Facial palsy as first presentation of acute myeloid leukemia.

Granulocytic sarcoma or chloroma is a tumor composed of myeloblast or monoblast. These tumors may be found in any location of the body and occur in 5% of acute myeloid leukemia (AML) cases and are more common in pediatric patients. In this report we describe the case of a 27-year-old male who developed lower motor neuron seventh nerve palsy followed by swelling of the parotid gland. Fine-needle aspiration cytology (FNAC) of the soft tissue swelling revealed scattered blasts, and peripheral smear and bone marrow aspirate examination suggested AML. This is a rare presentation of a granulocytic sarcoma leading to a diagnosis of AML. Copyright 2003 Wiley-Liss, Inc.
