Histological patterns of inflammatory skin diseases

Abstract

Dermatopathology is one of the most valuable diagnoses in skin disease in all animal species. Pattern analysis method in histopathology reading has revolutionized dermatohistopathology and has permitted a better approach to the final diagnosis of dermathopaties. There are nine basic histological patterns: superficial perivascular dermatitis, superficial and deep perivascular dermatitis, nodular and diffuse dermatitis, intraepidermal vesicular and pustule dermatitis, subepidermal vesicular and pustule dermatitis, perifolliculitis, folicullitis and furunculosis, fibrosing dermatitis, vasculitis and panniculitis. These patterns create a list of differential diagnosis, which easily lead to the final diagnosis. It is important that clinicians and pathologists know and work together in the use of these patterns.
