Botanical Briefs: Primula obconica Dermatitis.

Primula obconica, a household plant originally found in China that was introduced in Europe in the 1880s, has been reported to cause plant-induced contact dermatitis (CD). The condition more commonly is reported in Europe and less frequently in the United States, where the plant is not commonly included in patch testing protocols. Clinical features of P obconica CD can include facial and hand as well as fingertip dermatitis. The main allergens known to cause these findings are primin and miconidin. Treatment of P obconica CD mainly involves avoiding contact with the plant and applying a topical steroid.
