Scaly Plaque on the Nose

June 14, 2013

Is this lesion the result of an injury, as the boy’s mother suspected, or something else?

The lesion on this 6-year-old boy occupies almost the entire left side of his nose. The mother attributed it to an injury her son had sustained 2½ weeks earlier, when he was hit in the face by a baseball.

What's your diagnosis?
