A typical immunophenotyping report by flow cytometry and immunohistochemistry report on tissue biopsy of MCL will be positive for CD5 (a T‐cell‐associated antigen), CD20, CD19, FMC7, sIgM/sIgD, CD22, CD79b and strongly Cyclin D1, and negative for CD23 (a key cell surface molecule for B‐cell activation and growth) and CD10 (a germinal centre‐associated antigen). Here, MME is linked to mantle cell lymphoma.
