A variety of Tand B-cell neoplasm can involve the skin and the term “primary cutaneous lymphoma” refers to the disorder that present in the skin with no evidence of extracutaneous disease at the time of diagnosis [1,2]. Among them, primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT) is characterized with skin lesions on one or both legs. In patients presenting with a single ...

Background Although uncommon, mature small B-cell lymphomas may arise in the oral/maxillofacial area and oral pathologists must be aware of key characteristics these neoplasms to perform an accurate diagnosis. In this manuscript, we attempted integrate currently available data on clinicopathological features follicular lymphoma (FL), mantle cell (MCL), extranodal marginal zone mucosa-associated...

Plasmablastic lymphoma (PBL) is a rare form of non-Hodgkin's lymphoma that is associated with human immunodeficiency virus (HIV) infection. Although PBL is most commonly observed in the oral cavity of HIV-positive patients, it can also be observed at extra-oral sites in HIV-negative patients. This report represents an unusual case of HIV-negative PBL that occurred in the sigmoid colon. This pat...

SUMMARY Refractory celiac disease is an uncommon condition which might be associated to poor prognosis. It often treated with immunosuppressive medications, results. divided in type 1 and 2, the latter carrying a high risk for lymphoma mortality. A case of 41 year old female patient refractory 2 reported. She was oral budesonide six months, achieving histological remission.

Plasmablastic lymphoma (PBL), a very aggressive variant of diffuse large B cell lymphoma (DLBCL), has been described initially as a rapidly progressive and almost invariably fatal diffuse large-cell lymphoma with plasmablastic features. Immunohistochemical findings showed generally CD20 antigen negative and VS38c, CD138 and MUM 1 positives. This neoplasm was initially described almost exclusive...

Mucosa-associated lymphoid tissue (MALT) lymphoma is a type of extranodal marginal zone B-cell lymphoma and is a distinct subtype of non-Hodgkin's lymphoma.Primary MALT lymphomas can also occur in the oral cavity, although their appearance in this location is rare. The neoplastic cells of which MALT lymphomas are composed express B-cell antigens and show monotypic immunoglobulin expression with...

Lymphoma is a malignant neoplasm of lymphoid tissue which is divided into 2 groups: Hodgkin and non-Hodgkin. About 85% of non-Hodgkin lymphomas are B-cell lymphomas, and T-cell lymphomas are unusual. Anaplastic large cell lymphoma (ALCL) is a kind of non-Hodgkin lymphoma with T or NK cell origin that is rarely seen in the oral cavity and only 10 cases have been reported up to now. Here we prese...

Doxycycline has antiproliferative effects in human lymphoma cells and in murine xenografts. We hypothesized that doxycycline would decrease canine lymphoma cell viability and prospectively evaluated its clinical tolerability in client-owned dogs with spontaneous, nodal, multicentric, substage a, B-cell lymphoma, not previously treated with chemotherapy. Treatment duration ranged from 1 to 8 wee...
