A hematoma, or haematoma, is a collection of blood, generally the result of hemorrhage, or, more specifically, internal bleeding. The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify Diseases The International Statistical Classification of Diseases and Related Health Problems 10th Revision ( ICD -10) is a coding of diseases and signs symptoms abnormal findings S00-T14 - Injury (S00-S09 Head ( Superficial Injury of head ( Superficial injury of The Diseases Database is a free Website that provides information about the relationships between medical conditions Symptoms, and Medications. Medical Subject Headings ( MeSH) is a huge Controlled vocabulary (or metadata system for the purpose of indexing journal articles and books Blood is a specialized Bodily fluid that delivers necessary substances to the body's cells such as nutrients and oxygen—and transports Waste products Bleeding, technically known as hemorrhaging / haemorrhaging (see American and British spelling differences) is the loss of Blood from Internal bleeding is Bleeding occurring inside the Body. It can be a serious Medical emergency depending on where it occurs (e Hematomas exist as bruises (ecchymoses), but can also develop in organs.

It is not to be confused with hemangioma which is an abnormal build up of blood vessels in the skin or internal organs. A hemangioma is a Congenital Benign Tumour or Vascular malformation of endothelial cells (the cells that line blood vessels
Hematomas can gradually migrate, as the effused cells and pigment move in the connective tissue. The cell is the structural and functional unit of all known living Organisms It is the smallest unit of an organism that is classified as living and is often called For the drug referred to as "pigment" see Black tar heroin. For example, a patient who injures the base of his thumb might cause a hematoma, which will slowly move all through the finger within a week. Gravity is the main determinant of this process. Gravitation is a natural Phenomenon by which objects with Mass attract one another
