M. Grande, CENTRAL-NERVOUS-SYSTEM GRANULOCYTIC SARCOMA IN A PATIENT WITH ESSENTIAL THROMBOCYTHEMIA, American journal of hematology, 51(1), 1996, pp. 64-67
We report a rare case of central nervous system granulocytic sarcoma (
GS) in a patient with essential thrombocythemia (ET). The diagnosis of
GS was established by morphological and cytochemical findings (peroxi
dase and naphthol-AS-D-chloroacetate esterase positivity) of neoplasti
c cells. GS was detected as an intracranial frontal mass 7 months befo
re the transformation of ET in acute myeloid leukemia and relapsed as
two extradural spinal masses during the course of leukemic evolution.
