Miss Chen, Jingzhou City, Hubei Province: I am a young man in my 20s, and I don’t know how it happened, but I have a lot of red moles on my body, the number is quite large, almost reaching thousands on one arm, with small but dense particles. In recent years, they have started to spread on the upper body, legs and even face, so how can I control their development? Is it related to heredity? Do I need treatment? A: Since we do not know your detailed medical history and do not have the necessary examination results, we can only speculate from the symptoms you have described that the “red nevus” you mentioned may be a vascular disease, among which diffuse body angiokeratoma or multiple angioglobulomas are more likely, both of which are related to genetic factors; in addition, it may also be It may be a manifestation of a body systemic lesion on the skin. Therefore, we hope that you will go to the dermatology department of your local hospital as soon as possible or send us a photo of the lesion with a description of the condition for diagnosis. The treatment will be determined after the diagnosis is confirmed.
