Pott puffy tumor appearing with a frontocutaneous fistula.

Pott puffy tumor is defined as a forehead-localized swelling with overlying subperiosteal abscess and osteomyelitis of the frontal bone. It is an uncommon disease entity and more rarely reported with its frontocutaneous fistula. We report the unusual case of Pott puffy tumor appearing with a frontocutaneous fistula. We performed a frontal sinus surgery using a combined endonasal and percutaneous approach and frontal bone reconstruction with a resorbable mesh plate and bone cement. During a follow-up 1 year after the surgery, there was no recurrence, and we achieved excellent result from the aesthetic point of view.
