'adenocystomatous' originates from Greek, specifically the words 'adeno-' meaning 'gland', 'cysto-' meaning 'cyst', and '-matous' indicating a condition or state.

'adenocystomatous' was formed by combining Greek roots to describe a medical condition involving glandular cysts.

Initially, it meant 'related to glandular cysts', and this meaning has remained consistent in modern usage.
