Spontaneous rupture of the spleen as the presenting feature of the blastoid variant of mantle cell lymphoma.

Spontaneous splenic rupture is rare, and particularly so as the initial presentation of a lymphoproliferative disorder. Although rare cases of splenic rupture have been reported in mantle cell lymphoma there has not been a report of the blastoid variant presenting in this manner. We report such a case in a 64-year-old man.
