A gumma (plural gummata or gummas) is a soft, non-cancerous growth resulting from the tertiary stage of syphilis (and yaws).

It is a form of granuloma. Gummas are most commonly found in the liver (gumma hepatis), but can also be found in brain, heart, skin, bone, testis, and other tissues, leading to a variety of potential problems including neurological disorders or heart valve disease.
