Erysipelas

/ˌɛrɪˈsɪpɪləs/noun

A sharply bordered streptococcal infection of the upper skin, producing a raised, hot, scarlet patch.

The Greek roots

ἐρυθρός
erythrós
red
+
πέλλα
pélla
skin, hide

Literally: red skin

The story of the word

The second half of the compound is disputed: most link it to πέλλα, skin, though some read it as related to πέλλος, dark, which fits the colour less well. English called it St Anthony's fire through the Middle Ages, a name shared with ergot poisoning because both burned. The border of the rash is the diagnostic feature, raised enough that a doctor can feel where it stops.
