What does desquamated mean?
Desquamated is the past tense and past participle of the verb "desquamate," meaning to shed or come away in scales or fine flakes. The word belongs almost entirely to the vocabulary of medicine and biology: pathologists examine desquamated cells, dermatologists describe how sunburned or diseased skin has desquamated, and histologists study desquamated epithelium. It derives from the Latin squama, meaning "scale," the same root that gives us "squamous" (as in squamous cell carcinoma), which makes its sense easy to anchor — anything desquamated has come off the body the way a snake's skin comes off in scales. Although precise and useful within clinical writing, it is decidedly formal and technical; in ordinary speech, people say skin peeled, flaked, or sloughed off rather than desquamated. Its rarity outside specialist contexts gives it an authoritative, scientific flavor whenever it does appear.

Etymology of desquamated
Desquamated comes from the Latin verb desquamare, formed from de- ("away from") plus squama ("scale"), so it literally means to strip away scales. English adopted the related forms "desquamate" and "desquamation" around the early nineteenth century as medical terminology. It shares its Latin root with "squamous" and other anatomical terms built on squama, all relating to scale-like structures.

How desquamated is actually used
Strictly clinical and technical in register — used almost exclusively in medicine, dermatology, pathology, and histology. Rarely heard in everyday conversation, where speakers would say "peeled" or "flaked" instead.
Easily confused with desquamated
"Desiccated" means dried out completely, while "desquamated" refers to shedding in flakes or scales; the two share a similar opening but describe entirely different processes.
