Protein Causes of Urticaria and Dermatitis

Protein contact dermatitis is a cutaneous hypersensitivity reaction after chronic, recurrent exposure or chronic irritation to animal or plant protein. Although the pathophysiological mechanisms underlying protein contact dermatitis are not well characterized, protein contact dermatitis is thought to be caused by combined type I/IV-mediated, type-1 mediated, or a Langerhans cell immunoglobulin E –mediated delayed hypersensitivity reaction. This chapter reviews the epidemiology, pathogenesis, clinical features, common protein allergens, diagnostic process, treatment options, and prognosis of protein contact dermatitis.
