"Old man, you stretch out your hand, I'll take a closer look."

Zhao Sheng said to the old lady.

"Don't worry, I won't touch it."

After a pause, Zhao Sheng looked at the frightened old lady and said.

"Doctor, say okay, you don't touch it!"

The old lady closed her eyes tremblingly, gritted her teeth, and stretched out her left hand in front of Zhao Sheng.

Zhao Sheng carefully observed the old lady's left thumb, well, the overall color of the thumb looks ruddy, and the color of the nail bed is also normal, and there is no gray part.

After a closer look, Zhao Sheng found that something was wrong, at the root of the old lady's left thumb nail, there was a dark red lump the size of a soybean.

This small mass is dark red, very similar to the color of the nail bed, and if you don't look closely, you won't notice it at all.

Is this the problem?

Zhao Sheng couldn't help but think.

Because of this small lump, the color difference between the color and the nail bed is very small, that is, with Zhao Sheng's current super observation, he can see it at once.

It seems that the old lady has been looking at it so many times before, and it seems that no one has noticed this small lump under the armor.

Thinking of this, Zhao Sheng casually picked up a cotton swab from the table.

"Old man, I'll give you a check-up later, you bear with me."

Zhao Sheng said to the old lady.

"Mom, just bear with it, what if you find out this time?"

The old lady's son also said to the old lady.

"Doctor, come on!"

The old lady mustered up her courage at this time, stretched out her left hand, and said to Zhao Sheng as if she was going to be heroic.

In the past two years, she has really been tortured into a nervous disorder.

"Okay, bear with me."

Zhao Sheng picked up the cotton swab and used the root of the cotton swab to gently press it on the dark red mass on the nail bed.

"Ouch. Doctor.. Hurt! ”

The root of the cotton swab only touched the small dark red lump under the nail bed, and the old lady screamed.

Positive pin compression test!

Seeing the old lady's violent reaction, Zhao Sheng was sure at once.

This pin compression test is specific for subungual glomusoma.

A positive test, combined with a small dark red mass under the nail bed, can confirm the diagnosis of subungual glomus tumor.

So what is a subungual glomusoma?

Subungual glomusoma, is a rare benign small hemangioma, rarely malignant, located under the dermal reticular layer, originating from normal arterioles, venous shunts, with an organ-like structure, composed of hemangiogloma cells, about 1mm in diameter, surrounded by unsheathed nerve fibers.

It is more common under the fingers, toes, and nail beds, and is mostly single, more common in young and middle-aged people, and slightly more in women than in men.

The most significant feature of this disease is that the local severe pain has significant tenderness and spontaneous pain, which is very intense, like a needle prick fire.

Seeing the change in Zhao Sheng's expression, the old lady's son couldn't help but ask with a glimmer of hope: "Doctor, what's going on with my mother's illness?" ”

"The initial suspicion is that it is a subungual glomus tumor, but an MRI of the finger is needed to confirm the diagnosis."

Zhao Sheng said.

In fact, from the point of view of palpation and inspection, the diagnosis of the old lady's subungual glomus has been very clear, and the reason why it is necessary to do another MRI examination of the finger is also to have imaging examinations to support the diagnosis.

After all, this old lady's subungual glomus is going to be operated on, and if you want to do surgery, you must have imaging tests to support the diagnosis.

"Subungual glomus tumor? What is this disease? Isn't it paronychia? ”

The old lady's son asked with a puzzled expression.

This is the first time he has heard of this disease.

Even the old lady looked at Zhao Sheng with some excitement at this time, she had already seen so many diseases, and this was the first time that a doctor could say with such certainty what kind of disease her finger hurt.

"To put it simply, it is a small hemangioma under the nail bed, that is, under the root of the nail, and once the small hemangioma is pressed or stimulated, severe pain will occur."

"If the nail is extracted, it only temporarily relieves the pressure of the nail on the small hemangioma under the nail bed, so it can only relieve the pain for a short period of time at a time."

Zhao Sheng patiently explained to the mother and son.

"Doctor, can my mother's disease be cured?"

When the old lady's son heard Zhao Sheng say this, he had mixed feelings, on the one hand, he could finally determine what the disease was, and on the other hand, he felt that he had not been diagnosed after seeing the disease so many times, what if it was a terminal illness?

"Doctor, I heard clearly, my finger has a tumor, and it needs to be chopped off, no, it needs to be amputated, right?"

"Doctor, come on, I'm here today, that's what I'm going to do!"

The old lady seemed to understand Zhao Sheng's explanation, and said very firmly.

"Old man, the cause of the severe pain in your finger is this subungual hemangioma, so as long as this small hemangioma is removed, you will be fine, and you don't need to amputate your finger."

Hearing the old lady say this, seeing her look of being determined and ready to chop her hands, Zhao Sheng couldn't help but explain with some tears and laughter.

Why does this old lady always think about chopping her hands?

"Is there really no need for amputation?"

The old lady still said in disbelief.

"I really don't need to, let's go for a test first, and when the test results are confirmed, I will be hospitalized for surgery."

Zhao Sheng said slowly.

"Huh? Doctor, do you really see my illness? Just look at it and poke it? ”

The old lady still said in disbelief.

I've seen it so many times before, but I'm not completely sure what is going on with her, how did she get to Zhao Sheng, just look at it like this, take a cotton swab and poke it, you can determine what kind of disease she has?

"Subungual glomus tumor, this disease is rare, if you don't happen to know about this disease, it's hard to think about it."

Zhao Sheng explained.

This is the role of intellectual experience, as well as clinical thinking.

In clinical practice, sometimes there are blind spots in knowledge and thinking, just like this subungual glomusoma, the cause is not complicated, that is, there is a hemangioma on the nail bed, which causes severe pain.

But if you haven't been exposed to, or even heard of, this rare disease, you can't imagine it.

Thinking is important, just as before the invention of the horseshoe, the fate of a horse depended on the degree of wear and tear of the horse's hooves, because no one ever thought of putting boots on the horse's hooves.

This is particularly evident in clinical practice.

In many cases, patients do not receive effective treatment, either incurable or unthinkable.

"Mom, the doctor is a doctor, so you can believe what the doctor said."

The old lady's son is quite knowledgeable, and he can understand what Zhao Sheng said.

"Ah Hui, Mom listens to you."

The son said so, and the old lady also nodded.

However, she was still a little skeptical, because Zhao Sheng looked very young, if it was Zhao Sheng's image before, it would definitely make the old lady trust it all of a sudden.

But Zhao Sheng's hair has grown back, and the temperament and image of the whole person have simply been improved by plastic surgery, which is not at all the same as the gray-haired old professor in the old lady's impression.
