What is pustule?

What Does pustule Mean

The Latin word pustula gave rise to the term pustule , frequently used in the field of medicine . The word is used to name a swelling that occurs on the skin due to the accumulation of pus .

The pustules are part of what is known as primary efflorescence , which encompasses various alterations that occur in the epidermis . In this case, it is about holes in the skin that are filled with pus.
The appearance of a pustule can be due to various reasons. The most common is acne , a disease caused by the action of bacteria that infect the tissue. Pustules caused by acne usually appear during adolescence due to hormonal imbalances. Although these pustules do not cause major health problems and tend to disappear spontaneously with the passage of time, they can generate social problems and trauma to the adolescent who becomes self-conscious about skin lesions.

Malignant pustule
It is known as malignant pustule , anthrax or anthrax , on the other hand, a contagious disease. Its responsible is a bacterium called Bacillus anthracis that in most cases produces pustules, but which can also cause intestinal disorders and lung problems.
This disease is acute and serious and its objectives include all homeotherms (living beings that maintain their body temperature between two limits independent of ambient temperature), a group that includes human beings. Its consequences vary according to the mode of infection and the point at which treatment is started; their mortality rate is generally not high. When it attacks the lungs ( pulmonary anthrax ), on the other hand, it is usually fatal.
Treatment of a malignant pustule usually begins with high doses of antibiotics. When the infection occurs by inhalation, it is common for two types of antibiotics to be combined until certain advances are made and can continue, for example, with corticosteroids.
Folliculitis
Folliculitis is called the inflammation of one or more hair follicles, the parts of the skin in which hair can grow, thanks to its concentration of stem cells. This disorder can take place anywhere in the body and among its most frequent causes is the bacterium Staphylococcus aureus, also associated with boils and abscesses.

The onset of folliculitis usually occurs after the obstruction that occurs when shaving, the damage caused by friction with clothing, or hairstyles that are too tight and too close to the scalp.
Some of the symptoms of folliculitis are as follows:
* Pustules or pimples that surround the affected hair follicle, which usually appear in the groin or armpits and can generate scabs around it;
* itching of the skin;
* rash.
Regarding the treatment of this inflammation associated with the appearance of pustules on the skin, it is usually used: topical antibiotics, such as neomycin or mupirocin (it should be mentioned that if its indication is inappropriate, folliculitis can spread throughout almost the entire body ); topical antiseptic, which works in most cases; low-spectrum penicillins, such as flucloxacin (in the UK) and dicloxacillin (in North America).
Another meaning
Outside the orbit of medicine and dermatology, we speak of a pustule in reference to certain bumps that appear on seashells . These pustules are generated by the accumulation of calcite , a mineral whose chemical formula is CaCO3 . According to marine biologists, the pustules appear at the end of the calcification process.
