Abstract
BACKGROUND A total of 75% of patients with Sjögren's syndrome are complicated with pulmonary lesions, of which 12% are lymphoma and 6% are amyloid nodules; the coexistence of both is considered to be rare. CASE PRESENTATION A 67-year-old female with Sjögren's syndrome presented with multiple pulmonary nodules on chest computed tomography. Since a definitive diagnosis by transbronchial biopsy was not obtained, wedge resection of the nodules was performed. Pathologic diagnosis revealed eosinophilic deposition that stained positive with Congo red. In addition, lymphoepithelial lesions and lymphocytic infiltration were observed. Lymphocytes with monoclonal proliferation predominantly had κ chain. Based on these findings, the nodules were diagnosed as mucosa-associated lymphoid tissue (MALT) lymphoma with amyloid deposition. CONCLUSIONS The combination of these diseases is very rare, and this is the sixth resected case to the best of our knowledge.

Abstract
Primary systemic amyloidosis is not easily diagnosed. The immunoglobulin deposits are usually localized in the kidney, heart, and liver. We describe an unusual case of a patient suffering from a pericardial amyloidoma with internal calcifications and air bubbles that compressed the right ventricle and shifted the heart to the left. Since the patient was in shock, urgent pericardiotomy was performed. This site showed PET uptake. A monoclonal component was present. On these findings, differential diagnoses included multiple myeloma and atypical pericardial tuberculosis, whereas a periumbilical fat tissue biopsy demonstrated amyloidosis. A previous Salmonella species infection had most likely stimulated the production of amyloid. The patient received bortezomib/dexamethasone treatment and achieved a good response.

Abstract
Pulmonary amyloidosis is a rare disease that incorporates deposition of amyloid microfibril material in the lung parenchyma. The condition generally presents as an indolent subacute-to-chronic pulmonary disease and requires tissue biopsy to establish the diagnosis. Nodular pulmonary amyloidosis, a subtype of pulmonary amyloidosis, is characterised by special radiographic and pathological features. While the disease can be associated with inflammatory conditions; its association with mucosal-associated lymphoid tissue (MALT lymphoma) is unusual and carries management challenges. Herein, we illustrate a case study of nodular pulmonary amyloidosis associated with underlying MALT lymphoma in a patient with known systemic lupus erythematosus. The aim of this article is to share the management experience of this complex condition with the medical community and to conduct an up-to-date literature review on nodular pulmonary amyloidosis.

Abstract
Nodular pulmonary amyloidosis is a very rare form of localized amyloidosis involving the lung, with very little known about its nature. It is usually associated with indolent B cell lymphoproliferative disorder and also connective tissue disorders. No definite treatment guideline exists. Many patients respond to chemotherapy with low risk of progression and a 'wait and watch' strategy is also considered a valid treatment option. In this report the authors present a case of nodular pulmonary amyloidosis with pulmonary mucosa associated lymphoid tissue (MALT) lymphoma that presented with features of metastatic malignant disease and after definitive diagnosis decided not to undergo treatment.

Abstract
Primary pulmonary lymphomas represent a pathologically heterogeneous group of disorders that often share imaging features, which include peribronchovascular nodules and masses or areas of nonresolving consolidation. Primary mediastinal B-cell lymphoma is an extranodal non-Hodgkin lymphoma seen in younger patients that has imaging and pathologic features that demonstrate some degree of overlap with Hodgkin lymphoma. Primary lymphomas of the pleural space are rare and associated with concomitant viral infections.

Abstract
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.

Abstract
Systemic amyloid light chain amyloidosis (AL amyloidosis) is usually seen in association with a plasma cell disorder. Amyloid deposition associated with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a rare phenomenon that is not typically associated with systemic AL amyloidosis. We describe the unusual case of a patient with an adnexal mass secondary to MALT lymphoma with associated amyloid deposition.

Abstract
Lymphoproliferative disorders (LPDs) may involve intrathoracic organs in patients with autoimmune disease, but little is known about the radiologic manifestations of autoimmune disease-associated LPDs (ALPDs) of the lungs. The purpose of our work was to identify the radiologic characteristics of pulmonary involvement in ALPDs. A comprehensive search for PubMed database was conducted with the combination of MeSH words. All articles which had original images or description on radiologic findings were included in this analysis. Also, CT images of eight patients with biopsy-proven lymphoproliferative disorder observed from our institution were added. Overall, 44 cases of ALPD were identified, and consisted of 24 cases of bronchus-associated lymphoid tissue lymphoma (BALToma), eight cases of non-Hodgkin's lymphoma (NHL), six cases of lymphoid interstitial pneumonia (LIP), two cases of nodular lymphoid hyperplasia, two cases of unclassified lymphoproliferative disorder, and one case each of lymphomatoid granulomatosis and hyperblastic BALT. Multiple nodules (n = 14, 32 %) and single mass (n = 8, 18 %) were the predominant radiologic manifestations. The imaging findings conformed to previously described findings of BALToma, NHL, or LIP. Data suggest that BALToma, NHL, and LIP are the predominant ALPDs of the lung, and ALPD generally shared common radiologic features with sporadic LPDs. Familiarity with ALPDs and their imaging findings may enable radiologists or clinicians to include the disease as a potential differential diagnosis and thus, to prompt early biopsy followed by appropriate treatment.

Abstract
We report two cases of thyroid mucosa-associated lymphoid tissue (MALT) lymphoma with associated amyloid protein deposition. While other primary thyroid neoplasms sush as medullary carcinoma and plasmacytoma with associated amyloid protein are known to occur and have been previously described by fine-needle aspiration cytology (FNAC), to our knowledge, the current cases are the first of thyroid MALT lymphoma with amyloid deposition to be detailed in the cytopathology literature. Case 1 was a 73-year-old female with chronic thyroiditis. FNAC suspected MALT lymphoma. The amyloid material was not noticed, nevertheless it existed. Case 2 was a 71-year-old female with a nodule of the thyroid. Malignant lymphoma and medullary carcinoma were suspected by FNAC. The possibility of medullary carcinoma was excluded by a measurement of serum calcitonin and carcinoembryonic antigen. After follow-up for two years, the nodule was diagnosed as MALT lymphoma associated with plasma cell differentiation and amyloidosis by the fourth FNAC. When we encounter small round cell tumors associated with amyloid in thyroid FNAC, we should consider not only medullary carcinoma but also MALT lymphoma.

Abstract
CONTEXT Diagnosis and classification of lymphomas are based on the morphologic, immunologic, and genetic features that the lesional cells share with their normal B and T lymphocyte counterparts. Primary pulmonary lymphomas account for 0.3% of primary lung neoplasms and less than 0.5% of all lymphomas. OBJECTIVE To describe and summarize the clinical and histopathologic features of the primary pulmonary lymphoma and secondary involvement of the lung by lymphoma. DATA SOURCES Peer-reviewed published literature and personal experience. CONCLUSIONS Diagnosis of clonal lymphoid proliferations in the lung has evolved owing to the greater utility of molecular and flow cytometric analysis of tissue. Further studies are needed to best define the clinical and prognostic features, as well as search for targeted therapy for these patients with rare neoplasms.

Abstract
INTRODUCTION Pulmonary amyloidoma or nodular amyloidosis is a localized form of amyloidosis, which can mimic a bronchopulmonary carcinoma. This form of amyloidosis may be associated to an infectious, a systemic disease or a lymphoma. OBSERVATION We describe the case of a 36-year-old patient whose past medical history was consistent for a diabetes mellitus and a hypothyroidism treated by medical treatment. The patient presented a Gougerot-Sjögren syndrome and was explored for non-specific respiratory symptoms. Physical examination was normal. Laboratory tests revealed a monoclonal pic of immunoglobulin. Radiologic findings showed bilateral pulmonary nodules associated to mediastinal lymph nodes. A pulmonary biopsy was performed. Histologic examination revealed a tumoral nodule containing an abundant eosinophilic material, which was acellular and surrounded by a dense lymphomatous infiltrate destroying the pulmonary parenchyma. Histochemical and immunohistochemical study revealed an association of a nodular pulmonary amyloidosis with a MAT pulmonary lymphoma complicating a Gougerot-Sjögren syndrome. CONCLUSION The association of MALT pulmonary lymphoma and localized amyloidosis is rarely observed in case of Gougerot-Sjögren syndrome. The pathogenesis of this association remains unknown and the management non-consensual because of the rarity of the cases reported. Whereas, it appears that localized amyloidosis associated to a MALT lymphoma seems to have a better prognosis than a disseminated amyloidosis.

Abstract
Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma is a mature B-cell neoplasm that typically follows an indolent clinical course. Amyloid deposition associated with MALT lymphoma is uncommon. We describe the clinical and pathologic features of 20 cases of MALT lymphoma and associated amyloid deposition across diverse primary sites. Frozen section immunofluorescence performed on 4 cases suggests that these deposits are a localized form of AL amyloid. Clinical follow-up was available for 15 patients. Amyloid deposits distant from the initial site occurred in 5 cases, always at sites also involved by the underlying lymphoma. No definitive evidence of systemic amyloidosis affecting the heart, kidneys, or liver was present in any patient. Given the generally indolent clinical behavior of MALT lymphomas with associated amyloid, we do not recommend extensive follow-up testing for systemic amyloidosis or more aggressive therapy than would be indicated for other MALT lymphomas of similar clinical stage.

Abstract
We report an unusual pathological finding, a large-sized bubbling appearance of the glomerular basement membrane (GBM), in a patient with pulmonary limited AL amyloidosis and a past history of lupus nephritis. The first renal biopsy specimen from 10 years ago, when systemic lupus erythematosus was diagnosed, demonstrated mild mesangial proliferation and subepithelial deposits (WHO classification: III + V). Light microscopy of the current biopsy using periodic acid methenamine silver (PAMS) stain demonstrated a large-sized bubbling appearance of the GBM; however, very weak immunoglobulin and complement deposition was observed in immunofluorescence studies. Routine electron microscopy demonstrated partial subendothelial expansion with electron-lucent materials, but no electron-dense deposits or amyloid fibrils. Electron microscopy with PAMS stain revealed electron-lucent endothelial scalloping, including some cellular components and microspheres in the GBM; however, it is not clear if these materials are derived from endothelial cells. One possibility is that these unique findings represent a recovery phase of lupus membranous nephritis; another is that these findings correspond to a new disease entity.

Abstract
Light chain (AL) amyloidosis has a rare association with non-Hodgkin lymphoma (NHL). Both peritumoral and systemic AL amyloidosis have been reported, but a detailed description of these syndromes is lacking. We describe 10 patients with lymphoma associated AL amyloidosis. NHL patients with peritumoral amyloidosis had low or undetectable levels of monoclonal (M) protein, mostly single organ involvement(lung or soft tissue), and underlying extranodal marginal zone lymphoma, mucosa associated lymphoid tissue subtype. NHL patients with systemic amyloidosis had high levels of M-protein, multiorgan involvement with frequent cardiac involvement, and predominantly underlying lymphoplasmacytic lymphoma. Systemic amyloidosis was associated with inferior outcomes

Abstract
A 77-year-old man was found to have an abnormal shadow on chest X-ray. Chest CT indicated four lesions in both lungs. One was located in the left S1+2. The others were located in the left S3, right S8 and S9, and those had cyst-like structures. The tumor in S1+2 showed diffuse proliferation of atypical lymphocytes, which were positive for CD20. The diagnosis of pulmonary mucosa-associated lymphoid tissue lymphoma was made. The tumor in S3 was composed of eosinophilic amorphous deposits. The diagnosis of amyloidosis was confirmed by polarized light examination. After oxidation with permanganate solution, the Congo red staining disappeared.
