'angiomyosarcoma' originates from modern medical Latin, specifically the combination of 'angio-' meaning 'vessel', 'myo-' meaning 'muscle', and 'sarcoma' meaning 'fleshy tumor'.

'angiomyosarcoma' was formed in modern medical terminology by combining Greek-derived roots to describe a tumor with blood vessel, muscle, and connective tissue components.

Initially, it meant 'a tumor with blood vessel, muscle, and connective tissue elements', and this meaning has remained unchanged in modern medical usage.
