AbstractA 60-year old man living in Srinagar (Jammu and Kashmir) had air-borne contact dermatitis for last 10 years. He had never traveled to any other part of the country where Parthenium hysterophorus or Xanthium strumarium are prevalent but he used to cultivate chrysanthemums. Patch tests with standardized extracts of various plants revealed the strongest reaction with Chrysanthemum, while the reactions with Xanthium strumarium and Parthenium hysterophorus were also positive but milder. This seems to be a case of primary sensitivity to Chrysanthemum with cross sensitivity to Xanthium strumarium and Parthenium hysterophorus.
