Agranulocytosis Associated with Waldenström Macroglobulinemia

Abstract

Currently, there are only 2 case reports of Waldenström macroglobulinemia (WM) associated with severe neutropenia. This is a case report of a woman with a past medical history of WM who presented with neutropenic fever. The patient’s febrile neutropenia resolved after RCD chemotherapy (cyclophosphamide 750 mg/m², dexamethasone 20 mg, and rituximab 375 mg/m²). Fourteen days after administration, the neutrophil level had started to rise and normalized after 6 days. To the best of our knowledge, this is the 3rd reported case of agranulocytosis due to WM.
