'adamantinoma' originates from Greek, specifically the word 'adamantinos,' where 'adamant-' meant 'unbreakable' and '-oma' is a suffix used in pathology to denote tumors.

'adamantinos' transformed into the medical term 'adamantinoma' to describe a specific type of tumor.

Initially, it referred to something 'unbreakable,' but over time it evolved into its current meaning of a specific type of tumor.
