'adenosarcoma' originates from Greek, specifically the words 'adeno-' meaning 'gland' and 'sarcoma' meaning 'fleshy tumor'.

'adenosarcoma' was formed by combining the Greek words 'adeno-' and 'sarcoma' to describe a tumor with both glandular and connective tissue components.

Initially, it meant 'a tumor with glandular and fleshy components', and this meaning has largely remained the same in modern usage.
