A 70-year-old woman complained of cough, sputum and fever. Chest roentgenogram showed a mass-like lesion with pleural effusion in the left thorax. Bronchoscopy revealed a polypoid lesion at the orifice of left B10 and mucosal swelling of the left lower lobe bronchi. The biopsied material of the polypoid lesion was diagnosed as malignant lymphoma (diffuse small cell type by LSG classification) and the immunohistochemical examination showed monoclonal proliferation of T lymphocytes. The atypical lymphocytes which were positive for T lymphocyte surface marker were detected in the pleural effusion. There was no evidence of metastasis in any part of the body under clinical examinations, and the lung was thought to be a primary site of the lymphoma. The doubling time of tumor was estimated to be 134 days. Four-drug combination chemotherapy resulted in a marked decrease of the tumor size. Immunohistochemical study to determine the subpopulation of lymphoma cells are required for diagnosis of pulmonary lymphoma, because the biological characters of T cell lymphoma might differ from those of B cell lymphoma.

Mediastinal large-B-cell lymphoma with sclerosis is now considered to be a discrete subtype of lymphoma. It probably originates in the thymus, a T-cell organ. Early publications consider this lymphoma as an aggressive disorder with poor prognosis. We studied retrospectively ten consecutive patients with mediastinal B-cell lymphoma with sclerosis seen in the department of hematology. Nine were women. The median age at diagnosis was 38.3 years (16-60). Dyspnea (experienced by 7 patients), chest pain (5) and cough (10) were the most common clinical features at presentation. Superior vena cava syndrome occurred in three patients. Five had infiltration of the chest wall or of the pulmonary tissue. Four patients were in clinical stage I (all bulky > 10 cm), four in stage IIE, one was in stage IIE and one in stage IV (Ann Arbor classification). All patients were treated with intensive chemotherapy, mostly containing cyclophosphamide, doxorubicin, vincristine or vindesine, bleomycin and prednisone, combined with etoposide or teniposide and methotrexate. Nine patients responded well to chemotherapy (tumor reduction > 75%). One patient progressed. Eight patients received involved field radiotherapy (36-40 Gy) after chemotherapy. The two other patients were treated with intensive chemotherapy (BEAC, BCNU, etoposide, cytarabine, cyclophosphamide), followed by autologous bone marrow transplantation. Two patients died: one patient received autologous bone marrow transplantation in partial remission and relapsed after 6 months; the other patient had progressive disease despite chemotherapy, surgery and radiotherapy. Mean follow-up is 54.6 months (15-118) with 8 patients still remaining in complete remission. In patients with mediastinal B-cell lymphoma, tumour localisation is often limited to the thorax.(ABSTRACT TRUNCATED AT 250 WORDS)

A 34-month-old black boy who had contracted acquired immunodeficiency syndrome from his mother presented with fever, vomiting, and cough. He was cachectic, hypertonic, and developmentally delayed. A brain computed tomography scan revealed masses in the left frontal horn, subependymal, and periventricular regions; secondary edema; and hydrocephalus. The differential diagnosis was cerebral lymphoma versus toxoplasmosis. The patient had disseminated Mycobacterium avium-intracellulare infection, lymphoid interstitial pneumonitis, as well as Pseudomonas and Klebsiella pneumonia. He died of respiratory insufficiency 53 days after admission. The autopsy confirmed a primary cerebral B-cell lymphoma, large cell type, which was positive for Epstein-Barr virus, latent phase, by in situ hybridization. Primary central nervous system lymphomas are rare in children, in contrast to adults. To our knowledge, only five well-documented cases of primary cerebral lymphomas in infants and children with acquired immunodeficiency syndrome have been reported previously. The current study shows that these childhood lymphomas are associated with and presumably caused by Epstein-Barr virus and thus have a pathogenesis similar to that of primary central nervous system lymphomas in adults.

We report on a primary mediastinal large B-cell lymphoma with aberrant expression of beta-human chorionic gonadotropin (beta-hCG). The patient, a 33-year-old man, had cough, dyspnea, fever, superior vena cava syndrome, and a mediastinal bulky tumor. A biopsy showed that the latter was characterized by large cells, sclerosis, and compartmentalization. The neoplastic elements expressed CD45, CD20, CD79a and, partially, CD30, whereas they were negative for CD3, epithelial membrane antigen and cytokeratins. Surprisingly, they displayed a clear-cut positivity for beta-hCG. The remaining oncofetal markers applied (PLAP and alpha1-fetoprotein) were negative. Electron microscopy demonstrated the presence of numerous nuclear pockets and the lack of intercellular junctions. DNA analysis by polymerase chain reaction showed clonal rearrangement of Ig heavy-chain genes. The patient responded promptly to the administration of MACOP-B. To the best of our knowledge, this is the first example of B-cell lymphoma showing positivity for beta-hCG; a similar aberrant expression was previously observed only in three Japanese patients with human T-cell lymphotropic virus type I+ adult T-cell lymphoma/leukemia. Because primary mediastinal large B-cell lymphoma has in the past been frequently confused with germ cell tumors, pathologists should be aware of possible beta-hCG expression by lymphomatous cells to avoid the risk of misdiagnosis.

We report a case of pulmonary intravascular lymphoma of large B cell type in a 72-year-old woman. She had a one-month history of fever and dry cough before admission. Chest X-ray revealed ground glass shadow in both lung fields, and the high-resolution CT disclosed centrilobular distribution of ground glass opacities. Transbronchial lung biopsy demonstrated large lymphoid cells in the capillaries of alveolar septa. The tumor cells showed strong immunohistochemical reactivity to CD 20. After combined treatment with CHOP and rituximab, clinical symptoms, laboratory and radiological findings were improved. As with diffuse large B cell lymphoma, CHOP chemotherapy plus rituximab may prove useful as a standard regimen for pulmonary intravascular lymphoma.

This is the first reported case of lymphoproliferative disease presenting with adrenal insufficiency after liver transplantation. A 38-year-old white man was admitted 8 months after transplantation for cryptogenic cirrhosis with fever (38-39 degrees C), chills, cough, and dyspnea. His blood pressure was 100/70 mm Hg, there was pallor of the conjunctiva, and a lymph node was palpable in the left groin. Laboratory analyses revealed the following values: serum sodium concentration (112 mmol/L), potassium (5.4 mmol/L), hemoglobin (7.8 g/L), white blood cell count (7.7 x 10(9)/L), glucose 3.9 (mmol/L), and mildly elevated liver functions. Abdominal ultrasound showed multiple hypoechoic solid-appearing lesions throughout the liver and spleen. Results of a biopsy specimen of the groin node confirmed polymorphic B-cell lymphoma. A negative Epstein- Barr virus screen before transplant became positive. The patient's fever increased to 40 degrees C. He subsequently developed sepsis and later, multiple organ failure. Autopsy confirmed extensive abdominal disease. The adrenal glands had been completely replaced by the tumor. Primary Epstein-Barr virus infection is associated with posttransplant lymphoproliferative disease. Replacement of the adrenal glands with a tumor produces a clinical picture of adrenal insufficiency.

Bronchoesophageal fistulae associated with lymphomas are generally associated with chemo-radiotherapy. We report here an unusual case of lymphoma with a therapy-unrelated bronchoesophageal fistula. Previously, only 10 similar cases have been reported. A 70-year-old male was diagnosed as having gastric diffuse large B-cell lymphoma in May 1998. In January 1999, he noted a cough after eating and drinking. Because of the presence of a febrile temperature, productive cough and dyspnea, he was referred to our hospital and diagnosed as having aspiration pneumonia. Antibiotics did not improve his symptoms. When tracheal intubation was performed with bronchoscopy, a bronchoesophageal fistula was revealed. Malignant lymphoma cells were found around the fistula in the biopsy specimen. The patient died of pneumonia after treatment with airway stenting and chemotherapy. Induction of necrosis by chemotherapy or low blood flow with stenting and dopamine probably caused enlargement of the fistula.

Primary pulmonary lymphomas (PPL) only constitute 4% of extra-nodal, non-Hodgkin lymphomas (NHL), less than 1% of NHL in general, and between 0.5% and 1% of malignant pulmonary neoplasms. Fifty-eight to 87% of cases of this extremely uncommon disease are low-grade B-cell lymphomas and 11%-19% are high-grade or large B-cell lymphomas. The prognosis for.high-grade or large B-cell lymphomas is worse than for low-grade lymphomas; respiratory and general symptoms are usually present. However asthmatic symptoms are not often found in their clinic. We report the case of a 49-year old woman with resistant asthma clinic in the form of wheezing, dyspnea and non-productive painless cough; associated with an irregular lobulated mass with air bronchograms in the lower lobe of the right lung. Histological diagnosis showed a pattern of high-grade B-cell lymphoma and all asthmatic symptoms disappeared following gross total resection of this lesion.

We describe a 68-year-old male patient with diffuse large B-cell lymphoma (DLBCL) who suffered from relapse in bilateral upper lobes of the lung. The patient presented with cough, weakness and fever. A bronchovascular-lymphangitis-like shadow was detected in the bilateral upper lobes on a chest roentgenogram. Although cytological and cytofluorometric examinations revealed no malignant cells in the bronchoalveolar lavage fluid, trans-bronchial lung biopsy (TBLB) showed involvement of DLBCL in the bronchial mucosa. Recurrent lymphoma tends to extend along the bronchovascular bundles, resulting in granulomatous consolidation that may mimic tuberculosis and is likely to involve the lower lobes. Thus, TBLB proved to be essential for the diagnosis of the lung involvement of non-Hodgkin's lymphoma (NHL).

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.
