Asboe-Hansen sign

The Asboe-Hansen sign (also known as "indirect Nikolsky sign'"[1] or "Nikolsky II sign"[1]) refers to the extension of a large blister to adjacent unblistered skin when pressure is put on the top of it.[2][3] It is seen along with Nikolsky's sign, both used to assess the severity of some blistering diseases such as pemphigus vulgaris and severe bullous drug reactions.[4]

This sign is named for the Danish physician Gustav Asboe-Hansen (1917–1989), who first described it in 1960.[5]

It is considered an indirect diagnostic tool in toxic epidermal necrolysis (TEN).
