'adenomyxoma' originates from Greek, specifically the words 'adeno-' meaning 'gland' and 'myxoma' meaning 'mucous tumor'.

'adenomyxoma' was formed by combining the Greek words 'adeno-' and 'myxoma' to describe a tumor with both glandular and mucous components.

Initially, it meant 'a tumor with glandular and mucous components', and this meaning has remained consistent in modern medical terminology.
