L25.4

Clinical Causes: Direct contact with foods that contain irritants or allergens, such as nuts, spices, or acidic fruits. Prolonged or repeated exposure to certain foods that can cause sensitization. Use of food items or ingredients on the skin, like topical culinary products or food-based skincare items. Occupational exposure in food handling industries where contact with certain foods is frequent. Cross-reactivity from food allergies, where the immune system reacts to similar proteins found in foods and on the skin.

Key Symptoms: Redness and inflammation of the skin where contact occurred Itching and tingling sensations on the affected area Swelling or edema in the contact region Dryness, cracking, or peeling of the skin Possible formation of blisters or oozing lesions in severe cases Localized discomfort or burning sensation

Diagnosis Path: Diagnosis primarily involves clinical examination of the affected skin, a review of recent exposure to potential food allergens, and patient history. Sometimes, patch testing may be performed to identify specific food allergens responsible for the dermatitis. Blood tests are generally not necessary but might be used to rule out other allergic conditions or underlying issues. The goal is to distinguish this type of dermatitis from other skin conditions such as allergic contact dermatitis, atopic dermatitis, or irritant contact dermatitis.

Treatment Protocols: Avoidance of direct contact with known or suspected foods that trigger the dermatitis Wearing protective clothing or gloves when handling foods that cause skin irritation Application of topical corticosteroids or anti-inflammatory ointments to reduce inflammation Use of emollients or moisturizers to keep the skin barrier healthy Identification and elimination of potential cross-reactive foods or allergens Maintaining good skin hygiene and avoiding harsh soaps or chemicals that can irritate the skin Consultation with an allergy specialist for testing and personalized advice
