What exactly is a heart attack? Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat-called an arrhythmia-that causes a severe decrease in the pumping function of the heart.
Oncocytoma can be described as a tumor that is mainly constituted out of oncocytes. These are actually epithelial cells, containing excessive quantities of mitochondria. This excess leads to a cytoplasm that is acidophilic and granular.
Sometimes plasmacytoma can be cured. There are two types of plasmacytoma. In isolated plasmacytoma of bone, one plasma cell tumor is found in the bone, less than 10% of the bone marrow is made up of plasma cells, and there are no other signs of cancer. Plasmacytoma of the bone often becomes multiple myeloma.
