A type of tumor containing both fibrous tissue and sand-like mineral particles called psammoma bodies.
From fibro- + psammoma (Greek psammos, sand + -oma, tumor). This medical term specifically describes a rare tumor where calcium deposits create a gritty appearance.
When pathologists look under a microscope at these tumors, they literally see what looks like sand grains scattered throughout—it's like your body's cells are creating their own tiny beaches, and these 'psammoma bodies' are actually important diagnostic clues for doctors.
