Systemic Aleukemic Reticuloendotheliosis
📋Overview
Systemic Aleukemic Reticuloendotheliosis is a legacy term historically used to describe a rare, aggressive hematologic malignancy characterized by infiltration of malignant histiocytes (macrophage-like cells) in multiple organs without circulating malignant cells in the peripheral blood. It is now recognized as a form of histiocytic sarcoma or related histiocytic neoplasms under modern classification systems. The term 'aleukemic' refers to the absence of malignant cells in the blood despite systemic involvement.
