Has anyone else had small B-cell non-Hodgkin lymphoma found in the sigmoid colon?
Yes, lymphoma can develop in the colon, though it's relatively uncommon. Non-Hodgkin lymphoma is the most common type of colorectal lymphoma, and B-cell lymphomas are the most frequent subtype affecting the gastrointestinal tract.
About 30 to 40 percent of lymphomas that develop outside of lymph nodes occur in the GI tract. The colon and rectum can be affected, though this represents a small percentage of all colon cancers.
Several types of B-cell lymphomas can affect the colon, including:
- Diffuse large B-cell lymphoma (most common subtype)
- Mantle cell lymphoma
- Follicular lymphoma
- Mucosa-associated lymphoid tissue (MALT) lymphoma
Since your doctor doesn't have experience with this presentation, it may be helpful to seek a consultation with a lymphoma specialist or hematologist-oncologist who has expertise in gastrointestinal lymphomas. They can provide guidance on diagnosis, staging, and treatment options specific to your situation.
