Abstract

Lymphomas are the second most common non-epithelial malignant tumors in the oral and maxillofacial region. Non-Hodgkin's lymphoma (NHL) develops at extranodal sites, and cases involving the maxilla account for less than 1% of all NHLs. We describe a case of diffuse large B-cell lymphoma (DLBCL) in the maxilla, and highlight the clinical signs, symptoms, differential diagnosis, and appropriate treatment of DLBCL in the oral cavity and maxillofacial region. A 67-year-old woman was admitted to our surgical department with pain and swelling in her right upper posterior teeth for about six months. She was previously misdiagnosed with periodontal disease and had a history of tooth extraction. Computed tomography (CT) scan revealed extensive osteolysis in the right posterior part of the maxilla with enhanced neoplasm. A solid mass was found upon incisional biopsy, and immunohistochemistry confirmed the diagnosis of DLBCL. The patient was treated with six courses of rituximab, cyclophosphamide, pirarubicin, vincristine, and prednisolone (R-CHOP), followed by external irradiation treatment. The treatment was well tolerated, and the patient is presently alive after two years of follow-up. Non-specific symptoms, such as unclear primary de...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.

Cancer Imaging

Imaging techniques, including CT and MR, have become essential to tumor detection, diagnosis, and monitoring. Here is the latest research on cancer imaging.
