Etymology: "Pyoderma" is a medical coinage built from two Greek elements: "pyo-", from Greek "pyon", meaning pus, and "-derma", from Greek "derma", meaning skin. Put together, the term describes a skin condition marked by pus, and it belongs to the modern scientific vocabulary of dermatology rather than to ancient medicine. Ancient Greek physicians had no such word, though they certainly described sores that oozed. The Greek roots themselves are old and familiar from other technical terms. "Derma" appears in words such as "epidermis" and "dermatology," while "pyon" shows up in "pyogenic," used for conditions that produce pus. Medical writers in the modern period routinely combined these classical building blocks to name newly distinguished diseases, which is why the word looks Greek without having been used by the Greeks.
