**7.5 Located forms**

It has been described as located subtypes of SS cases with clinical lesions limited to a particular body´s area. The neutrophilic dermatosis of the dorsal hands shows characteristics as much SS as pyoderma gangrenosum exclusively located in this area. There is a controversy about if this entity is a subtype of SS or it is an independient disease (Walling et al, 2006; Laguna et al, 2007; Takahama & Kanbe, 2010). The same consideration is discussed about the located form in facial region (Whittle et al, 1968).
