Abstract:
Type I hypersensitivity reactions following ingestion of peanuts and tree nuts are well characterized. Cutaneous hypersensitivity reactions are less well characterized, yet they remain the second most common reaction pattern to contact with or ingestion of such nuts. We present a case of a patient who experienced an acute vesicular cutaneous reaction after prolonged contact with pecans. This case illustrates the salient features of contact dermatitis and serves as a reminder that contact with allergenic foods can lead to hypersensitivity reactions.

The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
01:11Papillary 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.
