In-Situ (In place) Melanoma is also known as Stage 0 Melanoma and Hutchinson’s melanotic freckle. The latter is in honor of Sir John Hutchinson, who provided its inaugural description in the late 19th century.
While our fervent goal is to continually help prevent people from developing melanoma, if you are diagnosed with it, this is the type you’d prefer. As with burns (1st, 2nd, 3rd degree) and golf scores, with melanoma the lower number you have the better.
What are In-Situ Melanomas?
In-Situ are radial melanomas that stay within the skin’s thin top layer. Unlike their far more dangerous cousins, they don’t penetrate the epidermis and spread throughout the body. They don’t move. Hence, in place.
They’re also very easy to see, and have nearly a 100% cure rate. Typically, a doctor simply removes them right in his or her office. And that’s that.
These are two examples of In-Situ Melanomas:
Lentigo Maligna and Lentigo Maligna Melanoma
Lentigo Maligna is a very slow-growing (up to 20 years) In-Situ melanoma. It develops most often in older people, and within those whose vocations require a significant amount of time spent outdoors. As its primary cause is sun exposure, “Lentigos” usually occur on the areas of skin that are most prone to be impacted by the sun’s harmful UV rays. These include- but are certainly not limited to -the hands, neck and face.
Of all the In-Situ varieties, Lentigo Maligna is the least likely to convert to an aggressive, potentially lethal skin cancer. If it does however, it becomes Lentigo Maligna Melanoma. If Lentigos are allowed to reach this invasive melanoma stage, the matter grows much more serious.
Unlike the aforementioned Lentigo Maligna, Lentigo Maligna Melanoma is not a simple out-patient procedure. It requires surgery during which the surgeon will remove the affected skin entirely; along with a portion of the healthy skin that surrounds it. How it’s treated is based on what the case’s pathologist determines.

While we may sound like a broken record at times, these, along with so many other skin cancer and sun skin damage issues, can be avoided merely by practicing sun-safety and monthly self-examination. Please, do it for your own sake; and for the sake of those who care about you.

Self-examination is among the most vital weapons we all have in the fight against melanoma. There is no doubt that the more people the melanoma awareness community can reach with this message, the more lives it can save.
Why is Self-examination So Important?
As that is a fair question, we’ll give you two excellent reasons. The speed at which melanoma is discovered and treated is literally the difference between life and death. If diagnosed early enough, it can be cured quite easily. If too late, it can (and will) spread throughout the body and then painfully attack our other organs until it turns fatal.
Another fact is that patients first discover their melanomas more often than their doctors will. And of course, many of us don’t visit our physicians regularly enough to depend on them to sufficiently monitor our skin.
A Few Notes About Self-examination
The good news is that self-examination is a simple process, and takes only ten minutes or so per month. For those who may need extra motivation, please note that almost every melanoma fatality could have been prevented by early self-detection.
Furthermore, around 30% of melanomas develop onto areas of our skin that are rarely, if ever, introduced to the sun. So even if you do see your doctor on a schedule, he or she likely wouldn’t examine you in some of those areas anyway. Unless you bring it to their attention.
Performing Your Self-examination
There are two main forms of melanoma: Radial and Nodular. Nodular is the less common of the two, but it’s also deadlier. And though rare, our percentage chances of developing it are much higher in our adolescence and teenage years than they are after we reach adulthood. To learn much more about nodular melanoma, please click here.
This is how you search for radials:
On the parts of your skin that you can easily see, (arms, front/sides of legs, between fingers, toes, palms, soles, under finger and toenails) check for any new or existing moles, blemishes and marks with irregular shapes and/or dark colors. Also, note any that turn itchy and/or begin secreting fluids.
Use the combination of a full-length mirror and a hand mirror to check your back, back of legs, ears, armpits, neck and private areas. Employ a hairdryer to move your hair around as you check over your scalp.
Here are a couple of tips to make it even easier than that:
If you have a spouse, significant other or trusted friend, ask him or her to check your back and ears.
Many of us get our hair styled or cut every month or two. If this includes you, excellent. Simply ask your barber or stylist to alert you if he or she comes across any odd marks while performing their task.
For an easy access to this process, just save and print out this diagram:
Gender, Ethnicity and Melanoma
While it’s true that Caucasians and other pale-toned ethnicities are more likely to develop melanoma, it’s equally true that anyone of any age, gender or skin color can develop it, too. In fact, though it’s certainly more common in white people, once it appears it’s more often fatal to African-Americans.
Melanoma can begin anywhere on our bodies. If you’re a Caucasian man or woman, this diagram will show you the percentage breakdown of where it occurs:
If you’re Asian, Hispanic or African-American, it can be most commonly found on your hands, feet, toe and fingernails, and between the toes and fingers themselves. Indeed, legendary singer Bob Marley’s ultimately fatal Melanoma began in his toe.
Self-examining for Early Signs of Melanoma
Please, take just a few minutes out of each month to protect your health.
Welcome to the Melanoma Education Foundation’s (MEF) inaugural blog post. In the weeks to come, we’ll be bringing you updates and information relevant to our foundation’s goals; as well as other news that is specific to Melanoma and skin cancer awareness.
With this initial post, however, we’d like to tell you a little about ourselves, our goals, and what to expect going forward. This is so that we may acquaint ourselves with those who are learning about us for the first time through this blog.
Our nonprofit organization was founded by Steve Fine in 1999, the year after his son Daniel tragically succumbed to Melanoma at only 26 years old.
Steve has since never wavered in his ambition to spare adolescents and teenagers from Melanoma; the worst form of skin cancer. If not caught in time, the disease is often fatal. However, if discovered in its earliest stages it can be easily cured. With Melanoma, the time it takes to detect and treat is everything; and is usually the difference between life and death.
From its beginnings, MEF learned that many health educators didn’t realize the vital importance of including information about Melanoma within their curricula. For MEF, the idea is to help teachers inform their students how to find Melanoma quickly, along with the best ways to avoid it entirely.
MEF’s goals are prominently listed on our website, skincheck.org. They are as follows:
- Educate middle and high school health teachers and provides them with free online classroom lessons for their students.
- Provide complete information about early self-detection and prevention of Melanoma in a user-friendly website.
MEF’s popular The Melanoma Lessons are now taught in more than 1,700 schools all over the United States. The single-period lessons focus on early self-detection prevention of melanoma for middle and high school students. They are easy for educators to learn and easy to teach. *
With further regard to our websites; skincheck.org is a comprehensive, powerful, yet easy-to-navigate educational tool for anyone and everyone. While very similar in content, melanomaeducation.net additionally provides health educators with access to student teacher videos and lesson plans.
Both websites are packed with information about Melanoma. Included within them are its causes, prevention techniques, warning signs, statistics, how to check yourself, and much more. You’ll also find numerous relevant photographs and videos.
This blog will serve as an adjunct to our website, and focus more on singular issues each week. The basic facts about Melanoma remain relatively stationary. However, the wheels of medical science are always in motion. As we’ve all seen over the past couple of decades, they’re moving faster now than ever before. And they will move faster still. Using the massive power of social media, our posts will allow us to deliver the news of whatever breakthroughs, upgrades, or even setbacks are on the horizon, to a much larger audience.
We not only welcome you to, but encourage you to share these posts. Our only desire is to see Melanoma swept away forever into the dustbin of history. With your help, there’s no doubt that someday that day will arrive.
Thank you.Introducing the Melanoma Education Foundation’s New Blog
