Myeloblastoma (granulocytic sarcoma) of the ovary.

Myeloblastic neoplasms occur in patients with leukemia. In women, the ovary is a common site. The cells of the tumor are identical histochemically to those in the peripheral blood. The Giemsa stain, PAS stain, and Leder stain assist in the diagnosis. The tumors are responsive to radiation therapy, chemotherapy, and operative removal, but tend to be associated with decreased survival. This report describes a case of myeloblastoma of the ovary in an 18-year-old woman. The clinical and pathologic features of these tumors are described. The literature is reviewed briefly.
