Autoerythrocyte Sensitization Syndrome with Thrombocytosis

Abstract

A case of autoerythrocyte sensitization syndrome in a 59-year-old female is reported. She had several episodes of circular ecchymoses on her left thigh. Intradermal injection of autoerythrocytes reproduced a similar ecchymosis. Thrombocytosis was detected and treated with busulfan which induced a delayed improvement of the ecchymosis outbreaks over 2 years of follow-up.
