Summary Airborne contact dermatitis (ABCD) is a commonly occurring form of allergic contact dermatitis with varied aetiology, often posing a diagnostic challenge in management. A study was carried out on patients with a clinical picture and history consistent with ABCD due to exposure to Parthenium hysterophorus (parthenium weed), who were patch tested. There were 50 patients with parthenium‐induced ABCD (36 men and 14 women; age range 24–75 years). The majority (90%) of the patients were farmers and most of the patients (74.5%) had exacerbations during summer. The most common type of dermatitis was the classic pattern (46%) followed by the mixed pattern (30%), erythroderma (14%) and chronic actinic dermatitis (10%). Of the 40 cases patch tested with the Indian standard series of antigens, 36 (90%) cases had patch‐test results positive for parthenium.
