Rash on Top of feet (this time with pict)

[schmuel44]

My son, 23, is a door-to-door salesman for about a month.  Three days ago he developed a itchy, red rash on the top of the left foot, then, the next day the right.  The rash does not involved the toes and is much more advanced, red and weeping serous fluid on the left.  He has not changed anything in terms of foot-ware or detergent.

The itching responded to benedryl but the rash continued to progress.  Tonight he applied hydro-cortisone...don't know how he has responded yet.

Any ideas as to what this is?

Hello,
This rash on top of feet can be due to contact dermatitis, fungal infection or eczematous rash. What you need to do is consult a dermatologist and get a KOH examination of the skin scrapings and a biopsy of small skin sample done if the symptoms persist. KOH examination of the area will clarify whether it is due to fungal infection or not.

Treatment is different for both fungal infection and eczema.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
