What does pustulation mean?
Pustulation is a formal medical term for the formation or presence of pustules, the small, pus-filled blisters that can develop in certain inflammatory skin disorders. In clinical writing, it can refer either to the underlying process or to the resulting eruption, especially when numerous lesions appear across the skin. A sentence such as “The patient developed widespread pustulation” therefore describes both the appearance of the lesions and, by implication, the pathological process behind them. The word is uncommon outside medical and dermatological contexts and sounds considerably more technical than the everyday phrases “pus-filled blisters” or “a pustular rash.” Its usefulness lies in identifying a specific clinical pattern associated with pus-filled lesions, which may occur in reactions to medicines as well as in other skin diseases. The related terms pustule and pustular are common in specialist descriptions, while pustulation is chiefly reserved for naming the process or a conspicuous, often widespread, eruption.
nounThe formation or presence of pustules, especially on the skin; also, an eruption of pus-filled blisters.
- The formation of one or more pustules on the skin.

"The rash evolved into severe pustulation across the patient's torso."
"The patient developed widespread pustulation following a new medication."
"Warm compresses were applied while the pustulation subsided."
The plural is grammatically possible but uncommon; singular or mass-noun usage is more typical.
"The notes distinguished recurrent pustulations from a single persistent eruption."
Pustulation is the medical name for the formation of pus-filled blisters, whether it affects one small patch or covers a large area of skin.

Where does pustulation come from?
Pustulation was formed in English from pustule plus the suffix -ation, expressing formation or action. Pustule comes through French from Latin pustula, a term for a pustule or blister; the same Latin root underlies pustular, pustulous, and pustulate. The English word follows a productive pattern in which adding -ation to a related noun creates a name for a process.
How pustulation is actually used
Chiefly used in medical and dermatological contexts. It is uncommon in general conversation and may refer either to the pathological process or to the resulting eruption.
