Hematoma

Hematoma is an abnormal collection of blood outside of the vascular space, e.g. blood vessels. The clinical significance is dependent on the size, location and co-morbidities. They are important to document in the context of forensic pathology. Hematomas are usually described by location and size.

Hematoma should not be confused with hemangiomas, a type of vascular tumour, or post-mortem extravascular blood collections.
