Mr. Hu (pseudonym), 78 years old this year, has been very distressed recently. He is in a tough body and suddenly had his arms covered with rash half a year ago. Not only is it ugly, but it is extremely itchy.
The itchy rash
At first, Uncle Hu thought he was allergic to something he had eaten, and he didn't care. He thought he would be cured in a while. However, half a year later, the rash not only did not disappear, but also spread from the original arm to the whole body, especially the rash on the front chest and neck area, which looked like it was sunburned. There are also raised purple rashes in finger joints, hands, elbows, etc.
The whole body was covered with rashes and itchy, so Mr. Hu came to the hospital for treatment.
After a series of examinations, the doctor told Mr. Hu that the red rash on his body was not an ordinary skin allergy or skin disease, but was called dermatomyositis .
The so-called dermatomyositis is an idiopathic inflammatory disease of the skin that involves multiple systems such as the skin and muscles. As far as current studies are concerned, the pathogenesis of dermatomyositis is not clear, and it may be related to factors such as genetics, environmental stress, and autoimmunity.
From the name point of view, dermatomyositis is a disease that can cause inflammation of the skin and muscles at the same time.

②Gotton sign: Patients with dermatomyositis will have red or purple-red maculopapular on the extended surface of the joint, especially the metacarpophalangeal , the interphalangeal joint or the elbow joint, with irregular edges or fused into tablets, which are often accompanied by skin atrophy, capillary dilation, and pigmentation or loss.
③ Lesions occur around the nails: Patients with dermatomyositis can see capillaries dilated around the nails, irregular thickening of the nail bed, and local pigmentation occurs.
④Rough skin on the palm surface and sides of the fingers: There are many keratinized skin, cracked and rough, similar to the hands of technicians who have been engaged in manual work for a long time, also known as "technician hands".
Muscle manifestations of dermatomyositis:
Clinical observation data show that about half of patients with dermatomyositis will experience neck flexor muscle weakness, which is manifested as difficulty raising the head when lying flat and often tilting the head back. At the same time, due to the involvement of the throat or upper esophageal striatal muscle, dysphagia , moaning, difficulty in pronunciation, and choking and coughing when drinking water will occur.
hand manifestations
It is worth noting that dermatomyositis and tumors also have a certain symbiotic relationship. That is to say, if dermatomyositis occurs, a large number of patients will have tumors accompanied by tumors.
Therefore, after the doctor diagnosed Mr. Hu with dermatomyositis, he kindly suggested that Mr. Hu do another full tumor examination to rule out the possibility of the tumor.
Uncle Hu felt incredible after hearing this. He has always been in good health and can eat and drink. He has rashes and itchy skin. How could it be related to the tumor?
However, Mr. Hu's family was worried, so they followed the doctor's advice and took Mr. Hu for a comprehensive and detailed examination. As a result, a placeholder was found in Mr. Hu's stomach. After gastroscopy biopsy, pathology confirmed that it was gastric cancer !
Fortunately, because the discovery was very timely, the doctor promptly removed the early tumor for Mr. Hu, and only regular reviews were required in the later stage.
So the doctor reminds that if a rash similar to a dermatomyositis occurs, you must pay attention and cannot be treated as an ordinary skin disease. You must conduct timely examinations by professionals, make clear diagnosis, and treat them.
Can dermatomyositis be cured?
Dermatomyositis is a systemic disease with multiple systems involved. Most of the cases are chronic and tend to heal themselves. There are also a small number of cases that will experience recurrence, and the symptoms will alternate between severity and severeness, and the final outcome will still be alleviated.
gastric cancer
dermatomyositis skin manifestations will seriously affect the quality of life, while muscle manifestations will affect life safety. When muscle weakness occurs, if the treatment is not done in time, the prognosis will be very poor. Patients with heart and respiratory system involvement or treatment have little hope of cure, and most of them will die from respiratory failure and or heart failure. How to prevent dermatomyositis in
?
Since the pathogenesis of dermatomyositis is not clear, it is currently believed that most of them are related to ultraviolet factors, viral infection and autoimmunity. Therefore, if you want to effectively prevent dermatomyositis, the main preventive measures include avoiding long-term exposure to the sun, avoiding overwork, actively improving the body's immunity, quitting smoking and drinking, washing hands frequently, developing good personal hygiene, and preventing infection.
