“…In a study done by Kar et al ., it was observed that parthenium plays a significant role in the initiation and spread of air borne contact dermatitis and chronic actinic dermatitis (CAD). [ 12 ] A 20-year analysis of antigens causing photoallergic contact dermatitis done in New York showed 11.6% positivity to plant derivatives including sesquiterpene lactone mix. [ 13 ] The coexistence of allergic contact dermatitis (ACD) with CAD is well known.…”

Background:The photopatch test is used to detect photoallergic reactions to various antigens such as sunscreens and drugs. Photosensitive dermatitis can be caused due to antigens like parthenium, fragrances, rubbers and metals. The photopatch test does not contain these antigens. Therefore, the Indian Standard Series (ISS) along with the Standard photopatch series from Chemotechnique Diagnostics, Sweden was used to detect light induced antigens.Aim:To detect light induced antigens in patients with photosensitive dermatitis.Methods:This study was done in a descriptive, observer blinded manner. Photopatch test and ISS were applied in duplicate on the patient's back by the standard method. After 24 hours, readings were recorded according to ICDRG criteria. One side was closed and other side irradiated with 14 J/cm2 of UVA and a second set of readings were recorded after 48 hrs.Result:The highest positivity was obtained with parthenium, with 18 out of 35 (51%) patients showing a positive patch test reaction with both photoallergic contact dermatitis and photoaggravation. Four patients (11%) showed positive patch test reaction suggestive of contact dermatitis to potassium dichromate and fragrance mix. Six patients had contact dermatitis to numerous antigens such as nickel, cobalt, chinoform and para-phenylenediamine. None of these patients showed photoaggravation on patch testing.Conclusion:Parthenium was found to cause photoallergy, contact dermatitis with photoaggravation and contact allergy. Hence, photopatch test and UV irradiated patch test can be an important tool to detect light induced antigens in patients with photosensitive dermatitis.

“…However, Kar et al in their study have noted that Parthenium plays an important role in the initiation and perpetuation of airborne contact dermatitis (ABCD) and CAD. [22] Similarly, Somani has also reported photoallergy to Parthenium. [18] Thus, these agents and particularly the oleoresins from Compositae plants might play a role in inducing the photoaggravation of CAD.…”

Photodermatoses are a group of disorders resulting from abnormal cutaneous reactions to solar radiation. They include idiopathic photosensitive disorders, drug or chemical induced photosensitivity reactions, DNA repair-deficiency photodermatoses and photoaggravated dermatoses. The pathophysiology differs in these disorders but photoprotection is the most integral part of their management. Photoprotection includes wearing photoprotective clothing, applying broad spectrum sunscreens and avoiding photosensitizing drugs and chemicals.

“…However, it should be emphasized to all that avoidance of further exposure can lead to recovery from dermatitis in many cases (5). The rapid growth of parthenium weed in India and its ill effects on the population makes it important to detect all cases of parthenium dermatitis (8). Patch testing is a definitive tool for diagnosing ABCD (9).…”

Parthenium dermatitis is an immuno-inflammatory disease caused by Partheniumhysterophorus and is the most common cause of plant dermatitis in India. Contact sensitivity to parthenium is everlasting, and hence the disease runs a chronic course with exacerbation during summers. Patch testing with acetone or aqueous plant extract is the simplest way of confirming parthenium contact allergy. We report a case of 40yr old female who presented with generalised erythematous and lichenified plaques and was managed effectively with topical corticosteroid and avoidance of allergens.
