What does it mean when a mole that was removed shows severe atypia?

Severe atypia in a removed mole, also known as atypical hyperplasia or dysplasia, indicates the presence of abnormal changes in the cells of the mole that may raise the risk of developing skin cancer. Severe atypia is considered a more concerning finding compared to mild or moderate atypia.

Here's what severe atypia means:

1. Cellular Abnormalities: Severe atypia refers to significant deviations from the normal appearance of cells within the mole. These cellular changes may involve alterations in cell size, shape, and organization.

2. Increased Risk of Skin Cancer: Moles with severe atypia are considered atypical nevi and have a higher chance of developing into melanoma, a serious form of skin cancer, compared to typical nevi (common moles). However, it's important to note that not all atypical nevi will necessarily become cancerous.

3. Need for Close Monitoring: Dermatologists recommend close monitoring of moles with severe atypia. This involves regular follow-up examinations and monitoring for any changes in size, shape, color, or elevation of the mole.

4. Treatment Options: In some cases, a dermatologist may recommend removing atypical nevi with severe atypia to reduce the risk of potential skin cancer development. The removal is usually done through surgical excision or other appropriate methods to ensure complete removal.

5. Avoidance of Sun Exposure: Individuals with moles exhibiting severe atypia are advised to minimize excessive sun exposure and protect their skin by using sunscreen, wearing protective clothing, and avoiding peak sunlight hours.

6. Importance of Self-Examination: Regular self-examination of the skin, including moles, is essential for early detection of any changes or new abnormal lesions. If any concerning changes are observed, it's advisable to consult a dermatologist promptly.

It's crucial to seek the advice of a dermatologist for evaluation of any mole showing severe atypia. They will assess the specific characteristics of the mole, determine the appropriate course of action, and provide guidance for ongoing monitoring or treatment if necessary.
