We experienced a case of a salivary calculus which contained a limb of a shrimp. The patient, a 37 year old male, was referred to our department complaining of a swellingin the right side of his submandible which increased in size and was painful while eating. The salivary calculus in the right submandible duct was diagnosed from the occlusal radiogram findings. When the calculus was removed it was found to be the size of a grain of rice with a stick-like object pierced through it. Pathological findings seemed to show a stratiform structure of calculus around the foreign body at the center. However, when the cut surface of the salivary calculus was examined for the distribution of Ca and P by a computer aided microanalyzer (CMA) and observed by the scanning electron microscope, it was suspected that the beginning point of the calculus was in another area next to the foreign body. As to the foreign body, it stuck in the floor of his mouth when the patient ate a fried shrimp 3 years ago. The findings obtained from the limb of a shrimp specimen being structurally similar, the foreign body was suspected of being the limb of a shrimp.
