Extramedullary plasmacytoma (EMP) is a rare form of cancer that affects plasma cells, which are responsible for producing antibodies. In EMP, these cells grow uncontrollably and form tumors outside of the bone marrow, typically in soft tissues such as the throat, sinuses, or lymph nodes.
Although EMP is rare, it can occur in anyone at any age. It typically presents as a single tumor, but multiple tumors can occur in some cases. EMP can cause a range of symptoms depending on the location of the tumor, including difficulty breathing, swallowing, or speaking, as well as swelling or pain.
Diagnosis of EMP typically involves a biopsy of the suspected tumor, which is then examined under a microscope to confirm the presence of abnormal plasma cells. Additional tests may be performed to determine the extent of the cancer and whether it has spread to other areas of the body.
Treatment for EMP typically involves radiation therapy or surgery to remove the tumor. In some cases, chemotherapy may also be used to treat the cancer. The choice of treatment will depend on the location and size of the tumor, as well as the overall health of the patient.
The prognosis for EMP is generally good, with a five-year survival rate of around 70%. However, the risk of recurrence is relatively high, so patients will need to be monitored closely after treatment. Follow-up appointments will typically involve imaging tests to check for any new tumors or signs of cancer, as well as blood tests to monitor the levels of abnormal plasma cells.
