Mantle cell lymphoma, extranodal and solid organ sites

Mantle cell lymphoma (MCL) is a rare and aggressive subtype of non-Hodgkin lymphoma that arises from the mantle zone of the lymph nodes. This type of lymphoma is characterized by the overexpression of cyclin D1 protein, which promotes the uncontrolled growth and division of lymphocytes.

While MCL typically affects the lymph nodes, it can also involve extranodal and solid organ sites. Extranodal involvement refers to the spread of cancerous cells outside of the lymphatic system, while solid organ involvement refers to the spread of cancerous cells to organs such as the liver, spleen, or bone marrow.

Extranodal involvement of MCL can occur in various organs and tissues, including the gastrointestinal tract, spleen, bone marrow, and skin. The most common extranodal site involved in MCL is the gastrointestinal tract, with up to 50% of MCL patients presenting with this form of involvement. Other sites of extranodal involvement include the central nervous system, lung, and breast.

Solid organ involvement of MCL is less common than extranodal involvement, but it can still occur in up to 20% of cases. The most commonly affected solid organ is the liver, followed by the spleen, bone marrow, and lung. Solid organ involvement of MCL is often associated with a poorer prognosis than lymph node involvement, as it can be more difficult to treat and may result in more severe symptoms.

Overall, the involvement of extranodal and solid organ sites in MCL can significantly impact the prognosis and treatment options for patients. It is important for healthcare professionals to be aware of these potential sites of involvement and to consider them when developing treatment plans for MCL patients.
