Clinical report. Primary granulocytic sarcoma: a rare presentation of an ovarian mass

Background: Primary granulocytic sarcoma (GS) only rarely presents with an ovarian mass classified as extramedullary myeloid progenitor tumor cells. Few patients with cases of primary GS survive after systemic chemotherapy.

Objective: To present a case of primary GS treated with complete course of chemotherapy. The patient is currently in complete remission.

Methods: Retrospective review of medical records and comparison with previous case reports.

Results: A 41-year-old woman presented with an ovarian mass of 6 months duration. There was no previous history of hematologic disease or presence of leukemic cells in other organs at the time of diagnosis. Immunohistochemistry confirmed the diagnosis. She received complete course of chemotherapy, after which complete remission was achieved.

Conclusion: A case of primary granulocytic sarcoma of the ovary was successfully treated with chemotherapy. This disease needs careful diagnosis and appropriate treatment for a good outcome.
