Hematoma

Image:Myk-haematoma.jpg Image:Hematome-p1000482.jpg A hematoma, or haematoma, is a collection of blood, generally the result of hemorrhage. Hematomas exist as bruises(ecchymoses), but can also develop in organs.

Hematomas can gradually migrate, as the extravasated cellsand pigmentmove in the connective tissue. For example, a patient who hurts the base of his thumb might cause an hematoma which will slowly move all through the finger within a week. Gravityis the main determinant of this process.

Hematomas on articulationscan reduce mobility of a member and present roughly the same symptoms as a fracture.
