Overview
Salmonella-induced skin eruptions, often manifesting as diffuse pruritic papular or nodular lesions, can occur in individuals exposed to contaminated sources, particularly in occupational settings like farming 1. These eruptions are typically associated with systemic symptoms such as fever 1.Diagnosis
Clinical Presentation: Diffuse pruritic papular and nodular skin lesions 1.
Epidemiological History: Exposure to contaminated food, water, or environments 1.
Laboratory Tests: Stool cultures for Salmonella identification 1.
Skin Biopsy: Rarely needed but can confirm histopathological findings consistent with drug eruption or hypersensitivity reaction 1.Management
Antibiotic Therapy: Initiate empirical antibiotic therapy targeting Salmonella, such as ciprofloxacin or azithromycin, based on local resistance patterns 1.
Symptomatic Relief: Antihistamines for pruritus and topical corticosteroids for skin inflammation 1.
Supportive Care: Hydration and management of systemic symptoms like fever 1.Special Populations
Pregnancy: Limited data; focus on supportive care and avoid potentially teratogenic antibiotics unless absolutely necessary 1.
Pediatrics: Tailored antibiotic dosing based on weight; close monitoring for systemic complications 1.
Elderly: Increased vigilance for complications; consider underlying comorbidities affecting treatment choices 1.Key Recommendations
Identify and Treat Underlying Infection: Initiate appropriate antibiotic therapy targeting Salmonella based on clinical suspicion and local resistance patterns (Evidence: Moderate 1).
Manage Pruritus and Skin Inflammation: Use antihistamines and topical corticosteroids for symptomatic relief (Evidence: Expert opinion 1).
Monitor for Complications: Especially in special populations like the elderly and pregnant women, due to increased risk of systemic complications (Evidence: Moderate 1).References
