What is polycythemia vera? Polycythemia vera, often abbreviated as PV, is a disease that results from an abnormality of a very immature cell in the bone marrow, the site in which all blood cells are made.

The physician may discover an enlarged spleen through the physical examination or an imaging procedure of the abdomen. The disease also may be detected as a result of a medical examination for a blood ...
