Spontaneous remission of acute monocytic leukemia after infection with Clostridium septicum.
Spontaneous remissions of acute myeloid leukemia (AML) have been reported in association with infection. Here, we report a case of spontaneous remission of AML in a 47-year-old Saudi Arabian male patient who presented with a few weeks history of recurrent abdominal pain, vomiting and fever. He was diagnosed with acute monocytic leukemia (AML, FAB M5b) and a perforated bowel. He also had Clostridium septicum bacteremia and thus chemotherapy was deferred. He received supportive therapy and intravenous antibiotics. Six weeks later, he achieved spontaneous and complete remission lasting for about 4 months. The remission and relapse were documented by bone marrow examination. Similarly, previous reports of spontaneous remission of AML were short lived and were followed by relapse and progression.
