She has been afebrile and has not had any recent travel, outdoor activity, or sick contacts. She has a long history of diarrhea with greasy stools and flatulence. She has tried a gluten-free diet in the past, but she stopped the diet two months ago after her family insisted that it was just a fad and too difficult to accommodate. Since introducing wheat back into her diet, her diarrhea has returned and she developed this rash three weeks ago (Figure A). She has been avoiding gluten for the past week, but the rash has not resolved. Which of the following best describes her conditions?
