The morphological subcategories of acute monocytic leukemia (M5a and M5b) share similar immunophenotypic and cytogenetic features and clinical outcomes.

Acute monocytic leukemia (M5) is a subtype of acute myeloid leukemia (AML) with two distinct morphologic subcategories, M5a and M5b. We compared the immunophenotype, cytogenetics and clinical outcome of AML M5 with non-M5 AML and also compared M5a with M5b. One hundred and twelve M5 (76 M5a, 36 M5b) and 726 non-M5 cases were identified and treated on protocols at our institution.

Association between Breus' mole and partial hydatidiform mole: chance or can hydropic villi precipitate placental massive subchorionic thrombosis?

Breus' mole (massive subchorionic hematoma) is a rare entity most often found in the placentae of macerated stillborn fetuses. Previously considered to represent a postmortem event, recent evidence suggests that it occurs prior to fetal demise. A 23-week gestation male neonate was delivered of a 23-year-old gravida 3, para 2 woman and survived for 49 min.
