Final answer:
Tumor cells in mantle cell lymphomas will show CD5 and CD20 cell markers. The most common presentation in patients includes enlarged lymph nodes, fatigue, weight loss, night sweats, and gastrointestinal symptoms.
Step-by-step explanation:
In the case of mantle cell lymphomas, tumor cells will show two specific cell markers: CD5 and CD20. CD5 is a cell surface antigen associated with T cells, while CD20 is a marker found on B cells. The presence of these markers helps in distinguishing mantle cell lymphomas from other types of lymphomas.
The most common presentation of mantle cell lymphoma in patients includes enlarged lymph nodes, fatigue, weight loss, night sweats, and gastrointestinal symptoms. It is important to note that the presentation can vary from person to person.
