An alternative British spelling of dermatorrhea, referring to abnormal discharge or flow from the skin.
From Greek 'derma' (skin) + 'rhoea' (flow, British spelling variant), equivalent to American dermatorrhea.
This is simply the British English spelling preference for the Greek suffix '-rhoea' instead of '-rhea'—the same distinction that makes 'diarrhoea' versus 'diarrhea' look like different words.
