Mantle cell lymphoma
Diagnosis in short

Mantle cell lymphoma. H&E stain.
LM small monomorphic (uniform size, shape and staining) lymphoid population with abundant mitoses, +/-scattered epithelioid histiocytes (should not be confused with tingible-body macrophages), +/-sclerosed blood vessels
Subtypes blastic variant
LM DDx other small cell lymphomas (esp. MALT lymphoma), Burkitt lymphoma
IHC cyclin D1 +ve, CD5 +ve, CD43 +ve, CD20 +ve, CD23 -ve
Molecular t(11;14)(q13;q32) / IGH-CCND1
Site lymph node, GI tract, other sites
Prevalence not common
Prognosis moderately aggressive to poor

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]
  • Rare ~ 2% of non-Hogkin's lymphoma in a series of over 4000 patients.[2]

GI tract - typically:[3]

  • Abdominal pain (~37% of cases) or GI bleeding (~26% of cases).

Gross

  • GI tract: polypoid lesions (~50% of cases).[3]

Microscopic

Features:[4]

  • Typically a small monomorphic (uniform size, shape and staining) lymphoid population.
    • May be "large" (blastic variant of mantle cell lymphoma) with 1 or 2 nucleoli.[5]
  • Abundant mitoses.
  • Scattered epithelioid histiocytes (should not be confused with tingible-body macrophages).
  • Sclerosed blood vessels.

Mantle cell lymphoma Mantle cell lymphoma Mantle cell lymphoma Mantle cell lymphoma Mantle cell lymphoma Mantle cell lymphoma Mantle cell lymphoma
Mantle cell lymphoma in a 56 year old woman. A. A blue sea of cells spares a lymphoid follicle in the upper right corner. B. Small, round to reniform cells contrast with the larger tingible body macrophage (arrow). C-F. Tumor cells are Cyclin D1. CD20, BCL2, and CD5 positive positive. G. About 60% of tumor cells were positive for Ki67. Tumor cells were negative for CD3, CD10, and BCL6.

IHC

  • CD45 +ve.
  • CD20 +ve.
  • CD79a +ve.
  • CD5 +ve -- important.
    • Negative in case reports.[7]
  • CD43 +ve.
  • Cyclin D1 +ve -- key immunostain.

Others:

  • CD23 -ve.
    • Positive in CLL.

Molecular

  • t(11;14)(q13;q32) / IGH-CCND1.[9]

COMMENT:
The tumour consists of small lymphoid cells in sheets.

The tumour stains as follows:
POSITIVE: CD20, CD5, BCL2, cyclin D1.
NEGATIVE: CD23, BCL6, CD10.
PROLIFERATION (Ki-67): 25%.
