Something fishy about this foot rash
There are additional things. First, there has been a florid immune reaction to the fungus with small vesicles along the sides of the toes and the dorsa of the foot. This has subsided and left the peeling, scaly skin. There has also been secondary infection with gram-negative organisms, including pseudomonas. When acute, they give a pungent, fishy smell to the rash. The treatment required includes oral griseofulvin for the tinea, betamethasone cream for the dermatitic component, and a soaking of the toes in diluted acetic acid (vinegar) to eradicate the pseudomonas. You do not need potent oral antibiotics in this case.
