ABSTRACT
This chapter deals with occult tissue hemorrhages. Foci of necrosis are usually associated with hemorrhage and/or vascular thrombosis. Venous thrombosis can be associated with disseminated intravascular coagulopathy and/or arterial emboli and/or nonbacterial thrombotic endocarditis. Fever is a well-known manifestation of vascular thrombosis. The usual manifestation of pulmonary infarction is polypnea and/or tachycardia and/or fever. Fever may result from tissue destruction or may accompany the inflammatory reaction secondary to extra-vascular sequestration of blood. Sometimes the fever is the unique manifestation of the infectious focus; more often it is associated with at least one peripheral manifestation, usually skin or joint involvement. Any lesion of anterior and posterior nuclei nuclei can lead to fever. A primary local lesion at the site of inoculation is sometimes present, as a papule or vesicopustule. It is followed by the regional inflammatory and usually isolated, lymphadenopathy, sometimes associated with fever and mild malaise.
