Late appearance of acanthocytes during the course of chorea-acanthocytosis

Abstract

A case of chorea-acanthocytosis (CA) syndrome is described. The presence of acanthocytes has usually been considered an important diagnostic marker of CA. However, it is not specific and other neurological diseases have to be considered. In the present report we rule out other diagnostic possibilities and show that the acanthocytes in the peripheral blood smears can appear even later during the course of the disease.
