Abstract
Splenic rupture leads to massive hemorrhage and requires immediate surgical intervention. Splenic rupture results from trauma or from underlying disease processes. Lymphoma is a rare cause of atraumatic splenic rupture (ASR) with high mortality rates. We present a case of ASR due to T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) requiring splenectomy and large-volume transfusion. This case report highlights the necessity of prompt surgical intervention and massive transfusion for hemodynamically unstable ASR. This report also discusses massive transfusion protocol (MTP) and its limited use in nontraumatic surgical patients.
