A rare case of acute leukemia relapsing with a granulocytic sarcoma causing ectopic pregnancy.

A 33 year old female was admitted to department of obstetric and gynaecology with profuse vaginal bleeding. She was diagnosed with acute myeloid leukemia 3 months ago. Pelvic ultrasound was unremarkable. Since vaginal bleeding persisted despite normal platelet counts low dose methotrexate was administered with the presumptive diagnosis of ectopic pregnancy. A laparoscopic investigation was performed as she did not respond to this treatment which revealed an intraluminal ectopic pregnancy in her right fallopian tube. A pathological specimen was obtained. Granulocytic sarcoma is an infiltrate of immature granulocytic precursor cells in an extramedullary site. To best of our knowledge, this case is the third patient with GS in the fallopian tube and the first case causing ectopic pregnancy.
