Catastrophic antiphospholipid syndrome (CAPS) survivors rarely relapse. We herein report a case of a second CAPS episode with an unusual subacute course and no microangiopathic hemolytic anemia (MAHA), a common CAPS symptom. During the first episode, the 69-year-old woman responded well to high-dose glucocorticoids and plasma exchange. On relapse, these treatments plus rituximab were ineffective and she died of multi-organ failure and bacterial cholangitis. The absence of MAHA and a subacute course do not exclude a CAPS recurrence.
