005 (C.G-->A.T transversion) followed by strain TA7006 (C.G-->G.C transversion). 2- And 3-nitrofluoren-9-one isomers, 2-NPy and 2,7-dinitrophenanthrene were also markedly mutagenic in strain TA7005 but not in strain TA7006. For 2-, 3- and 9-nitrophenanthrene isomers, 2-nitrofluoranthene (2-NFT) and 4-NPy, TA7004 (G.C-->A.T transition) was the most responsive strain. 3-NFT was unique, showing the highest mutagenicity in strain TA7002 (T.A-->A.T transversion). All nitro-PAHs tested induced C.G-->A.T transversion, which is observed as the most frequent base-substitution mutation of p53 tumor suppressor gene in human lung cancer.

A 52-year-old male had an abnormal shadow on a chest X-ray film. His parents were first cousins. His father, brother and two sisters had been diagnosed with Werner's syndrome. His lung lesion was diagnosed as lung cancer and right upper lobectomy was carried out. Histopathological examination of the resected specimen revealed bronchiolo-alveolar carcinoma with independent atypical adenomatous hyperplasia in the alveolar zone. The alveolar structures were those seen in aging lungs, suggesting a close relationship between Werner's syndrome and cancer development.

A 69-year-old man visited in the department of ophthalmology of this university, complained with exophthalmos. He was pointed out hypercalcemia and transferred to the department of endocrinology. The chest X-ray and thoracic CT showed a large mass in lower lobe of the left lung. Cytological diagnosis of this tumor was squamous cell carcinoma. In clinical examination, serum CA was 12.2 mg/dl in spite of normal level of PTH, calcitonin, 1 alpha, -25 (OH) 2D3 and uric cAMP. On the other hand, PTHrP-intact in serum was 9.8 pmol/l. His thyroid gland had no abnormality in palpation or roentogenological examination. The thyroid functions, thyroglobulin, thyrotropin receptor antibody, thyroid test and microsome test were all in normal limit. From these results, he was diagnosed of lung cancer with humoral hypercalcemia of malignancy and euthyroid "isolated" Graves' ophthalmopathy. Left lower lobectomy with mediastinal lymph node dissection (R 2 a) was done and p-stage was IIIA. After operation, serum Ca decreased in normal level and the exophthalmos was also improved gradually. He was in well until 10 months after operation, and died with multiple lung metastases and hypercalcemia. Exophthalmos was also recurred in his terminal stage. Similar case could not find in literature and some discussion of the literatures was mentioned.

A 71-year-old man was referred to us with diplopia, left peripheral facial nerve dysfunction, ataxic gait and dysesthesia of the extremities. Neurological examination revealed mild reduction of sensation to pinprick and light touch in the left dominant lower leg. His standing position was wide based, and he showed Romberg's sign. The patient also presented signs of left peripheral facial, bilateral abducent, and left oculomotor nerve dysfunction. Serum levels of CEA, CA 19-9, and proGRP were high. 67Gallium scintigraphy showed an accumulation of radioactivity at the hilum of the right lung, and the findings of bronchofiberscopy were compatible with the diagnosis of small cell lung cancer. Because the symptoms gradually worsened to the point that the patient could not move by himself, chemotherapy and radiotherapy were initiated 3 months after the onset of symptoms. While under chemotherapy, symptoms of neuropathy subsided and the patient was able to walk with the aid of a walking stick. Although all symptoms were indicative of carcinomatous neuropathy, no antineuronal antibodies were detected in the patient's serum by immunohistochemical techniques. However, because the lung cancer deteriorated gradually despite therapy, the patient died of respiratory failure. At autopsy, tumor metastases were found in the pericardium, left lung, both adrenal glands, right hilum lymph nodes, and mediasternal lymph nodes. No microscopic signs of metastases were found in the frontal, parietal, temporal, or occipital lobes, or in the basal ganglia, thalamus, midbrain, pons, cerebellar vermis and hemispheres, or upper medulla. Histopathologically, there was no degeneration of neuronal cell bodies in cerebellar or cervical dorsal root ganglia; however, almost total loss of myelinated fibers or variegated demyelination of myelinated fibers was observed in the anterior, lateral and posterior funiculus at both cervical segments of the spinal cord. The number of myelinated fibers was smaller in the 5th and 6th cervical left ventral roots. The reason why the patient's symptoms subsided during chemotherapy was probably a suppression of antineuronal antigen by chemotherapy and the repair of myelinated fibers.

A case of pulmonary histoplasmosis, which is rare in Japan, is reported herein. A 43-year-old man who had worked in Mexico for 2 years and had come back to Japan 3 months earlier, presented at our hospital because of an abnormal shadow on his chest roentogenogram with no symptoms. His chest roentogenogram as well as chest computed tomograms revealed a 2-cm-diameter nodule in the anterior basal segment of his right lung and an enlargement of the subcarinal lymph node. Although these pictures seemed to indicate an advanced lung cancer, no malignant cells were found based on the brushing cytology findings after bronchoscopy. An exploratory thoracoscopic tumor resection and biopsy of the enlarged lymph node led to a histological diagnosis of an abscess due to histoplasma. The hospital course was uneventful. Postoperatively, amphotericin B was administered for 1 year. This is the eighth case of pulmonary histoplasmosis reported in Japan. A pulmonary nodule together with mediastinal lymphoadenopathy seems to be characteristic in these patients. Histoplasmosis should therefore be considered in the differential diagnosis, since overseas travel has now become common-place for the Japanese.

Myocardial involvement by malignant neoplasm is rare and often not clinically manifested. The diagnosis is usually made only at autopsy. A 71-year-old man with squamous cell lung cancer presented with chest discomfort. His electrocardiogram was diagnostic of acute myocardial infarction. However, because of the lack of classic symptoms and signs of acute myocardial infarction and normal serum levels of cardiac enzymes, an echocardiography was performed before initiation of thrombolytic therapy. The echocardiography showed a huge hyperechoic mass located in the posterolateral aspect of the left ventricle with myocardium invasion. Thrombolytic therapy was withheld. In patients with lung cancer, an electrocardiogram representative of acute myocardial infarction can rarely be induced by myocardial involvement with lung cancer.
