Marginal zone B-cell lymphoma of the pulmonary mucosa-associated lymphoid tissue type (pulmonary MALT-MZL), a common kind of primary pulmonary lymphoma, is rare in pulmonary malignant tumors. One patient in our hospital was diagnosed by bronchoscope and the literatures on the subject were reviewed. The patient presented with periodical fever, cough and chest pain, and antibiotic therapy had no use. Chest CT scan showed the consolidation of right middle lobe and left lower lobe with CT angiogram signs, air bronchograms and distended bronchi. Pleural effusion in the left thorax mainly consisted of monocytes. Monoclonal protein was found in the electrophoresis of serum protein. Bronchial stenosis and swollen mucosa were seen with bronchoscope. The tissue section of transbronchial lung biopsy (TBLB) specimens showed diffusedly infiltrated small lymphocytes and a lymphoepithelial lesion. CD20 was positive and CD3, CD5, CD10, CD21, CD23, bcl2, bcl6 were negative in immunohistochemical stain. The clinical manifestations of pulmonary MALT-MZL are nonspecific and misdiagnosis is common, Appropriate invasive biopsy procedures are necessary for early diagnosis. Presentations such as periodical fever, distended bronchi in pulmonary consolidation, monoclonal protein might indicate diagnosis. Treatment includes surgical resection, radiotherapy and chemotherapy. Pulmonary MALT-MZL belongs to inert lymphoma and prognosis is relatively good.

Non-Hodgkin's lymphoma (NHL) involving the endobronchial tree is uncommon, and the initial presentation of NHL as an endobronchial tumor is extremely rare. In a series of 441 patients with newly diagnosed non-Hodgkin's lymphoma over a 7-year period, we reviewed the clinical features of eight patients who presented with an endobronchial tumor. All patients had local pulmonary disease without extrathoracic involvement. The major presenting symptoms were dyspnea, chest pain, cough, and hoarseness. None of the patients had systemic symptoms. Radiographs revealed lobar collapse in all cases. Five patients had mediastinal masses and three had isolated endobronchial lesions. Although MALT lymphoma is the most common primary pulmonary lymphoma, it was present in only one of our patients, while seven patients had aggressive lymphoma. All patients received chemotherapy. Six of the eight patients responded favorably to treatment with complete remission. The prognosis of patients with isolated endobronchial lymphoma is not worse than other local presentations of lymphoma. Bronchoscopic examination with biopsy is essential to differentiate these lesions from primary bronchongenic carcinoma.

A 74-year-old man presented with left chest pain. He had been given a diagnosis of sarcoidosis at age 65. Chest CT films on admission revealed a mass shadow in the left lower lung field and a small nodule in the left upper lung field. Because the specimens of transbronchial biopsy were not diagnostic, video-assisted thoracoscopic surgery was performed. The pathologic diagnosis of the resected lung was overlapping cancers (large cell neuroendocrine carcinoma and mucosa-associated lymphoid tissue lymphoma) complicated with sarcoidosis. Adjuvant chemotherapy was not performed. One year after surgery he continues to do well and has no evidence of recurrence.

Mucosa-associated lymphoid tissue (MALT) lymphoma is very rare in children. We report the first case of pediatric thymic MALT lymphoma in an adolescent Asian girl. She presented with chest pain, dyspnea, and low-grade fever. A large anterior mediastinal mass was biopsied that confirmed the diagnosis of MALT lymphoma with trisomy 18. The patient had secondary immunodeficiency with low NK cell count and high IgA and IgG levels. Because of the advanced stage and the presence of trisomy 18, she was treated with cyclophosphamide, vincristine, prednisone, and rituximab, followed by involved-field radiotherapy. She is currently undergoing maintenance therapy with rituximab and remains in complete remission at 13 months from diagnosis. Thymic MALT lymphoma should be suspected in any Asian child with a cystic thymic mass and autoimmune disease or hyperglobinemia. Because of the slow proliferation rate of this type of lymphoma, a long-term follow-up is needed.

The primary pulmonary lymphoma is a rare disease, representing 0.5 to 1% of the malignant lung tumors. In our countries, in spite of the increasing prevalence of the pulmonary tumors, aggravated by smoking and environmental factors, any case report of the primary pulmonary lymphoma is notified. We report a confirmed case of MALT lung lymphoma that is managed in our hospital. Mr. S.B., 68-year-old man, not smoking, without particular professional exhibition, is admitted for a chronic cough with blood-streaked sputum, dyspnea, chest pain and loss of weight. His symptomatology is evolving for 4months. In the examination, the general health was passable and he presented a pulmonary condensation syndrome at right. The physical examination of others systems was normal. There was a biological inflammatory syndrome. The bacteriological examinations of the bronchial expectorations were negative. The chest CT showed bilateral alveolar opacities at the upper, with attraction of the fissures, without nodes. The bronchoscopy showed anomalies of the bronchial mucous membrane in 2 superior lobes. The perendoscopiques biopsies confirmed a MALT lung lymphoma. We did not find other localizations. Chemotherapy was proposed to our patient with favorable evolution. The MALT primary lung lymphoma must not be underestimated. Clinical manifestations and radiological characteristics are no specific and it's necessary to eliminate a lung cancer or tuberculosis in our countries. The difficulties of their diagnostic are intensified by the not availability of an adequate technical tray.

Mucosa-associated lymphoid tissue (MALT) lymphoma is a form of low-grade malignant B-cell extranodal non-Hodgkin's lymphoma. It is classified as marginal-zone lymphoma and represents less than 1% of all lung cancer. We describe a case of MALT lymphoma limited exclusively to the lung that came to our attention with infective pleural effusion and concomitant lung consolidation of the left lower lobe. Our case demonstrates that MALT can begin with an acute clinical presentation. The clinical scenario, with fever, parietal chest pain, and leukocytosis, suggested an infective process. Radiological and sonographic examinations and the endoscopic aspect during medical thoracoscopy (MT) were typical of an infective etiology. The histological outcome of non-specific inflammatory pleuritis confirmed our suppositions. However, the missing resolution of lung consolidation after several weeks led us to an alternative diagnosis. Parenchymal biopsies obtained by bronchoscopy allowed us to reach the correct diagnosis: MALT lymphoma limited to the lung.

Primary lung lymphoma (PLL) is a rare disease that comprises <0.5% of all primary lung tumors. It is defined as lymphoma confined to the lung with or without hilar lymph node involvement at the time of diagnosis or up to 3 months thereafter. Patients with PLL may be asymptomatic or manifest nonspecific clinical symptoms, for example, cough, chest pain, and dyspnea. Some individuals may be immunosupressed or have an autoimmune disorder. Radiologically, PLL can mimic pneumonia, lung carcinoma, or metastasis, and therefore, histologic confirmation is mandatory for definitive diagnosis. Primary lung marginal zone lymphoma of mucosa-associated lymphoid tissue type comprises 70% to 80% of cases. Less common B-cell lymphomas include diffuse large B-cell lymphoma, lymphomatoid granulomatosis (LyG), plasmacytoma, and other small lymphocytic lymphomas. PLLs of T-cell origin, largely represented by anaplastic large cell lymphoma, are extremely rare. LyG is an Epstein-Barr virus (EBV)-driven B-cell lymphoid neoplastic proliferation rich in T cells that produces vasculitis. The disease may present at different stages of progression. Differential diagnosis of PLL varies according to the lymphoma subtype: pulmonary mucosa-associated lymphoid tissue lymphoma should be distinguished from reactive inflammatory conditions, whereas high-grade lymphomas may resemble poorly differentiated lung carcinoma, metastatic disease, and other lymphomas. LyG can resemble inflammatory, infectious, and other lymphoid neoplastic processes. A panel of immunohistochemical markers, flow cytometry, and molecular methods are necessary to confirm the diagnosis in the majority of cases. In this article we review the clinical, radiologic, pathologic, and molecular characteristics of several B-cell and T-cell PLLs with exception of Hodgkin lymphoma and posttransplant lymphoproliferative disorder.

The scientific STAFF and MALT meetings were created around the turn of the century for scientists engaged in enhancing the role of the 12-lead ECG for detection and quantification of involved myocardium in patients with acute coronary syndrome. These meetings were initially focused on computer processing of data from two single-center databases. The STAFF database was collected in the mid-nineties on patients with prolonged total coronary occlusion; high-resolution 12-lead ECGs were collected before, during, and after 5 minutes of occlusion. The MALT database was created in the early years of this century on consecutive patients with chest pain admitted to a large teaching hospital. Delayed enhancement magnetic resonance imaging and electrocardiograms were recorded in these acutely ill patients. The paper highlights the first 2 decades of the STAFF and MALT meetings and details the meeting format.

A 60-year-old female presented with dyspnea, cough, and chest pain with a left hilar mass lesion. In our case, clinicoradiological correlation, bronchoscopy, and computed tomography-guided biopsy revealed the diagnosis of primary pulmonary non-Hodgkin's lymphoma (PPNHL) on histopathology and immunohistochemistry. We discuss the approach to hilar masses. PPNHL is a rare malignant lymphoma most common being mucosa-associated lymphoid tissue lymphoma. Various therapeutic options are available. The chemotherapy regimen consisting of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone) is preferred.

Primary pulmonary lymphoma is a rare entity. Furthermore, simultaneous bilateral spontaneous pneumothorax (SBSP) is a very rare condition which is often related to therapeutic complications. We present, to the best of our knowledge, the first case of primary pulmonary mucosa associated lymphoid tissue (MALT) lymphoma revealed by SBSP. A 50-year-old female was diagnosed with organizing pneumonia. One month later, she presented with sudden chest pain and shortness of breath due to SBSP. Bilateral chest tubes were inserted. A scan- guided right lung biopsy led to the diagnosis of primary pulmonary MALT lymphoma. The patient was treated with R-CHOP chemotherapy. The association between lymphoma and pneumothorax is extremely rare, often related to therapeutic toxicity. We report the case of SBSP as the first manifestation of primary pulmonary MALT lymphoma.
