Case Report: Mixed Airborne Contact Dermatitis-Chronic Actinic Dermatitis Pattern of Parthenium Dermatitis with Response to Tofacitinib Therapy.

Parthenium hysterophorus is the commonest cause of plant dermatitis in India. It classically causes airborne contact dermatitis (ABCD), characterized by pruritic, eczematous, and lichenified lesions involving predominantly the face and flexural areas. Over time, however, a transition to chronic actinic dermatitis (CAD) pattern, with prominent involvement of sun-exposed sites, may occur.
