A rare presentation of spontaneous splenic rupture from plasma cell leukaemia-a case report.

Spontaneous/atraumatic splenic rupture is rare, and often associated with underlying infectious disease, or haematological malignancy. Plasma cell leukaemia (PCL) is a rare and aggressive subtype of multiple myeloma, with a higher prevalence of hepatosplenomegaly with a bleeding diathesis from secondary to thrombocytopaenia. We report the case of an 82-year-old male presenting to the emergency department with altered mentation and complaints of left abdominal pain. He presented with haemorrhagic shock. Imaging revealed a spontaneous splenic rupture. He underwent emergency laparotomy and splenectomy for which the histopathology yielded a diagnosis of PCL as the cause for rupture. He received four courses of bortezomib and hyperCVAD 1A therapy. After a long 64-day admission, he recovered well and was discharged home with outpatient haematology/oncology follow-up.
