Complete skin remission of Sneddon-Wilkinson disease with acalabrutinib.

Sneddon-Wilkinson (SW) disease is rare condition which typically occurs in the context of a monoclonal immunoglobulin and treatment options have not been well studied. Here we present a case of a 65-year-old female with SW with underlying, otherwise indolent, lymphoplasmacytic lymphoma (LPL) with an IgA paraprotein, who achieved a complete skin remission with the administration of the Bruton Tyrosine Kinase inhibitor (BTKi), acalabrutinib.
