[A granulocytic sarcoma of right uterine adnexa region as an extramedullary relapse in a patient with chronic myeloid leukemia.].

Granulocytic sarcoma of the uterine adnexa is a rare event. A 50-year-old woman, who had previously been diagnosed as chronic myeloid leukemia (CML), but had a complete hematologic response, presented with lower abdominal pain and a large pelvic mass involving the right uterine adnexa region and extending to the right posterior wall of the bladder and right distal ureter. A biopsy of the uterine adnexa revealed granulocytic sarcoma, and a subsequent bone marrow biopsy confirmed the diagnosis of CML in the blastic phase.
