C32221 Body Part C90259 Pediatric Terminology A C32979 Leptomeninges Leptomeninges The two innermost layers of tissue that cover the brain and spinal cord, the arachnoid mater and the pia mater. C32221 Body Part C90259 Pediatric Terminology A C33470 Retinal Pigment Epithelium Retinal Pigment Eipthelium A continuous, insulating monolayer of cuboidal/columnar epithelium which extends from the margins of the optic nerve head to the ora serrata where it is continuous with the pigment epithelium of the pars plana. This cell layer has many physical, optical, metabolic/biochemical and transport functions which play a critical role in the normal visual process, including acting as a selective filter to determine what nutrients reach the retina from the choroid.

The classification of acute myeloid leukemias (AMLs) encompasses four major categories: 1) AML with recurrent genetic abnormalities; 2) AML with multilineage dysplasia; 3) Therapy-related AML; 4) AML not otherwise specified. The required bone marrow or peripheral blood blast percentage for the diagnosis of AML is 20% (WHO classification). A rapidly progressive cancer of the blood and bone marrow consisting of the proliferation of abnormal myeloblasts, which are immature, dysfunctional white blood cells.
