Hematoma

/ˌhiːməˈtəʊmə/noun

A pocket of blood that has collected outside the vessels after an injury.

The Greek roots

αἷμα
haîma
blood
+
-ωμα
-ōma
swelling, growth

Literally: blood swelling

The story of the word

The Greek ending -ωμα only marked the result of an action, as in τραῦμα, a wound, or πτῶμα, something fallen. Nineteenth-century medicine narrowed it to swellings and tumours, which is why a hematoma sounds more sinister than the pooled blood of a hard tackle usually is. American spelling trims the ae of haematoma to a plain e, the same tidying that gives anemia and esophagus.
