[Pasteurella spp: a new microorganism to the cause of acute suppurative thyroiditis].

Acute suppurative thyroiditis is an uncommon disease due to local resistance of the gland to infection. Preexisting gland pathology and local anatomic abnormalities are predisposing factors. We present the first case described in the medical literature caused by Pasteurella spp after upper respiratory infection with insidious manifestations resembling subacute thyroiditis. The course was benign after surgical drainage.
