Your health care provider may use a pencil eraser or finger to test for Nikolsky sign. The skin is pulled to the side with a shearing pressure on the surface, or by rotating the eraser back and forth.
Similarly one may ask, how do you elicit Nikolsky sign?
A typical example would be to place the eraser of a pencil on the roof of a lesion and spin the pencil in a rolling motion between the thumb and forefinger. If the lesion is opened (i.e., skin sloughed off), then the Nikolsky's sign is present/positive.

What are Acantholytic cells?
Acantholysis. Acantholysis is the loss of intercellular connections, such as desmosomes, resulting in loss of cohesion between keratinocytes, seen in diseases such as pemphigus vulgaris. It is absent in bullous pemphigoid, making it useful for differential diagnosis.
What is a positive Nikolsky sign?
Your health care provider may use a pencil eraser or finger to test for Nikolsky sign. A positive result is usually a sign of a blistering skin condition. People with a positive sign have loose skin that slips free from the underlying layers when rubbed.What is the difference between SJS and TEN?
The difference between SJS, SJS/TEN overlap, and TEN is defined by the degree of skin detachment: SJS is defined as skin involvement of < 10%, TEN is defined as skin involvement of > 30%, and SJS/TEN overlap as 10-30% skin involvement. In SJS/TEN, the most common complications are ocular, cutaneous, or renal.What triggers bullous pemphigoid?

If the DIF result is positive, indirect immunofluorescence (IDIF) is performed using the patient's serum.Why would a blister just appeared?
Causes of blisters Blisters are most often caused by skin being damaged by friction or heat. Certain medical conditions also cause blisters to appear. The damaged upper layer of skin (epidermis) tears away from the layers beneath and fluid (serum) collects in the space to create a blister.Is Pemphigus a cancer?
