Even after the End of Heat season has passed, the heat wave still continues.
Since opening Korea’s first specialized hospital for nail treatment in 1995, I have focused on only one field for 25 years. We treat all nail and toenail conditions.
Toenail fungus is completely cured in the shortest period in Korea, about 4 months, using a pinpoint laser.
A minimum treatment period of 4 months is a feature unique to my hospital.
Ingrown toenails are simply treated with a device that straightens the nail without surgery (commonly called a corrective device).
If corrective-device treatment is not possible,
surgical treatment is used to provide a simple, permanent effect.
Nail melanonychia occurs from melanocytes.
Because a certain percentage can be malignant,
it is standard to distinguish them through a biopsy.
Thanks to advances in testing methods, at our hospital the test takes about 5 minutes, with almost no pain or wound.
If readers have any questions, send me a photo and a message, and I will answer (question phone: 010-9682-1501).
And after making a reservation, you can visit (02-3431-1500).
(This is Naeil Clinic on the 4th floor of City Pharmacy, 100 meters ahead of Exit 4 of Jamsilsaenae Station on Line 2.
It is by reservation only.
Thursdays are closed.)
The black color is very strong.
How does it look to you?
Take a guess.
...................................
This is the most common question.
It is a bruise at the nail root, that is, in the lunula area. This is also a photo that raises many questions, but it is a little different.
It has an unclear border and a bleeding color,
and it will disappear. However,
the photo above has a tail. This means that something exists in the lunula area that repeatedly causes bleeding, so compared with a simple bruise, it is a bruise that requires careful observation.
..........................................
This is another one of the many questions.
It is a bruise.
If it occurs after walking a long time or exercising, it disappears after about 5 months.
This is a simple melanonychia.
It occurs from melanocytes.
It is a typical melanonychia, but in a certain percentage it can be malignant.
So we always distinguish it with a biopsy.
At our hospital, the test takes about 5 minutes with almost no wound or pain.
It is a line, but a little different, right?
It looks the same as a simple line.
However,
it is a case that makes us very alert and pause to collect ourselves once again.
It appears to be a simple melanonychia.
Anyone would think it is simple from the photo.
However,
the test result shows malignant melanoma.
This photo is an important case that reminds us of the importance of testing.
This one also does not look very pretty.
In this photo, besides the uneven surface, a simple line is visible in the center.
From the outside, it clearly looks like simple melanonychia.
However,
in this case, the result is melanoma, a malignant cancer.
It is another instructive photo that shows the importance of testing.
These are various cases.
Nail melanocytes appear black, brown, or gray.
The photo above shows a gray appearance.
After doing many tests, it shows that we must not deviate from the principle
and must stay faithful to the basics.
The black color is strong and has no clear border.
It also tends to spread and is irregular.
On examination, it is malignant melanoma.
Overall, the black color is strong.
There are multiple lines, and the color is varied.
On examination, it is malignant melanoma.
This is a crust of blood next to the nail that is easy to overlook.
After repeated disinfection over and over, the patient visited our hospital, and the biopsy result
showed Bowen’s disease, a type of skin cancer.
It is a photo that makes us feel grateful for the value of testing.
...............................................................................
This was a case where toenail fungus treatment had been done at another hospital for a long time, but there was no improvement and bleeding kept occurring.
On examination at our hospital,
it was diagnosed as squamous cell carcinoma, a skin cancer.

This also looks like toenail fungus.
It resembles toenail fungus.
It was a case that came in after being treated as toenail fungus at another hospital, but there was no improvement.
On examination at our hospital,
it was also diagnosed as squamous cell carcinoma.

This is advertising time.
You must make a reservation (02-3431-1500) before coming,
and if you send a photo to the question phone (010-9682-1501), I will answer.
This is how treatment is carried out in detail.
This is from my days as an enthusiastic nail and toenail enthusiast in my 30s.
This is a photo from my appearance on SBS Morning Wide.
As time passed, this is a photo from my appearance on MBC Live Today Morning.
The heat continues.
Please take care of your health,
and I wish you great good fortune.
