Medical Eponyms
Asboe-Hansen sign

The Asboe-Hansen sign (AKA the indirect Nikolsky sign or Nikolsky II sign), refers to the extension of a blister to adjacent unblistered skin when pressure is put on the top of the bulla.

The Asboe-Hansen sign is a useful clinical tool for diagnosing toxic epidermal necrolysis (TEN); and can be employed to generate a fresh bulla for lesional skin biopsy in the evaluation of TEN

A spreading of blisters can be artificially induced by slight to moderate external finger pressure in pemphigus vulgaris (acutus), pemphigus foliaceus, pemphigus vegetans and bullous pemphigoid (pemphigus vulgaris chronicus). The sign is characteristic, although possibly not absolutely specific, of the pemphigus group of diseases.

It reflects a reduction or loss of intercellular bridges between epidermal cells or a dermalepidermal lysis. In the new area of the expanded blister, the microscopic picture of a spontaneous fresh blister is reproduced.
