Definitions

Etymology: "Keratomas" is the plural of "keratoma," a medical term for a thickened patch of skin. The word is a modern scientific coinage built from two Greek elements: "keras," meaning "horn," and the suffix "-oma," used in medicine for a growth or swelling. Its base, "keratin," shares the same "horn" root, which is why these lesions are named for the hard, horny texture they produce. Some medical writers also use the Greek-style plural "keratomata."
