Thyroid abscess due to Eikenella corrodens in a pediatric patient.

Eikenella corrodens is one of the HACEK bacteria that is commensal microorganism of the oropharngeal flora. E. corrodens has been increasingly reported to cause pyogenic abscesses, especially in diabetic or immunocompromised adults. It is less frequently reported in immunocompotent children. Here, we report a deep neck infection, including the thyroid gland, in a previously healthy girl. E. corrodens was the only microorganism isolated in two different cultures. Antibiotic susceptibility is variable, in contrast to other oropharyngeal pathogens. Thus, to avoid delayed treatment, E. corrodens should always be considered in infections of the head and neck area.
