[A case with acute suppurative thyroiditis due to Eikenella corrodens and alpha-Streptococcus].

A 6-year-old girl with acute suppurative thyroiditis is reported. She suffered from suppurative thyroiditis twice, and E. corrodens and alpha-streptococcus were grown from the abscess each time. They were sensitive to antibiotics used, but surgical drainage was necessary to cease to inflammation each time. E. corrodens seemed to be a causative organism with or without another organism in compromised patients and/or patients with anatomical abnormalities. The presented patient was supposed to have some anatomical abnormality such as an internal fistula from the piriform sinus connecting the perithyroidal space, however, no abnormalities were detected during these episodes.
