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

'adenosarcoma' was derived from the combination of 'adeno-' and 'sarcoma' in medical terminology to describe tumors 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.
