Evolution of clinical pattern of parthenium dermatitis: a study of 74
cases
Vinod K. Sharma1*, Gomathy Sethuraman1 and Radhakrishna Bhat1

Our aim was to study the evolution of clinical pattern of parthenium
dermatitis. Patients with clinical picture consistent with parthenium
dermatitis for 3 years or more along with positive patch test to
parthenium were studied. Patients were questioned regarding the site
(s) of dermatitis at the onset and change in localization in the
following years. Patients were classified into airborne contact
dermatitis, chronic actinic dermatitis (CAD) pattern or mixed pattern
dermatitis. There were 74 patients (49 men and 25 women) with an age
range of 2270 years and the mean duration of 7.7 years. 60 (39 men
and 21 women) patients had airborne contact dermatitis, 5 mixed
pattern and 9 CAD pattern at the onset. Of the 60 patients with
airborne contact dermatitis, 27 (19 men and 8 women) changed to CAD
pattern and 11 (6 men and 5 women) to mixed pattern after an average
period of 4.2 years. Of the 19 patients photopatch-tested with
parthenium, 3 showed photoallergic reaction and the other 3 showed
photoaggravation. Our results suggest that the clinical pattern of
parthenium dermatitis undergoes a significant change after the onset,
i.e. progresses from airborne contact dermatitis to mixed pattern or
CAD pattern.
