Abstract

Summary

BackgroundTulip, belonging to the genus Tulipa and family Liliaceae, is a spring‐blooming perennial that grows from bulbs. Owing to manual handling, contact dermatitis can occur in professionals at any stage of the growth cycle of the tulip plant.

ObjectivesTo determine the clinical pattern of contact dermatitis resulting from tulip plant cultivation, and to assess contact allergy in workers coming into contact with this plant.

MethodsOne hundred and sixty‐four tulip workers were screened, and 48 patients with suspected contact dermatitis were patch tested with 39 allergens, including haptens from the Indian baseline series, a plant series, and extracts from different parts of the tulip plant.

ResultsThirty‐nine positive patch test reactions were observed in 21 patients. Seventeen patients showed positive reactions to either α‐methylene‐γ‐butyrolactone or to tulip plant extract. Clinical relevance was observed for 13 of 17 positive patch test reactions.

ConclusionsContact dermatitis is an important health hazard in workers dealing with tulip bulbs. Further studies to identify and isolate other possible tulip allergens, and to quantify the amounts of allergens in different parts of the tulip plant, are recommended.
