Abstract
A 4-year-old boy presented with erythematous vesicular plaques, ulceration, edema, and pruritus on the left foot and ankle 10 days after receiving the tetanus, diphtheria, pertussis, and polio; measles, mumps, rubella, and varicella; and hepatitis A/B vaccines. Biopsy showed eosinophilic infiltrates and flame figures, suggesting Wells syndrome. Patch testing showed a 1+ reaction to neomycin and aluminum hydroxide, with a recall reaction of Wells syndrome of the feet bilaterally. We report a rare case of pediatric Wells syndrome triggered by nonthimerosal vaccine components confirmed by patch testing.
