Mantle cell lymphoma, abbreviated MCL, is less common small cell lymphoma that is relatively aggressive when compared to other small cell lymphomas.
General
- Relatively aggressive - guarded prognosis.[1]
Microscopic
Features:[2]
- Small monomorphic (uniform size, shape and staining) lymphoid population.
- Abundant mitoses.
- Scattered epithelioid histiocytes (should not be confused with tingible-body macrophages).
- Sclerosed blood vessels.
DDx:
- Other small cell lymphomas, esp. marginal zone lymphoma.
- Burkitt's lymphoma.

Others:
