Etymology: "Leiomyomas" is the plural of "leiomyoma," a medical term built entirely from Greek parts and first formed in modern scientific writing rather than in antiquity. The first element, "leio-," comes from Greek "leios," meaning smooth, while "myoma" combines "mys," muscle, with the suffix "-oma," used in Greek and later medical Latin for swellings and growths. Put together, the name describes exactly what the tumor is: a growth made of smooth muscle tissue. The "-oma" ending is the same one found in words like "carcinoma" and "lymphoma," which lets a reader spot a tumour's category from its name alone. The "myo-" part marks the tissue, and "leio-" marks the particular kind of muscle, distinguishing it from the striated muscle that moves the skeleton. Because the word is a technical coinage, no ancient writer ever used it; the Greek pieces were simply assembled by doctors who needed a precise label.
