Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is a heterogeneous category of nodal and extranodal mature T-cell lymphomas. PTCL-NOS is a highly aggressive lymphoma, and its prognosis is poorer than those of aggressive B-cell lymphoma such as diffuse large B-cell lymphoma(DLBCL). Current standard chemotherapies for aggressive B-cell lymphoma, such as CHOP, are the commonly used ...

RATIONALE Diffuse large B cell lymphoma (DLBCL) is a malignancy of the B cells with extranodal primary involvement being estimated at 30% to 40% of cases. Primary skeletal muscle presentation of DLBCL is extremely rare, with an estimated incidence of about 0.5% of extranodal lymphomas, presenting mostly in the lower extremities. The possible mechanisms of muscle involvement of DLBCL include pri...

PURPOSE To assess the clinical pattern, the histopathological findings, the response to treatments, the recurrence pattern and the prognosis of malignant lymphoma in the ocular adnexa. METHODS This study was performed on 22 total eyes from 17 patients who were diagnosed with ocular adnexal malignant lymphoma. We retrospectively analyzed the medical records for patient information including th...

Nasal extranodal natural killer/T-cell lymphoma, which is a highly aggressive disease, is more frequently seen in Asia than in Western countries. No consensus has been reached on the management of the disease and the survival depends on the stage of the disease. Localized NK/T-cell lymphoma often responds to radiotherapy well. However, patients with advanced disease or recurrence after chemorad...

Extranodal nasal-type natural killer (NK)/ T-cell lymphoma is rarely observed in children and adolescents. We aim to investigate the clinical features, prognosis, and treatment outcomes in these patients. Thirty-seven patients were reviewed. There were 19, 14, 2, and 2 patients with stage I, stage II, stage III, and stage IV diseases, respectively. Among the patients with stage I and II disease...

Clinical, histologic, cytogenetic, and molecular genetic data of 31 patients with extranodal, nodal, and splenic marginal zone B-cell lymphoma (MZBCL) are presented. Despite these variable clinical manifestations, a similar spectrum of morphologic features as well as distinctive immunophenotypic findings were noted. In all cases, a monotypic B-cell proliferation consistently negative for CD5, C...

Very often, the first doctor who examines a patient with malignant lymphoma is an ENT specialist, because non-Hodgkin lymphoma is five times more frequent than Hodgkin disease in the head and neck region. Approximately 25% of extranodal lymphoma occurs in the head and neck and extranodal presentation is twice as frequent as nodal presentation. This paper present a study of the patients from ENT...

Mucosa associated lymphoid tissue (MALT) lymphoma is a lymphoid neoplasm arising in extranodal sites with histologic features similar to those of nodal marginal zone lymphoma. Among the sites where a primary MALT lymphoma arises, the GI tract is the most common whereas the breast represents only 4%. Bilateral involvement of the breasts by a primary MALT lymphoma is exceptional with only 10 case...

When extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue (MALT), a low grade B-cell lymphoma, arises in the lung it is referred to as bronchus-associated lymphoid tissue (BALT) lymphoma. We describe a patient with a history of Sjögren's syndrome and rheumatoid arthritis with dyspnea and imaging consistent with lymphoid interstitial pneumonia (LIP). However, while histo...
