A 53-year-old white man underwent a left pneumonectomy for alveolar cell carcinoma. His postoperative course was complicated by pneumonia. At a follow-up clinic visit, the patient complained of a "roaring sound" during respiration. A follow-up PFT did not show the expected loss of volume (nitrogen washout) from a preoperative PFT, suggesting a bronchopleural fistula. A chest x-ray film and xenon lung scan confirmed the diagnosis. The fistula was surgically repaired.

While chlorine gas inhalation has previously been reported to cause temporary mucous membrane irritation, acute pneumonitis, pulmonary edema, and transient bronchospasm, there is controversy about the existence of long-term pulmonary sequelae. We report the case of a 25-year-old man in whom chronic, recurrent asthma developed after exposure to a chlorine gas leak in an enclosed space. His course since the exposure has been notable for frequent exacerbations necessitating chronic corticosteroid therapy and multiple hospitalizations. To our knowledge, the persistence of symptoms years after the exposure is unique in the literature.

A 17 year old male was admitted because of pancytopenia. Bone marrow aspiration revealed myelodysplasia, no increase of blast cells and excessive expansion of megakaryocytic lineage. Although mild increase of bone marrow reticulin fiber was observed, no hepatosplenomegaly was recognized. Therefore he was diagnosed as refractory anemia (RA) or MDS with myelofibrosis and treated with low dose Ara-C regimen. Remission was achieved in June 1987, but the relapse occurred in Oct. 1987. His bone marrow at the relapse showed more remarkable dysplastic change than before. Sequential bone marrow examinations thereafter, revealed an increase of megakaryocytic lineage, especially immature dysplastic megakaryocytes, leading to the appearance of the abnormal megakaryoblasts (detected with anti GP IIb/IIIa antibody) as well as uncharacterized blast cells in his terminal stage. Transformation from MDS to megakaryocytic leukemia was strongly suggested. He died of severe pneumonia in March 1989. The invasion of abnormal immature megakaryocytic cells including megakaryoblasts was observed in liver, spleen and lymph nodes at autopsy. There are several reports on cases having a common hematological features such as 1) pancytopenia in peripheral blood, 2) myelodysplasia, 3) excessive growth of megakaryocytic lineage, 4) myelofibrosis without hepatosplenomegaly, although other clinical features were different. We propose all these cases should be reviewed at the point of MDS mainly involved in megakaryocytic lineage.

Leiomyoma of the trachea and bronchus is a rare tumor. Only 45 cases have been reported in the Japanese literature. We report here a case of leiomyoma of the intermediate bronchus which was successfully operated on. A 45-year-old man suffered from a repeated episode of pneumonia in the right lower lobe. Bronchoscopy revealed a polypoid mass on the intermediate bronchus. The diagnosis of leiomyoma was made by bronchoscopic biopsy. Sleeve resection of the intermediate bronchus including the tumor and end-to-end anastomosis was performed. His postoperative course was uneventful and bronchoscopic findings showed clear healing of the anastomotic site. The resected specimen contained a tumor with smooth surface having protrusion into the bronchial lumen with 6 x 5 x 4 mm in size. The final pathological diagnosis was leiomyoma of the intermediate bronchus with no evidence of malignancy.

The ventral tegmental area (VTA) is the major dopaminergic (DA) center responsible for the innervation of the prefrontal cortex, nucleus accumbens, and entorhinal region. These areas have been causally implicated in schizophrenia. Thus, the existence of brainstem pathology could explain many of the previously reported findings in schizophrenic (SC) patients. The authors focus on uncovering brainstem abnormalities in schizophrenia by studying the autopsied material of a patient having an early onset of symptomatology. The patient was evaluated at the age of 10 years for manneristic behavior, a speech disorder, and violence. Prominent auditory hallucinations became apparent years later. His mental status and ability for self-care steadily deteriorated until he succumbed to pneumonia at age 22. Microscopic examination of the brain showed central chromatolysis of neurons and mild gliosis in a restricted distribution of the brainstem and thalamus. Cell loss and cytoarchitectural disruption were evident in the frontal lobes, prepyriform cortex, and entorhinal region. The neuropathological changes were interpreted as a chronic derangement in the function of neurons of the rostral brainstem tegmental area and medial thalamus with secondary involvement of their terminal projection sites.

A 43-year-old man was admitted to our hospital because of cough and dyspnea. His chest X-ray showed bilateral basal infiltrative shadows. The increased eosinophils in BAL suggested chronic eosinophilic pneumonia (CEP), whereas the TBLB specimens showed findings compatible with desquamative interstitial pneumonia (DIP). The open lung biopsy specimens showed typical findings of DIP with a peripheral zone, suggestive of CEP. These two diseases may be only phasal differences of reaction to the same extrinsic stimulation.

A 77-year-old man was diagnosed as having acute myelomonocytic leukemia (M4) with increased ringed sideroblasts in the bone marrow (BM) in October, 1979. Complete remission was achieved and ringed sideroblasts disappeared after two courses of CMP (cytarabine, 6-mercaptopurine, prednisolone) therapy. Following remission, there was no increase of blasts during the course of the disease, but monocytosis and dysmyelopoiesis persisted for about seven years. The monocytosis was controlled by 6-mercaptopurine. In June, 1986, however, monocytosis in peripheral blood (PB) and BM developed again, and there was severe pancytopenia and reappearance of ringed sideroblasts without increase of blasts. The patient died of pneumonia on September, 1986. Postmortem examination revealed hypercellular marrow with a few blasts, leukemic cell infiltration into spleen, liver and lymph nodes, ad lung cancer. His clinical and hematological features after remission of acute leukemia accorded with those of CMMoL. The dysmyelopoiesis observed in this case in not induced by anti-leukemic agents, but originated from the same clone as the initial AMMoL, and his disease was thought to be CMMoL converted from blastic crisis to chronic phase.

A 58 year-old man was admitted to our hospital with complaints of dyspnea and cough. Chest X-ray examination revealed diffuse nodular shadow, infiltration in the left upper and lower lobes, and volume loss. BALF showed increased number of cells, particularly eosinophils (65.6%). Eosinophilia (17-13%) was also seen. The histological examination of the TBLB specimen revealed irregular thickening and edema of alveolar septa. From these findings together with clinical features the case was diagnosed as eosinophilic pneumonia. Oral administration of prednisolone started with 30 mg. Within a week, eosinophilia in peripheral blood decreased to 1%, PaO2 increased to 87.5 Torr in room air, and CRP became negative. His chest X-ray film showed the disappearance of infiltrative shadows in the left upper and lower lobes. On the 19th day was prednisolone decreased to 20 mg. Laboratory data and chest roentgenogram showed exacerbation, and PaO2 gradually decreased to 62.9 Torr. Patchy shadows were seen in the right upper lobe. The dose of prednisolone was again increased to 60 mg/day, and was quite effective. The drug dosage was tapered by 10 mg/10 days to 40 mg/day, however all data exacerbated again. The clinical course seemed peculiar for eosinophilic pneumonia, however small reticulonodular shadows on chest X-ray did not change. Therefore, open lung biopsy was performed. The histology of the specimen showed fibrosis, lymphocyte infiltration and thickening of alveolar septa. The clinical course and histopathological findings led to a diagnosis of idiopathic pulmonary fibrosis accompanied with chronic eosinophilic pneumonia.

A 73-year-old man had been treated with Aprindine because of paroxysmal atrial fibrillation. On July 13, 1987, five months after the commencement of aprindine administration, he developed dyspnea and low grade fever. His chest X-ray revealed multiple infiltrative shadows in both lung fields. He was treated by various antibiotics, but the infiltrative shadows increased. BALF showed increased percentage of lymphocytes and a decrease in the OKT4/T8 ratio, and the histological findings of TBLB carried out on August 6, 1987, showed alveolitis with Masson bodies. The lymphocyte stimulation test by drugs was positive only for aprindine. After cessation of Aprindine administration, his complaints and laboratory data improved, but his abnormal shadow on chest X-ray did not diminish completely. Open lung biopsy was performed for differential diagnosis of BOOP, on Sep. 14, 1987. The histopathology of specimens of the lung was compatible with drug-induced pneumonitis. The administration of 30 mg of prednisolone was started on Oct. 14, 1987, and the dosage was decreased gradually. The abnormal shadow on chest X-ray improved. To our knowledge, there has been no reported case of Aprindine-induced pneumonitis, and this could be the first report.

A 63-year-old man was admitted to our hospital with tremor and somnolence, followed soon by coma. Anemia and retinal bleeding were observed. The blood smear exhibited rouleaux formation and leukoerythroblastosis. A bone marrow aspiration resulted in dry tap. The biopsy specimens revealed remarkable infiltration of myeloma cells with fibrosis. The M-component of IgG-lambda type and hyper-ammonemia were detected in the serum. Liver and renal functions, however, were within normal range. His consciousness recovered after plasmapheresis. Two courses of VMCP (vincristine, melphalan, carboquone and prednisolone) did not affect the paraproteinemia. Five courses of VAD (vincristine, adriamycin and dexamethasone) could lower the level of IgG. He died of pneumonia. The plasma of some patients with multiple myeloma may contain unidentified factors which increase the plasma ammonia.
