MCL is a B cell malignancy with unique biological, pathological and clinical features, comprising 3–10% of all non‐Hodgkin lymphomas (NHLs) (Swerdlow,). It was recognised as a specific entity in the revised European‐American classification of lymphoid neoplasms (REAL) classification (Harris,) and is characterized by the chromosomal translocation t(11;14)(q13·3;q32·33), which results in overexpression of the cell cycle protein cyclin D1 (Akiyama,; Campo,).
