Abstract:
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 (peroxidase and naphthol-AS-D-chloroacetate esterase positivity) of neoplastic cells. GS was detected as an intracranial frontal mass 7 months before the transformation of ET in acute myeloid leukemia and relapsed as two extradural spinal masses during the course of leukemic evolution.

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
