Abstract:
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.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
