Abstract

We report about a primary Non-Hodgkin Lymphoma (NHL) of the internal auditory canal. The only previously known manifestations of a NHL in the temporal bone have been infiltrations or hemorrhagic complications due to a late manifestation or advanced systemic disease. Involvement of both temporal bones is typical. The 60-year-old female patient complained of an acute one-sided deafness, accompanied by a high-pitched tinnitus, rotating vertigo, and paralysis of the left half of the face. We found a deafness in the left ear, spontaneous nystaxis, which was interpreted as a deficiency in excitement of the vestibular organ, and a complete peripheral facial paralysis. Diagnostic imaging studies revealed a large, intrameatal solid mass in the temporal bone, measuring 1.2 x 0.8 cm. Histologic examination after translabyrinthine tumor removal demonstrated a centroblastic Non-Hodgkin Lymphoma. The following extensive interdisciplinary staging examination showed no other tumor manifestations; the CSF analysis was negative. The uniqueness of this case lies in the detection of a primary nongeneralized centroblastic lymphoma of the internal auditory canal. In contrast to infiltrations of systemic NHL in the same location, in which the advance...Continue Reading

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.

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.
