exostoses

Noun

exostosis (countable and uncountable, plural exostoses)

1. A benign, bony growth, often covered with cartilage, on the surface of a bone or tooth.
   • Unquestionably, gentlemen, the bones most liable to exostosis are, first, the femur; secondly, the humeri; and thirdly, the lower jaw. But exostoses are met with on the sternum clavicle, and the bones of the head; in short, I may state, that there are no bones on which exostoses may not be produced.1834, Samuel Cooper, “Lectures on the Principles, Practice, & Operations of Surgery: Lecture LXIV”, in Michael Ryan, editor, The London Medical and Surgical Journal, volume 4, Henry Renshaw, page 516
