Easter egg hunt dermatitis: systemic allergic contact dermatitis associated with chocolate ingestion.

Area of Science:

• Allergy and immunology
• Pediatric dermatology
• Contact dermatitis

Background:

• Nickel is a common contact allergen, frequently causing allergic contact dermatitis.
• Systemic reactions to nickel, though less common, can manifest as dermatitis.
• Previous reports link cocoa consumption to nickel-induced systemic reactions.

Purpose of the Study:

• To report clinical cases of pediatric systemic allergic contact dermatitis associated with chocolate consumption.
• To highlight the role of dietary nickel in triggering systemic reactions in sensitized children.
• To increase clinician awareness of nickel-rich foods as potential allergens.

Main Methods:

• Case series presentation of four pediatric patients.
• Clinical observation of hypersensitivity reactions temporally related to chocolate intake.
• Review of existing literature on nickel allergy and dietary triggers.

Main Results:

• Four children presented with systemic allergic contact dermatitis.
• Symptoms were temporally associated with chocolate consumption, particularly around Easter.
• Chocolate, a known source of dietary nickel, is implicated as a trigger.

Conclusions:

• Foods high in nickel, such as chocolate, can provoke systemic dermatitis in children with known nickel sensitivity.
• Clinicians should consider dietary nickel sources when evaluating pediatric patients with unexplained dermatitis.
• Increased vigilance for dietary triggers is crucial for managing nickel allergy in children.
