Relapsing suppurative neck abscess after chemocauterization of pyriform sinus fistula.

We report a case of relapsing suppurative neck abscess due to a pyriform sinus fistula ever treated by chemocauterization. Pyriform sinus fistula is rare, and chemocauterization is an alternative microinvasive procedure. This case indicates that the possibility of recurrence following management of chemocauterization exists even after a long time and that clinical radiological assessments are necessary.
