Pigmented nevi unspecified (Dermal Nevus)
Introduction
Pigmented nevi of indeterminate color, also known as dermal nevus, are benign skin lesions that arise from the accumulation of melanocytes in the dermis. Although they are common, their importance in dermatology cannot be overestimated, as they can sometimes resemble cancerous lesions. Therefore, it is important to know their characteristics and differences from other types of nevi.
Importance of dermal nevus in dermatology
Dermatologists often encounter dermal nevus in their practice, which requires them to have a thorough knowledge of these lesions. Understanding how dermal nevus may differ from other nevi is crucial for effective diagnosis and management. This knowledge also helps patients understand which lesions can be considered normal and which need further evaluation.
Symptoms and diagnosis
Dermal nevus are characterized by a smooth surface and a skin-like or slightly brown color. These lesions are usually small and can occur in various locations on the body.
How to recognize dermal nevus?
The diagnosis of dermal nevus is often based on their clinical appearance. These lesions are flat or slightly convex, regular in shape and uniform in color.
Examinations and diagnostic tests
When in doubt, a dermatologist may choose to perform a dermatoscopy, which allows a closer look at the structure of the nevus. In some cases, especially if the lesion is atypical, a biopsy may be necessary.
When to visit a dermatologist?
It is advisable to consult a dermatologist if you notice a sudden change in the appearance of a nevus, such as a change in color, shape or size. It's also worth going for a routine check-up if you have multiple nevi on your body.
Causes and risk factors
Dermal nevus can have various causes, and its development is often linked to genetic and environmental factors.
Genetic factors and dermal nevus
Genetics plays an important role in the development of pigmented nevi. Individuals who have a family history of multiple nevi may be at higher risk of developing them.
Environmental influences on the development of pigmented nevi
Exposure to UV radiation, especially at a young age, can increase the risk of developing dermal nevus. It is important to protect the skin from the sun by using appropriate sunscreens and avoid overexposure to the sun during peak sunlight hours.
Treatment and removal
Treatment of dermal nevus is usually unnecessary unless the lesions cause discomfort or aesthetic inconvenience. Some people choose to remove nevi for cosmetic reasons.
Treatment methods for dermal nevus
The most common method of nevus removal is surgical excision, which guarantees complete removal of the lesion and allows histopathological examination of the specimen.
Safe nevus removal techniques
Other removal methods include cryotherapy, electrocoagulation and laser therapy. It is important that each procedure be performed by a qualified specialist.
Is nevus removal always necessary?
Removal of nevi is not always necessary. The decision to remove should be made after consultation with a dermatologist, depending on the individual needs of the patient and the characteristics of the nevus.
Dermal nevus vs. melanoma
Differentiating dermal nevus from melanoma is crucial, as melanoma is a malignant skin tumor that requires prompt intervention.
How do you differentiate dermal nevus from melanoma?
Dermal nevus are usually uniform in color and shape, while melanomas may show irregularity and a variety of colors. If in doubt, it is advisable to consult a dermatologist.
Importance of regular skin examinations
Regular skin examinations are important to monitor any changes in existing nevi and detect new ones. Early detection of melanoma greatly increases the chances of successful treatment.
Dermal nevus in children and adults
Dermal nevi can occur in both children and adults, and their development and changes with age may differ between the two groups.
Development of pigmented nevi in children
In children, nevi can appear at a young age and often change as they grow up. It is important for parents to regularly monitor their children's skin changes.
Changes in pigmented nevi with age
As people age, moles can change their appearance and some may even disappear. Regular dermatological examinations help monitor these changes and take appropriate action if necessary.
Prevention and dermatological care
Proper skin care and regular visits to a dermatologist can help keep skin in good condition and detect potentially dangerous lesions early.
How to take care of skin with pigmented nevi?
- Avoid overexposure to the sun and use sunscreen.
- Monitor any changes in nevi and document them photographically.
- Consult a dermatologist if you notice any worrisome changes.
The importance of regular visits to a dermatologist
Regular visits to a dermatologist are key to detecting lesions early and ensuring appropriate treatment. A dermatologist can evaluate skin lesions and recommend appropriate treatment.
Summary
Nonspecific pigmented nevi, although usually benign, require regular monitoring. Early detection of lesions and appropriate diagnosis are key to preventing more serious health problems.
