An approach to the diagnosis of neutrophilic dermatoses: A histopathological perspective

Neutrophilic dermatoses comprises of non-infective dermatoses which are histopathologically characterized by neutrophil predominant infiltrate and clinically, respond promptly to corticsteroids. Conditions primarily with vasculitis though neutrophilic are excluded from this group. In this article we intend to briefly outline the approach to diagnose these conditions with histological perspective. The ambiguity regarding few recent dermatosis viz, rheumatoid neutrophilic dermatosis, bowel associated-dermatosis-arthritis syndrome etc. with regard to their inclusion in this group has also been highlighted.
