A white dot on a mole

A mole, in most cases, is a benign neoplasm.

But if over time a person notices that a white dot has appeared on a mole, they should consult a doctor - a dermatologist.

Causes of a white dot on a mole

There are several reasons that can cause a white spot to appear on a mole:

1. Heredity.
2. Exposure to ultraviolet rays. This applies to both natural sources of ultraviolet radiation (sunbathing) and artificial ones: solariums, bactericidal lamps. Under their influence, the synthesis of melanin is activated, which is responsible for the formation of skin pigment, including pigment spots.
3. Radiation.
4. X-ray radiation dose.
5. Hormonal changes in the body: puberty, pregnancy, menopause or endocrine diseases.
6. Insect bite.
7. Acne or pimples.

Pathogenesis

To date, the pathogenesis of the appearance of a white dot on a mole has not been fully studied.

Symptoms of a white dot on a mole

Symptoms that should alert you and make you seek advice from a specialist:

1. A change in the shape of the mole is observed, the contours lose clarity and become blurred.
2. The mole loses symmetry.
3. A white dot appeared on the surface.
4. Pain may occur.
5. An increase in the size of the formation is possible.
6. The mole may itch and bleed.
7. The appearance of a new nevus with uneven coloring.

First signs

If a person is attentive to his health, then the first signs that should alert him are changes in the size and characteristics of a mole, the appearance of new moles that are not similar in their characteristics and color scheme to those already present.

White spots on a mole

If human skin is covered with moles, the number of which can change throughout life, both up and down, and they do not change, then there is no need to worry. But any change in shade, the appearance of white specks on a mole is a sign that should alert you and prompt you to take action!

Such a metamorphosis can be a banal pimple, or it can "speak" of the degeneration of a benign formation into a malignant tumor. For example, melanoma. You should not panic right away. Not all changes lead to cancer. But it is necessary to establish this fact and only an experienced and qualified specialist can do this.

Forms

World medicine has adopted a registry of diseases - "International Classification of Diseases, Tenth Revision" (ICD code 10). The appearance of a white dot on a mole can be attributed by doctors to melanoma nevi, marked with code D22.

Next comes the gradation depending on the location of the detection of the pathology:

• D22.0 – on the lips.
• D22.1 – on the eyelids.
• D22.2 – auricle, auditory canal and adjacent tissues.
• D22.3 – on unspecified areas of the face.
• D22.4 – neck and scalp.
• D22.5 – torso.
• D22.6 – shoulders and upper limbs.
• D22.7 – lower limbs and hip region.
• D22.9 – melanocytic nevus, unspecified.

Complications and consequences

If a person has noticed a change that has affected a nevus. Or he has found a recently appeared nevus with a visible white dot on the mole, the consequence of such development may be the process of malignancy.

But if such a mole has been observed for several years, there are other similar pigmented formations, or the person knows that the reason for the appearance of a white dot on the mole is an insect bite, then most likely there is no need to worry.

Complications

If you ignore the symptoms that appear, there is a high probability of developing complications - the degeneration of a benign neoplasm, which is a nevus, into a malignant tumor - melanoma. Melanoma is a cancerous neoplasm that develops as a result of malignancy of melanocyte cells, which are responsible for the synthesis of the pigment melanin in the human body.

Diagnostics of a white dot on a mole

Diagnosis of a white spot on a mole begins with a physical examination. The doctor carefully examines the neoplasm. An experienced doctor is already able to assess the nature of the changes at this stage of diagnosis. Then the specialist examines other moles present on the patient's body. After that, he is able to classify the nevus and with a high degree of probability assess the level of its potential danger in terms of malignancy.

Perhaps the doctor will calm the patient's fears and further diagnostics will not be required. The information received will allow not to miss the appearance of a truly dangerous neoplasm.

If there is a suspicion of a malignant nature of the change, the specialist prescribes laboratory and instrumental examinations for the patient. The doctor must find out the patient's heredity. Were there any patients with melanoma in his family?

Tests

A dermatologist or dermatologist-oncologist may prescribe the following tests:

1. Complete blood count.
2. Clinical urine analysis.
3. A blood test that detects cancer-specific markers such as lactate dehydrogenase (LDH) and S-100 protein.
4. Immunogram.

[ 9 ], [ 10 ]

Instrumental diagnostics

If there is a suspicion of a malignant nature of the changes occurring in the patient's mole, the specialist prescribes instrumental diagnostics. This may be one of the following methods or a set of diagnostic measures:

1. Molecular diagnostics. This method allows to recognize from a multitude of healthy cells the one that has undergone malignancy. The study of lymph node structures is carried out by reverse transcriptase polymerase chain reaction.
2. Dermatoscopy – makes it possible to use optics to detail the microstructure of a nevus and determine its nature.
3. After excision, if the mole is large enough and material for examination is obtained, the tissue must undergo histology and/or cytology. This examination method is called biopsy. It allows us to answer the question about the nature of the mole: whether it is a benign or malignant neoplasm.

Differential diagnosis

The attending physician differentiates the disease, the symptom of which is the appearance of a white dot on a mole, from other pathologies with similar symptoms.

1. Melanoma.
2. Insect bite.
3. Acne or pimples.

Treatment of a white dot on a mole

If the doctor has even the slightest suspicion of a malignant neoplasm or the beginning of the process of degeneration, the only way to treat it is to remove the mole with a white dot. But many people are interested in why one or another method of nevus excision is chosen to achieve the result?

Quite often, if the mole is large, doctors resort to classic excision of the formation using a surgical scalpel. The procedure is performed under local anesthesia (mostly lidocaine) and does not cause discomfort to the patient.

After the anesthesia takes effect, the surgeon makes an incision around the mole with a scalpel. The mole itself is removed with a white dot and a small area of tissue around it. The wound is sutured and a sterile bandage is applied.

As a result of the operation, the patient gets rid of the problem, and the specialist receives a tissue sample for examination. Such tissues are sent for histology, which draws a conclusion about the nature of the cells being examined. If changes are detected that affect the cells of the sample being examined, the patient can be sent for a more extensive examination to a specialized oncology clinic.

Malignization of a mole occurs in limited cases. Therefore, if there are no prerequisites to "suspect" the cells of the neoplasm of malignancy, and the nevus is small in size, the dermatologist may resort to another method of removing a mole with a white dot.

There are several such methods today:

1. Laser cauterization.
2. Cryocauterization (freezing) – removal of neoplasm with liquid nitrogen.
3. Electrocoagulation is burning using electric current discharges.
4. Radio wave surgery.

People wishing to get rid of a nevus should be warned that this procedure should never be performed at home or in a beauty salon. Such surgical treatment at a high professional level can only be performed in a specialized medical institution.

If there is a risk of malignancy, removal of a mole with a white dot is mandatory and is performed only surgically! The use of laser therapy, cryo- and electrocautery in this case is unacceptable.

Medicines

On the shelves of modern pharmacies you can find medicines (as noted in their instructions) that allow you to easily remove nevi at home. Doctors are sounding the alarm and warning that any self-medication is unacceptable.

If after surgical removal of a mole the patient feels pain in the area of the operation, the attending physician prescribes a painkiller. This may be cefekon D, ifimol, febricet, acetaminophen, tylenol, perfalgan and a number of others.

Paracetamol is prescribed to patients over 12 years of age. It is recommended to take the drug one to two hours after eating. Dose: 0.5 to 1 g with plenty of water. If necessary, the painkiller can be taken at intervals of 4 to 6 hours.

The dosage should not exceed 4 g per day.

If the patient has a history of kidney and/or liver dysfunction, Gilbert's syndrome, the prescribed dosage of the drug should be reduced, and the interval between doses, on the contrary, increased.

Depending on the age and weight of the child, the recommended dose changes:

1. For a patient aged three to six years, weighing 15–22 kg – daily dose 1 g.
2. From six to nine years old, weight 22 – 30 kg – recommended daily amount 1.5 g.
3. From 9 to 12 years old, weight up to 40 kg - daily dosage 2 g.

The interval between doses should be at least four hours.

Contraindications to the administration of paracetamol include individual intolerance of the patient's body to paracetamol or another substance included in the drug, severe renal and/or liver dysfunction, as well as the child's age under three years.

Folk remedies

If the cause of the white spot on the mole is a pimple (acne), such a clinic is not dangerous. It should not be squeezed. A few days are enough and the situation will resolve itself, the channel will be cleared. In such a situation, folk remedies can help eliminate such a symptom as itching.

If there is a suspicion of malignancy of a mole, no folk treatment is applicable.

Herbal treatment

We can offer several recipes that will reduce the intensity of itching in the area of a pimple localized in a mole; direct treatment of a white spot on a mole with herbs is not carried out.

1. Lotions from the infusion of the succession. It can be prepared by pouring two tablespoons of the plant with half a liter of boiling water. 40 minutes is enough for the solution to brew and be ready for use. With a swab soaked in the medicine, gently wipe the mole with a white dot. Perfectly relieves itching.
2. An effective tincture is prepared based on the medicinal plant oregano. The liquid is prepared by infusing a tablespoon of the plant in a liter of boiling water. After infusing, strain the composition and use it to treat the skin.
3. Burdock root can also help alleviate the condition. Add a tablespoon of crushed raw material to half a liter of boiling water. Boil for half an hour on low heat. It is advisable to apply the compress to the sore spot overnight.

Prevention

To prevent the development of melanoma, doctors provide a number of recommendations, the implementation of which will protect the body from the degeneration of a nevus into a malignant neoplasm or will make it possible to recognize the pathology at an early stage of its origin. Prevention of the occurrence of a white dot on a mole includes several points:

1. Avoid excessive tanning and prolonged exposure to direct sunlight.

1. Eliminate or minimize visiting a solarium. Especially if a person has a hereditary predisposition to this disease.
2. Conduct regular examination of your body for changes in the shade or shape of existing moles, and also record the appearance of new ones. If necessary, seek advice from a qualified doctor - dermatologist or dermatologist - oncologist as soon as possible.
3. If a person's body is covered with numerous nevi, it is possible to take baths using a soft washcloth.
4. Make sure that the mole is not injured.
5. It would be a good idea to undergo regular preventive examinations with a dermatologist.

Forecast

The prognosis of a white spot on a mole largely depends on the reason for its appearance. If it is a banal pimple, then there is nothing to worry about. With melanomas, the probability of progression of the pathological process is quite high, but timely removal of the mole usually leads to a favorable outcome.

Self-medication if a white dot appears on a mole is absolutely unacceptable. The first thing a person should do is to consult a specialist who will differentiate the mole, make the correct diagnosis and, if necessary, prescribe adequate treatment.
