Mantle cell lymphoma is now recognised as a rare but distinct entity in the revised WHO classification. It is now well recognised that MCL represent a broad spectrum of different histopathological subtypes. The term blastic or blastoid variant is generally used to describe cases with a homogeneous population of cells displaying lymphoblastic morphology. The blastic form of MCL may be difficult to diagnose however immunophenotyping and molecular analysis show typical mantle cell lymphoma pattern. We present a case of 30 year old male presenting with inguinal mass which was diagnosed as blastic transformation of mantle cell lymphoma based on routine histopathology and immunohistochemistry.
