Kidney and Pancreatic Extramedullary Relapse in Adult Acute Lymphoblastic Leukemia : A Case Report and Review of the Literature

Abstract EN

Extramedullary relapse of acute lymphoblastic leukemia (ALL) is rare and has been primarily reported in pediatric patients or hematopoietic stem cell transplant recipients.

We report a case of a 62-year-old woman who presented with relapsed ALL involving her kidneys, pancreas, and bone marrow 2 years after completing chemotherapy with a standard ALL protocol.

Unfortunately, her extramedullary disease progressed despite treatment.

To the best of our knowledge, this is the first reported case of extramedullary relapse of B-cell ALL to the kidneys and pancreas occurring in an adult patient who had not previously undergone a hematopoietic stem cell transplant.

A literature review of kidney and pancreatic extramedullary relapse in ALL is also included.
