Endoscopic biopsy sampling of tophaceous gout of the odontoid process

Abstract

✓The authors present the case of a 71-year-old man who presented with neck pain, a history of gout, and a mass in the dens. Results of transoral endoscopic biopsy sampling demonstrated tophaceous gout. The patient was treated medically and the pain resolved. Tophaceous gout isolated in the dens is extremely rare and should be considered in the differential diagnosis of masses in this region. With the aid of transoral or transnasal endoscopic biopsy sampling, the diagnosis can be reached in a minimally invasive manner.
