British spelling variant of amyxorrhea; a condition of reduced or absent mucus secretion.
The same Greek roots as amyxorrhea (a-, myxa, -rrhea), but spelled with the British '-rrhoea' ending instead of American '-rrhea.' Both forms are medically equivalent.
The amyxorrhea/amyxorrhoea spelling difference perfectly illustrates how medical terminology retained British spelling conventions even after American medicine diverged—these terms are frozen in time with their original Greek transliterations.
