On dermatological examination, a thin black plaque with a lighter brown rim was seen on the medial sole.

“I had a patient who came for a consultation after being aggressively treated multiple times for a fungal infection that wasn’t improving. The previous diagnoses were incorrect, as the condition was actually pityriasis rosea. I used VisualDx to show the patient various photographs of the condition, which immediately reassured him and clarified the correct diagnosis.”
