[|Human|] Over the last few years my son, now 12, gets bright red rashes that cover his arm, hand, palm & sometimes his back on his left hand side. There is no itching or pain, and it does not bother him at all, nor is there any noticeable change in his overall health ... but it is very noticeable & unsightly, & he feels quite aware of it as he gets older. He is an extremely active, physical child & is a very good sportsman - this doesn t seem to affect him physically at all. Any ideas what it is, or what I should do? Hate to miss something. Thanks
[|AI|]  Hi, Asymptomatic red skin lesions could be due to viral infection. Check for fever or any associated symptoms. Other causes could be a purpura.  The diagnosis could only be made by a Dermatologist after proper consultation. I request you to kindly visit your Dermatologist to confirm the diagnosis and to initiate proper treatment. Hope I have answered your query. Let me know if I can assist you further.
