Additional information

Warts and blackheads are often considered synonymous, but are actually two distinct pathologies.

The distinction is to know the causes, the signs and the main characteristics, in order to establish the diagnosis and the appropriate treatment.


Warts are small benign lesions of the skin and mucous membranes caused by a virus, while blackheads (or comedones) are black or white spots resulting from clogged pores of the skin, especially by excess sebum, fat produced by the sebaceous glands. Blackheads are typical of acne, which affects about 80% of teenagers due to increased hormonal activity.


The warts result from a Human Papilloma Virus (HPV) infection. Injuries may appear months after contagion.

Blackheads form in the sebaceous follicle, where natural skin fat is produced. Fat accumulates in place and forms a blackhead.


Warts may appear in different areas of the body, but they mainly affect the soles of the feet (plantar warts), the fingers and nails (peri or subungual), the face and neck (threadlike). The genitals and perianal and anal region can also be affected (venereal warts or acuminate condyloma). But the blackheads preferentially manifest on the face and trunk, areas rich in sebaceous glands.


Warts appear as lumps, hard protuberances, and may have an irregular, rough or whitish or darker surface. Their size is variable and can be presented in isolation or in groups. Plantar warts can be confused with corns. The filiforms are long and thin. Venereal warts may look like a cauliflower.

Blackheads or comedones are small white or black dots. Blackheads are formed in larger open pores; whites appear in small, closed pores. They can give rise to infection by bacteria and lead to papules (pimples) and pustules (with pus).


Given that the causes are different, the treatment will also be different depending on whether we are dealing with warts or blackheads.

Warts - They can heal spontaneously without treatment, but they can also stay for years, disappear and reappear. The physician is responsible for assessing the case and proposing therapy, particularly for aesthetic or functional reasons. Treatments aim at the destruction of injuries by physical or chemical means and include:

Products with retinoic acid (a derivative of vitamin A), salicylic acid, among other peeling or keratolytic agents;

Surgical procedures (electrocoagulation, curettage);

Cryosurgery (cold therapy with liquid nitrogen).


Carnations - You will need to have a good deal of patience and follow some simple rules. Then just wait for the results. Until then, one should:

Cleanse the skin daily with appropriate solutions with non-comedogenic / comedolytic properties;

Avoid oily or greasy products that can clog the pores of the skin;

Do not squeeze;

Use specific products (retinoids, salicylic or azelaic acid), but on prescription due to side effects.


Attention! There is no point in always washing or rubbing black or white spots (these are the hardest to treat). This will only aggravate the problem, increasing the risk of irritation, infection and scarring.

Umbilical granuloma

Umbilical granuloma is described as a healing defect consisting of the formation of a sprout of granulation tissue that rises from the bottom of the umbilical scar; It is red in color, the appearance is moist and there is presence of serous or bloody discharge.

An accustomed health practitioner may prescribe silver nitrate in this situation.

However, some precautions should be observed when applying silver nitrate to the umbilical scar:

- guide the mother or caregiver / guardian about the procedure;

- gather necessary material, clean hands and put on gloves.

During application:

- observe granuloma appearance, presence of secretion or odor.

- For a better visualization of the region and to reduce the bacterial flora, pre-clean with a 70% alcohol-soaked pad from the base to the tip (outer part) towards the half moon, clean the surface of the surrounding skin with the second cotton swab and brush the rest of the stump with another cotton swab;

- if necessary, clean beforehand with soap and water;

- protect the skin of the peri-scar region with sweet almond oil or essential fatty acid solution to prevent chemical burn of nitrate on intact skin;

- place the silver nitrate stick on the granuloma for a few seconds until the color changes;

- Change region to complete the whole area of ​​the granuloma.

After application:

- Cover with gauze pad, without fixing, to protect the region from friction and put the diaper.

- guide the mother / caregiver / guardian to:

- continue hygiene in the umbilical scar with soap and water in the bath, removing secretions and scabs to reduce the bacterial population on the site;

- Keep the application with 70% alcohol after bath, leaving the place always dry;

- change diapers normally;

- Report to the healthcare professional any abnormalities in the region for evaluation of the healing process. In the presence of signs of inflammation around the navel, such as edema, hyperemia, and local heat with or without systemic signs of infection, omphalitis should be suspected. Refer for immediate medical consultation. In the absence of the cotton swab, a gauze pad can be used. Remind the mother that the procedure is painless to the child as there are no nerve endings in the granuloma. Therefore, if the child cries, it is not because of cleanliness.
