Answer and Explanation 15

15.  B is the correct answer.  This rash is characteristic of impetigo.  It has this yellowish crusty material on the surface of a plaque.  Causative organisms include staph aureus and strep pyrogenes.  Oral and topical antibiotic therapy should be targeted at that.  Herpes zoster has more of a vesicular or ulcerated appearance and does not have a crusty surface.  Tinea has more of a desquamation appearance to it and does not have the yellow crusty material.  Eczema is typically a lighter more pink patchy lesion.
