We describe our experience with an interesting case of a salivary calculus in the parotid gland duct that was suspected to be caused by a penetrated fish bone. The patient was a 38-year-old man with swelling and pain in the left buccal region while eating. Radiographic examination showed a radiopaque body in the left buccal region. It was suspected to be a salivary calculus and surgically removed. The foreign body appeared to be a fish bone surrounded by calcification in a parotid salivary duct. The fish bone measured 16 × 0.4 mm and was surrounded by a yellowish white, spindle shaped calcified mass, measuring 4.3 × 2.3 mm. Histopathological examination suggested that a fish bone had penetrated the parotid salivary duct and a sialolith developed around it.
