A 3-year-old boy presented with history of foul-smelling discharge from the left side of his nose starting 1 day earlier. On examination, there was extensive edema with slough in the left side of the nasal cavity. An X-ray study of the nose, lateral view, revealed a button battery in the nose (Fig. 1). The child was immediately taken to the operation theatre, and endoscopic removal (Fig. 2) of the button battery (Fig. 3) along with debridement of the necrotic tissue was done. The patient is being seen in regular follow-up, and has developed a perforation of the nasal septum that is being managed conservatively at present.
