<s>[INST] Son is 6yrs old almost 4ft tall and around 55lbs. He has had no rash or anytime of problem. He went to his fathers for the weekend and sat had a rash on his privates from what his father told me. He put rash cream on it. This morning he called and said it was horrible and the skin was peeling of his penis, testicles and crack of bottom! He took him to doctor (which is known for not good service in our small town) He gave him cream and said it was a fungus and should be fine in acouple days! Im so scared and worried I have never seen anything like this and we have never had a rash or any other problem of this nature. Should I be worried? Should I take him to er? Would a fungus cause something like this that fast? I tried to call doctor and could not contact him and my exhusband did not ask many ?s! PLEASE HELP [/INST] Hi, The rash on genital and scrotum of your son may be most probably insect bite dermatitis. There may be erythematous, vesicular,fissure rash on penis and scrotum.it might occur after insect bite or insect toxin contact. There may be burning pain and itching. You immediately consult nearby dermatologist. He might give antihistamines, antibiotics and steroid in tampering dose. Antibiotic cream may be applied. Avoid soap bath. Use antiseptic like detail for bath. Let him take rest for few days. He might alright in few days. I hope you got my answer. Thanks. </s>
