[|Human|] Male 12 yr old child has developed (last 24 hours) a 3 inch across, rash on the quadriceps of his left leg, The rash appears to be mapping underlying veins as it is not solid but appears to follow vein lines, its not bothering him but he says it burns a little if touched, no rashes anywhere else, weather has been quite hot last few day, if that has any bearing - wondering what to do about it please?
[|AI|]  Hi, The rash could be a Telangiectasia which is the visible expansion of skin blood vessels. Try to compress the blood vessel with your finger, if it milks it could be telangiectasia. If you could not able to milk the veins, it could be a purpura. I highly recommend you to consult your Dermatologist for proper diagnosis and apt management. Hope I have answered your query. Let me know if I can assist you further.
