An ecchymosis is a hematoma of the skin larger than 10 mm. [2] They may occur among and or within many areas such as skin and other organs , connective tissues , bone , joints and muscle . A collection of blood (or even a hemorrhage ) may be aggravated by anticoagulant medication (blood thinner).
A bruise, also known as a contusion, is a type of hematoma of tissue, [3] the most common cause being capillaries damaged by trauma, causing localized bleeding that extravasates into the surrounding interstitial tissues. Most bruises occur close enough to the epidermis such that the bleeding causes a visible discoloration.
Contusion — Also known as a bruise, this is a blunt trauma damaging tissue under the surface of the skin. Crushing Injuries — Caused by a great or extreme amount of force applied over a period of time. The extent of a crushing injury may not immediately present itself.

A subconjunctival bleeding is typically a self-limiting condition that requires no treatment unless there is evidence of an eye infection or there has been significant eye trauma. Artificial tears may be applied four to six times a day if the eye feels dry or scratchy. [10] The elective use of aspirin is typically discouraged.
Bruise, which is a hematoma caused by trauma; Petechia, which is a small type of hematoma (<3 mm) Ecchymosis, which is a large type of hematoma (>1 cm) Purpura secondary to clotting disorders; Purpura hemorrhagica in horses; Pigmented purpuric dermatosis; Schamberg disease (progressive pigmentary purpura)
The treatment is the same as that for bruises in other parts of the body – cold compresses during the first twenty-four hours. During the process of healing, and so long as there no breaks in the skin, a black eye can be made less conspicuous by using cosmetics designed to obscure discolorations of the skin.
Patients may develop periorbital ecchymosis ("raccoon eyes"). [ citation needed ] Patients with subgaleal hematoma may present with hemorrhagic shock given the volume of blood that can be lost into the potential space between the skull periosteum and the scalp galea aponeurosis, which has been found to be as high as 20-40% of the neonatal blood ...
It refers to one of the three descriptive types of hematoma differentiated by size, the other two being ecchymosis (>1cm in diameter) and purpura (4 to 10mm in diameter). The term is typically used in the plural (petechiae), since a single petechia is seldom noticed or significant.
