Which term describes inflammation of the skin that mainly involves the papillary dermis?

Explanation:
Dermatitis describes inflammation of the skin that involves the superficial, or papillary, dermis just beneath the epidermis. This layer is where immune cells respond to irritants or allergens, leading to the redness, swelling, and itching typical of an inflammatory skin condition. Erythema can accompany dermatitis as a sign of increased blood flow, but it is just the redness rather than the disease itself. Xerosis refers to dry skin from moisture loss, not an inflammatory process. An ulcer is a deeper lesion with tissue loss, not simply inflammation of the papillary dermis.
