title: [Piriform sinus fistula, a new disease].
abstract: Pyriform sinus fistula has recently been described as a new, rare and little known pathology. The process develops as latero-cervical suppurative adenitis or acute suppurative thyroiditis, usually on the left side. Radical surgery is mandatory to avoid recurrence. This congenital malformation must be present in the differential diagnosis of recurrent infectious cervical processes, especially in acute thyroiditis. The only curative treatment is complete exeresis of the fistula after meticulous dissection of the fistulous tract. We present three cases of this pathology. The diagnostic approach and surgical treatment are discussed. The recent literature on this topic is reviewed.
