Introduction

Many people have moles, and most of them are completely harmless. But some moles look different, these are called atypical moles, and they can be sometimes mistaken for melanoma, a serious type of skin cancer.

While atypical moles are often not a sign of concern, it is important to understand what they are, how to spot warning signs, and when to call your doctor for medical advice.

 

What Are Atypical Moles?

An atypical mole is a mole that does not look like a normal mole with even brown spot. Experts sometimes call it a dysplastic nevus or dysplastic nevi.

These moles are not skin cancer, they may have some unusual characteristics like with a melanoma, which is why doctors keep a closer eye on them. It does not mean you will develop melanoma, but it means regular monitoring is important.

• B – Border: The edges look uneven
• C – Colour: There has more than one colour
• D – Diameter: The mole is larger than 6 mm
• E – Evolving: The changes in size, colour, shape or texture

• Itching or tenderness
• Bleeding without injury
• Scabbing or crusting
• Redness or swelling around the mole
