The small cell lymphomas are a collection of commonly seen lymphomas that have a near-identical histomorphologic appearance.
The group includes:
- Small lymphocytic lymphoma/chronic lymphocytic leukemia.
- Follicular lymphoma.
- Mantle cell lymphoma.
- Marginal zone lymphoma (includes MALT lymphoma).
- Hairy cell leukemia.
- Immunoproliferative small intestinal disease (IPSID).[1]
