Pseudo-Chediak-Higashi anomaly in a child with a hepatic vascular malformation.

A case of a congenital hepatic vascular malformation in a child complicated by disseminated intravascular coagulation and hemolytic anemia is presented. Examination of the peripheral blood disclosed the presence in the leukocytes of giant intracytoplasmic inclusions resembling those of the Chediak-Higashi anomaly. Ultrastructural analysis characterized those inclusions as phagocytosed red cell debris, a result of mechanical destruction of the red cells.
