However, Acute megakaryoblastic leukemia (M7) recently included in the French-American - British (FAB) classification for acute leukemias [1] is a rare hematological BM MGG (200×). This bone marrow smear is from a 71-year-old woman with AML -M7.

The clinical, hematologic, and histologic features of acute megakaryoblastic leukemia are described for an 8-year-old female Domestic Shorthair cat, a 3-year-old female mixed-breed dog, and a 3-year-old male German Shepherd Dog. The neoplastic cells were characterized as belonging to the megakaryocytic lineage.
