Abstract: Anterior neck abscesses are not rare; but their origin from within the usually infection-resistant thyroid gland is not thought of in the first instance. We encountered 3 patients with differing presentations (tender nodule over anterior neck, recurrent abscess overlying the thyroid gland, and nonhealing fistula with inflammation of the anterior neck). These were caused by persistent embryological communication from the pyriform sinus to the thyroid gland to the left lobe. Excluding the first patient in whom an abnormal communication with oropharynx was suspected when actinomyces was detected in the aspiration cytology of a thyroid nodule, the other 2 patients underwent drainage as for any neck abscess. Fistulous communication was confirmed on barium swallow (in 2 patients) or computed tomographic scan (in 1 patient). En bloc excision of the affected thyroid along with the fistulous tract was performed in all patients. Long-term follow-up confirmed a cure. © 2008 Elsevier Inc. All rights reserved.
