Subcorneal pustular dermatosis (Sneddon-Wilkinson disease) after a diagnostic echogram. Report of two cases

We reported two cases of subcorneal pustular dermatosis (Sneddon-Wilkinson disease) which developed several hours after performance of an echography. To the best of our knowledge, there are as yet no reports in the literature relating performance of echography with the appearance of this rare disease. The possible explanation of the relation between the dermatologic disorder and the performance of echography is discussed.
