Understanding Mediastinal (Thymic) Large B-Cell Lymphoma, Extranodal and Solid Organ Sites

Mediastinal (thymic) large B-cell lymphoma is a rare type of non-Hodgkin lymphoma that typically starts in the thymus gland located in the chest. This type of lymphoma is also known as primary mediastinal large B-cell lymphoma or PMBCL. However, in some cases, it may also occur in other organs of the body, such as the liver, kidneys, and lungs. When it occurs outside the thymus gland, it is referred to as extranodal or solid organ PMBCL.

This type of lymphoma primarily affects young adults, especially women. The most common symptoms of mediastinal (thymic) large B-cell lymphoma include a persistent cough, difficulty breathing, chest pain, swelling in the neck, and fatigue. However, these symptoms are not specific to this type of lymphoma and may also be present in other medical conditions, making it challenging to diagnose PMBCL.

Diagnosing PMBCL typically involves a variety of tests, such as blood tests, imaging tests, and biopsies. A biopsy is the most definitive way to diagnose PMBCL, where a small tissue sample is taken from the affected area and examined under a microscope to check for the presence of cancer cells.

Extranodal or solid organ PMBCL is even rarer than primary mediastinal large B-cell lymphoma and is typically diagnosed after the cancer has spread to other organs. The symptoms of extranodal or solid organ PMBCL may vary depending on the affected organ. For example, if the liver is affected, symptoms may include abdominal pain, nausea, and jaundice, while if the kidneys are affected, symptoms may include blood in the urine, swelling in the legs, and high blood pressure.
