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.
Plasmacytoma Treatment. A plasmacytoma is a malignant tumor formed by white blood cells. These tumors grow in soft tissue or within bones. Over a 5-10 year period, plasmacytoma that occur in bones can progress to a more serious condition known as multiple myeloma. The majority of cases of plasmacytoma produce a paraprotien that interferes with kidney function. Plasmacytoma that occur in soft tissue are frequently seen in the upper respiratory tract and are very treatable with surgery. Single tumors that are found in bones respond well to radiotherapy.
