A 2-year-old presented with a 6-week history of an eruption that originally began with a “pimple”-like sore on his foot. Gradually the lesion extended linearly up the calf and onto the thigh. It was mildly pruritic, and regional adenopathy was evident. Prior treatments with topical and systemic antibiotics as well as topical steroids failed to stop the progression of the disease.

What is the diagnosis and treatment?
