Among the many things that happen to our body, there is one thing that we are particularly concerned about. That’s the ‘red dot’. Red dots caused by herpes simplex, dermatitis, or petechial hemorrhage are not a big problem, but they may not look good in appearance and may cause complications, so it is necessary to check the characteristics of the lesions.

If the red dots persist for a long time or occur frequently, you should get tested.
When strong pressure is applied to the skin or capillaries burst due to abnormal blood coagulation, temporary bleeding occurs and it may appear as a red dot. This is called petechial hemorrhage, and petechial hemorrhage appears as small dots of 1 to 2 mm or less scattered on the skin. At first, it appears as a vivid red color, but gradually turns brown and fades and disappears after 2 to 3 weeks. Petechial hemorrhage may also occur when the blood vessel walls are weakened or the ability of the blood to clot is reduced due to thrombocytopenia. If petechial bleeding does not go away and lasts for more than a month, it is good to have a detailed examination such as a platelet test.
Lesions such as petechial hemorrhages, or purpura if they are more than 3 mm in diameter are called purpura. Purpura can cause complications if it lasts for a long time. In a paper titled ‘Diagnosis and Treatment of Purpura’ published in the Journal of the Korean Society of Internal Medicine in 2008, “If purpura persists for a long time or if there is bleeding into the muscle layer or joint cavity, a coagulation disorder should be suspected.” We also need to see if there are any other abnormalities in the skin,” he explained. In particular, in the case of allergic purpura, abdominal pain or arthralgia symptoms may accompany systemic symptoms, and in rare cases, lung and brain hemorrhage may occur due to immune cells attacking the lungs and brain, so more attention is needed. In addition, as purpura is neglected, the cycle becomes shorter and the symptoms worsen, so active treatment is required.
Red dots that appear with age should be suspected of ‘cherry hemangioma’
In the case of middle-aged people, if there is a red spot as if red pepper powder was sprinkled, cherry hemangioma should be suspected. Cherry hemangioma is also called senile hemangioma because it tends to develop more and larger with age. It is more common on body parts such as the arms, back, and chest than on the face.
Most hemangiomas do not progress to malignancy and do not necessarily need to be removed. However, if a vascular tumor or vascular malformation disease such as Kaposi’s sarcoma or arteriovenous malformation is suspected as a differential disease, it is recommended to remove it after skin biopsy. If it is not aesthetically pleasing, it can be removed through cryotherapy or laser treatment.
