acantholytic dermatoses

Example

 pemphigus
 transient acantholytic dermatosis (or Grover disease)

• It is a polymorphic, pruritic, papulovesicular dermatosis characterized histologically by acantholysis, with or without dyskeratosis.
• Once confirmed, most cases of Grover’s disease last six to twelve months, which is why it was originally called "transient".
• However it may last much longer.
• Nevertheless, it is not to be confused with relapsing linear acantholytic dermatosis.

 linear acantholytic dermatosis

Synopsis :

 acantholysis

• loss of desmosomal attachment
