Arteritis
Arteritis is the inflammation of the walls of arteries, usually as a result of infection or autoimmune response. Arteritis, a complex disorder, is still not entirely understood. Arteritis may be distinguished by its different types, based on the organ systems affected by the disease. A complication of arteritis is thrombosis, which can be fatal. Arteritis and phlebitis are forms of vasculitis. Symptoms of general arteritis may include: Inflammation Fever Increased production of red blood cells (erythrocytes) Limping Reduced pulse Diagnosis of arteritis is based on unusual medical symptoms.
Thromboangiitis obliterans
Thromboangiitis obliterans, also known as Buerger disease (English ˈbɜːrɡər; ˈbʏʁɡɐ) or Winiwarter-Buerger disease, is a recurring progressive inflammation and thrombosis (clotting) of small and medium arteries and veins of the hands and feet. It is strongly associated with use of tobacco products, primarily from smoking, but is also associated with smokeless tobacco. There is a recurrent acute and chronic inflammation and thrombosis of arteries and veins of the hands and feet.
Purpura
Purpura (ˈpɜːrpjʊərə) is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin secondary to platelet disorders, vascular disorders, coagulation disorders, or other causes. They measure 3–10 mm, whereas petechiae measure less than 3 mm, and ecchymoses greater than 1 cm. Purpura is common with typhus and can be present with meningitis caused by meningococci or septicaemia.
Giant cell
A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many important physiological roles. Osteoclasts are a type of MGC that are critical for the maintenance, repair, and remodeling of bone and are present normally in a healthy human body.
