Primary Site(s)

See Module 7
Most common sites of involvement: lymph nodes, gastrointestinal tract, and Waldeyer ring

Coding Manual: Hematopoietic Coding Manual (PDF)

Abstractor Notes

Peripheral blood involvement common, present in almost all patients by flow cytometry. B symptoms in about half of patients.

Most patients present in Stage III or IV. Spleen, bone marrow and liver are common metastatic sites.

Patients presenting with peripheral blood, bone marrow and possibly splenic involvement but without adenopathy are reported to have better prognosis.

Diagnostic Confirmation

This histology can be determined by positive histology (including peripheral blood) with or without genetics and/or immunophenotyping. Review the Definitive Diagnostic Methods, Immunophenotyping and Genetics Data sections below, and the instructions in the Hematopoietic Manual for further guidance on assigning Diagnostic confirmation.

Definition

Mantle cell lymphoma is a mature B-cell neoplasm usually composed of monomorphic small to medium-sized lymphoid cells with irregular nuclear contours.

Leukemic non-nodal mantle cell lymphoma is defined as mantle cell lymphoma in which the patient presents with peripheral blood, bone marrow, and sometimes splenic involvement but without significant adenopathy.

There are several variants of Mantle cell lymphoma

1) Blastoid: An aggressive variant where cells resemble lymphoblasts with dispersed chromatin and a high mitotic rate.

2) Pleomorphic: An aggressive variant where cells are pleomorphic, but many are large with oval to irregular nuclear contours, generally pale cytoplasm, and other prominent nucleoli in at least some of the cells.

3) Small-cell: Cells are small round lymphocytes with more clumped chromatin, either admixed or predominant, mimicking a small lymphocytic lymphoma

4) Marginal zone-like: There are prominent foci of cells with abundant pale cytoplasm resembling marginal zone or monocytoid B cells, mimicking a marginal zone lymphoma, sometimes these paler foci also resemble proliferation centers of chronic lymphocytic leukemia/small lymphocytic lymphoma

Definitive Diagnostic Methods

Genetic testing
Histologic confirmation
Immunophenotyping

Genetics Data

Heavy and light chain genes rearranged, t(11;14)(q13;q32) in virtually all cases, overexpression CYCLIN D mRNA, mutation or deletions of ATM gene

Immunophenotyping

BCL6- (no expression/negative)
CD5+ (expression/positive)
CD10- (no expression/negative)
CD23- (no expression/negative) or weakly positive
CD43+ (expression/positive)
Cyclin D1+ (expression/positive)
FMC7+ (expression/positive)
IgM/IgD+ (expression/positive)
IRF4+ (expression/positive)
MUM1+ (expression/positive)

Treatments
