Noneczematous Contact Dermatitis

Table 1

Factors determining the peculiar polymorphic clinical features of allergic contact dermatitis.

Eruptive polymorphism
Evolutive polymorphism
Causative agent
Patient sensitizing level
Way of exposition (cutaneous, systemic)
Means of exposition (cutaneous direct, cutaneous aeromediated)
Tissue structures targeted by the causative agent
Anatomophysiology of the cutaneous region involved
Causative agent possible concomitant irritant action
Environmental factors (UV, temperature, humidity)
Itching intensity variability
Preexisting dermatitis underlying the overlapping contact allergy
