A fleshy or abnormal growth or swelling, especially within the body; the state of being fleshy.
From Latin 'carnosus' (fleshy) plus the suffix '-ity'. Historically used in medical contexts to describe unexplained fleshy growths.
This is an archaic medical term that's mostly vanished from modern practice—we now have specific names for growths. But it survived for centuries because doctors needed a general term for 'weird fleshy thing that shouldn't be here!'
