Dermal nevi unspecified

Introduction

Pigmented nevi of indeterminate pigmentation, 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 neoplastic lesions. It is therefore important to know their characteristics and differences from other types of nevus.

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 to understand which lesions can be considered normal and which require further assessment.

Symptoms and diagnosis

Dermal nevus are characterised by a smooth surface and a skin-like or slightly brown colour. These lesions are usually small and can occur in various locations on the body.

How do you recognise dermal nevus?

The diagnosis of dermal nevus is often based on their clinical appearance. They are flat or slightly convex lesions with a regular shape and uniform colour.

Investigations and diagnostic tests

If in doubt, the 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 see a dermatologist?

It is advisable to consult a dermatologist if you notice a sudden change in the appearance of a mole, such as a change in colour, 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 a variety of causes, and its development is often linked to genetic and environmental factors.

Genetic factors and dermal nevus

Genetics play an important role in the development of pigmented nevi. Individuals with 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 not necessary unless the lesions cause discomfort or aesthetic inconvenience. Some people choose to have nevi removed 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 is carried out by a qualified specialist.

Is removal of nevi always necessary?

The 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 versus melanoma

Differentiating dermal nevus from melanoma is crucial, as melanoma is a malignant skin tumour that requires prompt intervention.

How do you differentiate dermal nevus from melanoma?

Dermal nevus are usually uniform in colour and shape, whereas melanomas may show irregularity and a variety of colours. If in doubt, consultation with a dermatologist is recommended.

The importance of regular skin examinations

Regular skin examinations are important to monitor any changes in existing nevi and to detect new ones. Early detection of melanoma significantly 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 monitor their children's skin changes regularly.

Changes in pigmented nevi with age

As people age, moles may change in appearance and some may even disappear. Regular dermatological examinations help to monitor these changes and take appropriate action if necessary.

Prevention and dermatological care

Proper skin care and regular visits to the dermatologist can help to keep the skin in good condition and detect potentially dangerous lesions early.

How to care for skin with pigmented nevi?

• Avoid overexposure to the sun and use sun protection.
• Monitor any changes in nevi and document them photographically.
• Consult your dermatologist if you notice any worrying changes.

The importance of regular visits to the dermatologist

Regular visits to the dermatologist are key to detecting lesions early and ensuring appropriate treatment. The dermatologist can assess the skin lesions and recommend appropriate management.

Summary

Pigmented nevi indeterminate, although usually benign, require regular monitoring. Early detection of lesions and appropriate diagnosis are key to preventing more serious health problems.

Key information about dermal nevus

• These are benign skin lesions commonly seen in dermatology practice.
• Regular monitoring and sun protection of the skin can help to manage them.

The importance of early diagnosis and treatment

Early diagnosis and treatment are important to prevent potential complications and ensure healthy skin for years to come.

FAQ

Frequently asked questions about pigmented nevi

Should every birthmark be removed?

Not every birthmark needs to be removed. The decision to remove should be made after consultation with a dermatologist.

How often should a birthmark be examined?

Regular visits to the dermatologist at least once a year are recommended, as well as self-monitoring of nevi at home.

Can dermal nevus develop into melanoma?

Dermal nevus rarely develop into melanoma, but regular monitoring is important for early detection of potentially dangerous lesions.
