Eraser Rhinolith: A case report

Nasal foreign bodies are usually received in otolaryngology practice. Although more frequently seen in pediatric patients, also they can affect adults, specifically those with mental retardation or any psychiatric problems. We presented an unusual case of the nasal foreign body, an eraser rhinolith in a 17-year-old boy with mild mental retardation presented with long-lasting nasal obstruction but no chronic infection or epistaxis. Computed tomography revealed a peripherally calcified sub-mucosal round mass in the left nasal cavity. After surgery, a round shape foreign body that looked like an eraser piece was removed from the nasal cavity. Rhinolith can present just with nasal obstruction. With properly diagnosed and appropriate surgery, all rhinoliths can be removed and complication of extraction can be minimized.
