In fact, for skin cancer screening, we are told to check our ABCD’s, and the “C” stands for color: If a mole changes color, not only is this suspicious and should be examined by a doctor, but melanoma can cause a mole to “turn red.”
The year prior I had drawn a mole map of my lower leg so that I could then know what has apparently always been there, as far as moles.
But I never referred back to the map until a year later. And that’s when I discovered a little dark brown spot that was not on the mole map!
It was on my shin, nearby a prominent mole, so how could I have possibly missed it when I was drawing the map?
The only explanation: It was a new mole! Normally, moles do not appear in people over 30, though new moles can appear throughout life. However, dermatologists are leery about new moles later in life.
In fact, according to dermatology Web sites such as lagunaskincenter.com/articles/moles/, new moles are common in people up to age 30. But past 30, these are to be regarded as suspicious and should be examined by a doctor.
Because I thought the spot on my shin was new, I scheduled an appointment with a doctor. She said it looked benign and I decided to just “watch” it.
I had already lined up an appointment with her prior anyways, which was two months away, for my annual routine skin exam. I looked at this new spot three times per week for a while, then once every three days.
On a Thursday, it appeared as it always had since I discovered it: a 1-millimeter brown mole. On Sunday, about 48 days after the doctor had examined it, it appeared a fraction larger, and had a red tinge to it.
I knew I wasn’t imagining the vague increase in size because all along, I had been measuring it up against a file card on which I had drawn two spots with a pencil: one the same size as the mole, and one just a fraction larger.
On Sunday, with the index card against my leg for a side-by-side comparison, I saw that the speck was a hair bigger than the spot that it was supposed to be the same size as, and the SAME size as the penciled spot that it was supposed to be a fraction smaller than!
Now, you might be thinking I’m a hypochondriac, but just weeks before, I had a rapidly changing mole removed from my back! So I was still uptight. The changing mole on my back turned out to be benign.
I was also positive I was not imagining that the spot on my leg had a new reddish tinge to it. I had other small spots just like this one on my leg, all the same shade of brown, and when I compared this particular spot to the others, I could clearly see that it just didn’t match anymore in color.
On Monday I made an appointment to have it removed for the following Friday. So, for five days, I suspected melanoma. Why ELSE would this mole have developed the reddish cast and gotten a tiny bit larger?
You read about how a changing mole can mean melanoma, and how when it changes colors (remember that “C”?) it can mean melanoma, and how the color red can mean melanoma in a previously brown or tan mole.
Over the next five days the mole reverted back to its original size, which provided me relief, but it remained reddish brown, though I was positive that come Friday morning, it was less red and more brown; closer to its original brown, but still tinged reddish.
Though the doctor (dermatologist) informed me that the mole was the same size as it was about 53 days prior, when she had first examined it, she then alarmed me by stating, “It looks red.”
So now I knew for sure I wasn’t imagining that the brown mole had turned a bit red. She removed it with a “shave” procedure, taking with it a small margin of surrounding skin.
When the nurse called with the biopsy results, she said: “It’s a lentigo simplex. That means it’s benign.” She added, “A benign sun spot.”
So what had turned this brown “mole” red? The nurse said that “simplex” is a term used to describe something that had been irritated from being scratched or rubbed.
I had no recollection of scratching or rubbing this area, but then again, it’s not impossible to be unaware of reaching down to scratch one’s leg. It can happen in your sleep.
Nevertheless, the pathology report does not lie: a lentigo simplex.
A lentigo is not a mole, even though the terms are often used interchangeably. A lentigo can look just like a mole, however.
And because I had thought the spot was a mole, I referred to it as a “mole” throughout this article. But a lentigo can look just like a mole (nevus), and a lentigo can also turn into melanoma, said my doctor.
In conclusion, a brown “mole” that changes to red isn’t always melanoma, but if you notice a brown “mole” turning reddish or red, see a dermatologist, because only a biopsy can rule out melanoma. Melanoma kills around 9,500 Americans yearly.
