This is just the work from my memory of the case that i  had seen during my 4 months medical rotation at Hematology Unit.

Patient is a 20 years old college student with no past medical history, presented with severe abdominal pain for 1 week of duration.

Ultrasound reveals ovarymass and subsequent she went for operation.

HPE finding shows granulocytic sarcoma. The diagnosis of granulocytic sarcoma (myeloid sarcoma) is equivalent to Acute myeloid leukemia (AML)

She was referred to Hematology ward and underwent series of chemotherapy and she underwent a stem-cell transplant.  She is a strong lady and at present, she is continuing her study at a local college after a year break.

The case is special because leukemia can actually be manifested in different forms and not necessary in hematological manifestations.

definition from wikipedia:

Myeloid sarcoma (chloroma, granulocytic sarcoma, extramedullary myeloid tumor), is a is a solid tumor composed of immature white blood cells called myeloblasts. A chloroma is an extramedullary manifestation of acute myeloid leukemia; in other words, it is a solid collection of leukemic cells occurring outside of the bone marrow.

Emedicine has information on myeloid sarcoma.

And on the prognostic of the disease

There are no prognostically predictive clinical or pathologic features associated with myeloid sarcoma. The probability of prolonged survival or cure seems higher for patients who undergo allogeneic or autologous bone marrow transplantatio
