Relating to, resembling, or containing characteristics of fibromas or fibromatosis; composed of or affected by fibrous tissue tumors.
From fibroma + -ous (Latin, 'full of'). This descriptive adjective became standard in medical literature by the early 1900s for describing tissues or conditions related to fibromas.
When pathologists describe tissue as 'fibromatous,' they're saying it's essentially scar-like material gone rogue—your body's natural healing response misfired and kept going.
