Abstract

The association of primary salivary gland non-Hodgkin's lymphoma (NHL) and immunosialadenitis (myoepithelial sialadenitis, MESA) is well recognized. Within MESA the whole spectrum of lymphoproliferation starting with a prelymphoma transforming into an early lymphoma and later on into a manifest lymphoma can be observed. These lymphomas represent so-called low grade B-cell lymphomas of mucosa associated lymphoid tissue (MALT), an entity also including lymphoplasmocytoid immunocytoma according to the Kiel classification of NHL. In a few patients a transition into a high grade B-cell lymphoma may occur. The recognition of early stages of lymphomas and their distinction from reactive MESA is only possible by application of immunohistological methods.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
