What is hematology? Hematology is the study of blood and blood disorders. Hematologists and hematopathologists are highly trained healthcare providers who specialize in diseases of the blood and blood components. These include blood and bone marrow cells. Hematological tests can help diagnose anemia, infection, hemophilia, blood-clotting disorders, and leukemia.
Roseola is a viral illness that usually affects children between the ages of six months and two years. It is typically marked by several days of high fever, followed by a pinkish-red flat or raised rash that appears on the child's torso and spreads over the body as the fever breaks.
The term is most commonly used to denote the pigmented area on the human breast around the nipple (areola mammae) but it can also describe other small circular areas such as an inflamed region of skin. The plural of areola is areolas or areolae, which is pronounced /ÉËriËÉliË/ or /ÉËriËÉlaÉª/.
