Granulocytic sarcoma of the hard palate: report of the first case.

A case of granulocytic sarcoma of the hard palate in an elderly woman is presented. The diagnosis was suspected on the basis of histologic findings in routine tissue sections and confirmed by cytochemical and electron microscopic studies. No systemic evidence of myeloid leukemia or of any other myeloproliferative disorder was documented in the patient, who died of an unrelated cause shortly after diagnosis.
