Seventy-one-year-old woman was visited to our hospital because of dry cough and dyspnea on effort. Fine crackle was audible on both lower lung fields. Joints and skin were normal. Laboratory examination revealed elevation of serum LDH and CRP level. Both anti-nuclear antibody and Jo-1 antibody were negative. Blood gas analysis showed hypoxia after exercise. Chest X-ray film showed reticular shadow in both lower lung fields. Chest CT finding showed patchy area of ground glass attenuation, air-space consolidation, and reticular shadow. Scintigram showed diffuse uptake of Gallium-67 in both lung. Transbronchial biopsy specimen revealed alveolar wall thickness, lymphocyte infiltration and swelling of type II pneumocytes. Bronchoalveolar lavage fluid analysis revealed elevation of CD4/CD8 ratio. She was given a diagnosis of idiopathic interstitial pneumonia. Combination therapy of cyclosporin A and steroid was performed. After therapy, her chest CT findings and her data of pulmonary function test were improved. Then therapy of cyclosporin A was continued and dose of prednisolone was gradually decreased. After that, she was suffered from respiratory tract infection. After administration of antibiotics and cyclosporin A, she was getting well without acute exacerbation of interstitial pneumonia. Since then, she was treated with cyclosporin A only and her pulmonary function test data were gradually improved more. It suggests that cyclosporin A may be useful for the treatment of idiopathic interstitial pneumonia.

Pulmonary alveolar proteinosis (PAP) is a rare, diffuse infiltrative lung disease of unknown etiology characterized by accumulation of abnormal lung surfactant in the alveoli and distal airways. Although it was first described in 1958, few large scale studies have been published. The diagnosis is conventionally based on lung biopsy and the value of less invasive procedures such as bronchoalveolar lavage (BAL) remains controversial. A multi-center retrospective study was conducted in an attempt to update epidemiological, clinical and long term outcome and to assess the usefulness of chest CT scan and BAL in the management of a large homogeneous series of 41 patients. Inclusion criteria required a clinical picture compatible with PAP and either histological confirmation, or a BAL with a milky macroscopic appearance coupled with positive staining to PAS. Mean age was 48.8 years with a 4: 1 male predominance. The prevalence of smokers (80%) and occupational exposure to various inhaled dusts (39%) was high. The clinical, roentgenographic and functional features were in keeping with previous series. Worsening dyspnea was the most common symptom. Other common manifestations were dry cough, recurrent lung infections, weight loss, finger clubbing, crackles and cyanosis. LDH serum levels were increased in 51% of cases. Lung function tests usually showed a mild restrictive ventilatory defect with hypoxemia and reduced DLCO. Chest X ray revealed bilateral ground glass opacities with consolidation or air bronchogram involving peri-hilar or lower lobes. Chest CT scan, performed in 38 patients, revealed a similar pattern in most of them with diffuse intra-alveolar ground glass opacities (33/38) and interlobular thickening (35/38), resulting in a crazy paving appearance in the typical geographic pattern (32/38). This latter aspect was highly suggestive of the diagnosis. Segmental BAL led to a definitive diagnosis in 62% and lung biopsy was only required in 38% of cases. These data suggest that careful BAL analysis can be sufficient to provide a diagnosis without the need for a lung biopsy. During follow-up, spontaneous remission or improvement was reported in 26%. Segmental (n=3) or whole lung lavage (n=22) was required in 62.5% with a favorable course (complete remission 37%, improvement 34%, stable course 21%) in 92% of the cases. In this series the overall prognosis for PAP remained good, although unpredictable.

A woman with scleroderma and classic polyarteritis nodosa (PAN) who developed idiopathic myelofibrosis (IM) is reported. The patient presented with a one-year history of weakness, polyarthritis, Raynaud phenomenon, dry cough, and epigastralgia. The diagnosis of scleroderma with visceral involvement was made and treatment with prednisone subsequently started, with good clinical response. Six years later, fever, weight loss, livedo reticularis, and dysesthesias developed. Electromyographic studies were consistent with sensory neuropathy and a sural nerve biopsy yielded the diagnosis of PAN. The patient received cyclophosphamide plus prednisone with a favorable response, but 11 years later she was admitted because of weakness, constitutional symptoms, and abdominal pain due to spleen infarcts. Marked anemia, with aniso-poikilocytosis, tear-drop cells, immature myeloid precursors in the peripheral blood, and an increased serum LDH, was observed and the diagnosis of IM established by bone marrow biopsy. This case represents a new association between IM and an autoimmune disease and supports the hypothesis of an immune basis of IM in some patients.

We encountered three cases of paragonimiasis westermani caused by ingestion of Chinese freshwater crabs. All patients are Chinese living in Japan who had a history of eating raw Shanghai crabs at the Chinese restaurant owned by one of them. A few months later they complained of cough, chest pain and dyspnea. On examination, their peripheral blood showed a remarkable increase in eosinophils. Chest radiographs revealed the presence of pleural effusion in all cases, and of pneumothorax in one. Pleural fluid obtained from two cases showed an increased number of eosinophils, an elevated LDH, and a decreased glucose level. Paragonimus westermani was determined in a positive serum antibody test. The patients were treated with praziquantel for 3 days at a daily dosage of 75 mg/kg and their symptoms were relieved, but one case needed additional treatment with praziquantel for 3 days at a daily dosage of 50 mg/kg because of sustained pleural effusion and a persistently high antibody titer. Most cases of paragonimiasis found in Japan have been sporadic and individual, but three cases occurring close to each other in both distance and time have recently been reported. Such multiple infections are likely to increase because of the gourmet food boom and the internationalization of eating habits. Paragonimiasis must be kept in mind in the differential diagnosis of cases of pleural effusion with eosinophilia. We would therefore like to emphasize the importance of the detection of parasite-specific antibodies and of careful history-taking from patients.

Tuberculous pleurisy has still importance in the group of exudative pleurisy. In this study we aimed to evaluate clinical, radiological, biochemical, bacteriological and histopathological findings of 105 cases with tuberculous pleurisy retrospectively, between January 1999 and December 2002. Female/male ratio was approximately 1/9 and mean age was 32.6 (range: 15-68). The common symptoms were chest pain (75.2%), cough (54.3%) and dyspnea (47.6%). In 17% cases parenchymal lesions were seen in the chest radiography while parenchymal lesions were found 52% of patients by computed tomography. Adenosine deaminase levels in pleural fluid were high in 80% of cases. PPD reactions was found positive in 84.7% of case. Sputum was studied in 52 cases. In 6 (11.5%) patients both ARB and culture were positive but in 4 (7.7%) patients was only culture positive. Pleural fluid ARB examination of all patients was negative whereas culture was positive only in 5 (5%) of patients. In two patients pleural biopsy material culture was positive for ARB. Cytological examination of pleural fluid revealed lymphocyte predominance in 81 (81%) of cases. Eighty one patients had pleural biopsy and pathologic evaluation revealed tuberculosis in 59 (73%) of them. At the end of the treatment 24 (23%) patients had pleural thickening. Pleural fluid LDH level of the patients with pleural thickening was higher than the other patients significantly (p=0.024). It is concluded that, pleural biopsy is the most effective diagnostic method for the tuberculous pleurisy and in the patient with elevated pleural LDH level, pleural thickening seems more.

In 1996 36-year-old man was admitted into our hospital because of polyarthralgia, skin eruptions followed by multiple cutaneous ulcers, dry cough and elevation of C-reactive protein level. The finding of skin biopsy from left elbow was vasculitis. Chest CT showed linear interstitial shadow at bilateral dorsalis lungs. Transbronchial lung biopsy (TBLB) revealed marked infiltration of inflammatory cells in the bronchial walls and peripheral alveoli. In addition, eosinophils were not in branchoalveolar lavage (BAL) fluid. Moreover, video-assisted thoracic surgery (VATS) revealed organizing fibroblastic polyp and bronchiolitis obliterans at terminal bronchiole. We diagnosed his pneumonia as bronchiolitis obliterans organizing pneumonia (BOOP). Administration of oral prednisolone (40 mg/day) was begun and he experienced diminished BOOP and other clinical manifestations. Three years later he developed dry cough, dyspnea and digital ulcers again. Arterial blood gas analysis revealed marked hypoxemia and laboratory studies showed LDH (377 IU/ml) and CRP (8.27 mg/dl) levels were elevated. Chest CT pointed out an exacerbation of BOOP. Treatment with intravenous pulses methylprednisolone and oral prednisolone (60 mg/day) resulted in marked improvement of the clinical manifestations. We describe a rare case of vasculitis associated with BOOP.

Between 1997 and 2002, 107 patients with symptoms of superior vena cava (SVC) obstruction presented at a university hospital in Northeast Thailand. Age averaged 50.7 years (range, 1 to 84). The male to female ratio was 5.7:1. Duration of symptoms before diagnosis was 29.4 days (range, 2 to 240), including facial swelling, cough, and chest discomfort. About 20% of cases developed respiratory failure and 11.2% died shortly after admission. The mean hospital stay was 23.7 days. Anteroposterior and lateral chest radiographs and computed chest tomography helped locate the lesion. Transbronchial biopsy through bronchoscopy, transthoracic needle biopsy under computed tomography, lymph node biopsy, pleural fluid cytology and/or biopsy were used for histopathologic sampling. High levels of alpha-fetoprotein and beta-HCG indicated an anterior mediastinal mass. The most common etiology of SVC obstruction was bronchogenic carcinoma (51.8%), followed by an anterior mediastinal mass (14.5%), lymphoma (13.6%--with an LDH of 262 to 1459 U/l), metastatic cancer (9.1%), and acute lymphoblastic leukemia (1.8%). Benign SVC thrombosis was found in four patients with Behcet's disease or some other idiopathy. Mediastinal fibrosis from melioidosis occurred in three patients, which is rare, has not been previouly reported. Most patients (63.6%) received a combination of radiotherapy and corticosteroid and this helped 55.2% improve.

Primary mediastinal large B-cell lymphoma (PMLBCL) is a unique type of B-cell lymphoma probably arising from a putative thymic medulla B-cell. It constitutes 6-10% of all diffuse large B-cell lymphomas (DLBCL), occurring more often in young females. PMLBCL is characterized by a diffuse proliferation of medium to large B-cells associated with sclerosis and a degree of compartmentalisation. Its main molecular characteristics include: gains in 9p segments, p53 mutations, BCL-2 and MAL gene over-expression, somatic mutations of IgVH genes, BCL-6, PIM-1, PAX-5, RhoH/TTF, and c-MYC, and constitutional NF-kappaB activation. The gene expression signature of PMLBCL seems to be much closer to classic Hodgkin lymphoma than to DLBCL. PMLBCL is characterized by a locally invasive anterior mediastinal mass, often producing cough, chest pain, dyspnea, and superior vena cava syndrome. Most PMLBCL patients have stage I-II, bulky disease, with pleural or pericardial effusions in a third of cases. Systemic symptoms, mainly fever or weight loss, are present in <20% of cases; increased LDH levels are observed in 70-80% of cases. Treatment with CHOP regimen followed by radiation therapy was associated with a 5-year survival of 65%. Apparently better results have been reported with third-generation weekly alternating regimens followed by radiation therapy. Any recurrence is almost always seen in the first 2 years of follow-up, and distant relapses tend to involve extranodal organs. Features associated with poor prognosis are poor performance status, pericardial effusion, bulky disease, high serum LDH at diagnosis, and a compromised dose-intensity of anthracycline and cyclophosphamide.

Bird fancier's or breeder's lung is an unusual hypersensitivity pneumonitis found in pediatric patients, due to avian antigen inhalation. A case of pigeon breeder's lung in a 12 years old child is presented. Clinical symptoms were dry cough for 15 days, dyspnea and weight loss. Physical examination of the patient showed cyanosis, chest tightness, tachypnea, inspiratory crackles and oxygen saturation of 91% in room air. Laboratory data revealed hypergammaglobulinemia and elevated LDH. Pulmonary function testing showed a mixed ventilatory pattern and a decreased carbon monoxide diffusion (DLCO) capacity. Radiological findings were compatible with hypersensitivity pneumonitis, and pigeon IgG antibodies (ELISA) and skin tests with pigeon serum were positive. The child improved with corticoid therapy and antigen avoidance.

A 47-year-old woman was admitted to our hospital complaining of persistent fever and dry cough in June 2007. CT scan showed hepatosplenomegaly. Laboratory data revealed pancytopenia and increased levels of LDH and soluble interleukin-2 receptor. Malignant lymphoma was suspected, but histological diagnosis was difficult because superficial lymph nodes could not be palpated. Histological examination of the bone marrow biopsy specimen demonstrated the proliferation of large atypical lymphoid cells positive for CD20 and CD79a in the small capillaries, leading to the diagnosis of intravascular large B-cell lymphoma (IVLBCL). Although the results of neurological examination and CSF analysis were normal, head MRI showed a T2-hyperintense lesion in the pons. We chose R-hyper-CVAD/R-MTX-Ara-C alternating therapy with MTX intrathecal injection because CNS involvement in IVLBCL was highly suspected, and she responded well. Head MRI showed the disappearance of the abnormal signal in the pons after one cycle of R-hyper-CVAD. Five cycles of R-hyper-CVAD/R-MTX-Ara-C were performed and complete remission was obtained. R-hyper-CVAD/R-MTX-Ara-C alternating therapy was effective in an IVLBCL patient with CNS involvement.
