A1 Ali, Moaath K. A1 Sabha, Marwa M. YR 2015 UL http://smj.org.sa/content/36/2/239.abstract AB We report a 64-year-old lady with stage II, Immunoglobulin-G lambda multiple myeloma (MM) (standard risk), who presented with type-B lactic acidosis (LA), and multi-organ dysfunction associating myeloma progression, and ending in imminent death. In the context of literature review of all previously reported similar cases, this report highlights and discusses the association of type-B LA and MM (especially progressive disease), and also emphasizes the poor outcome. Early recognition of this condition with intensive supportive care, and treatment of multiple myeloma may improve outcomes.
