Abstract

Primary lymphoma of the mandible are rare and most often revealed by painless swelling. They are often confused with odontogenic lesions. Hence, their diagnosis is delayed.

They most often come out as a painless swelling, sometimes ulcerated in the mouth. They are often misdiagnosed as a dental problem. Treatment combines variably radiotherapy and/or chemotherapy. The progno...Continue Reading

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.
