Etymology: "Desquamations" is the plural of "desquamation," a medical term for the shedding of skin in flakes or layers. The noun traces back to the Latin verb "desquamare," meaning to scrape the scales off a fish, built from the prefix "de-" (off) and "squama," meaning scale. The image is a literal one: a fish being cleaned of its scales. Latin "squama" was used for the scales of fish and reptiles, and by extension for anything arranged in overlapping layers. The same root gives English words such as "squamous," used of flat, scale-like cells, and "squame," a scale or thin flake of skin. Physicians applied the Latin image to human skin, which sheds in thin layers much as a fish's scales loosen and come away.
