Last year my 7 year old son got what we thought was the flu (temps near 103 degress). With his high temperature he got marbled looking skin. He was eventually hospitalized and given strong antibotics. He got well, his skin got better, but the marbled look never went away. This year during the summer it nearly disappeared with the summer tan. He now has the flu (almost a year later) and the marbled skin is again very prominent. His temps are now only around 101 degrees. He does not complain of itching or pain.
Any ideas what it is?
