A schistocyte or schizocyte (from Greek schistos for "divided" and kytos for "hollow" or "cell") is a fragmented part of a red blood cell. Schistocytes are typically irregularly shaped, jagged, and have two pointed ends.[1]
Several microangiopathic diseases, including disseminated intravascular coagulation and thrombotic microangiopathies, generate fibrin strands that sever red blood cells as they try to move past a thrombus, creating schistocytes.
Schistocytes are often seen in patients with hemolytic anemia. They are frequently a consequence of mechanical artificial heart valves, hemolytic uremic syndrome, and thrombotic thrombocytopenic purpura, among other causes. Excessive schistocytes present in blood can be a sign of microangiopathic hemolytic anemia (MAHA).
