british boy, 15, develops "toasted bowels syndrome" from keeping a phone on his belly many hours dailyhttps://casereports.bmj.com/content/19/9/e270756android mobile phones maybe gets hot in prolonged use, doctor says"The marks on skin were described as being in a patch about 5 centimeters wide, made of flat, reddish-brown 'interlacing lines forming irregular circles and a lace-like morphology"Based on the appearance, the doctors started reconsidering some sort of bruising and started asking him more questions. "Did someone punch you on stomach daily?"The boy would deny that.This is when he mentioned that he was using a phone while he is on a bed. He said he is resting his phone on his abdomen while music comes out of attached headphones (not wireless headphones).Not only that but while doing this the phone was often plugged into wall charger (a charging phone heats more than one that is not being actively charged)Then the doctor understood what it was.The doctors diagnosed the boy with igna natura renovatur integra (INRI)this is sometimes called "toasted skin syndrome" in EnglishResearchers hypothesize that chronic heat exposure leads to damage to superficial blood vessels and the release of red blood cells, forming the tell-tale red reticulated pattern.Doctors told the boy to not keep a phone resting on any of his body parts. "at least wear a shirt" he ordered.
