Early erythroblastic leukemia. This leukemic blast cell displays
typical ultrastructure. The nucleus contains mainly euchromatin and
prominent nucleolus structures. Characteristic granules called  granules () because they resemble the greek letter theta and
ferritin containing granules (F) are present in the juxta-nuclear
region near the centriole (c). Large size mitochondria (m) and lipid
inclusions (L) are frequent (original magnification ×18,000). (Inset)
High magnification of the characteristic granule ultrastructure.
Ferritin molecules are identified in the granules by their density and
shape (F). granules exhibit complex internal structures (original
magnification ×54,600). (Courtesy of Elisabeth M. Cramer, MD, PhD,
