ABSTRACT
A 47-year-old African American woman presents to the dermatology clinic for the evaluation of a recurrent rash on the right leg. She states that the rash began 3 months ago, shortly after she was treated with amoxicillin-clavulanate for a bacterial sinus infection. The rash seemed to improve after the infection resolved but since then, the rash has recurred at least once every 2-3 weeks. She believes that the rash returns in almost the exact spots on the body and does not seem to spread. On examination, there are two distinct, well-defined round violaceous plaques with a border of erythema on the right upper leg (73). She is otherwise healthy but does report occasional ibuprofen use for minor joint pain.
