Does Melanoma Always Appear as an Atypical Mole?

You may think melanoma always looks like a dark, irregular mole with a suspicious look. While that image can certainly describe some melanomas, the truth is more complex. Melanoma, the most deadly form of skin cancer, doesn’t always appear as an atypical mole.

At Limmer Dermatology in San Antonio, Texas, we want to make sure you understand the facts and myths of melanoma so you can stay informed and proactive about your skin health.

Melanoma is more than just a "bad mole"

Melanoma is a type of skin cancer that originates in the pigment-producing cells in your skin called melanocytes. While it’s the least common of the major skin cancers, it’s the most dangerous due to its ability to spread rapidly to other parts of the body.

Many people with melanoma assume that their moles don’t look “weird.” They believe they’re safe, but that’s not always the case.

Melanoma can look like a normal mole

Melanoma can sometimes resemble a regular mole or even develop in skin that looks completely normal. In some cases, melanoma appears as:

• A small, evenly colored spot that looks similar to a benign mole
• A pink, red, or skin-colored bump
• A lesion that looks like a pimple or scar
• A streak under a fingernail or toenail

Melanoma can also appear as a slowly growing patch of discoloration, especially on sun-damaged skin.

The differences in how melanoma can appear are why routine skin checks, both at home and in our office, are so essential.

The ABCDE rule

The ABCDE rule is a helpful tool to evaluate moles and spots on the skin. ABCDE teaches you to look for moles with:

• Asymmetry
• Border irregularity
• Color variation
• Diameter larger than 6mm
• Evolving over time

Although these indications can be helpful, not all melanomas follow these rules. Some cases fall outside these classic signs, especially in their early stages. This means even "normal-looking" spots should be evaluated if they appear new, change subtly, or just don’t feel right.

If you’re in doubt, schedule an appointment

One of the most powerful tools in catching melanoma early is your intuition. If you notice a new spot or a mole that seems "off," even if it doesn’t look concerning by textbook standards, it’s worth having it evaluated by a board-certified dermatologist at Limmer Dermatology.

At our office, we encourage patients to come in for annual skin checks and sooner if something suspicious arises. With early detection, melanoma has a very high cure rate.

Melanoma doesn’t always announce itself with an obvious warning sign. While atypical moles can certainly be a red flag, it’s important to know that this isn’t the only way melanoma presents itself.
