A giant dental calculus suspected to be a neoplastic lesion is reported.<BR>The patient was a 50-year-old woman. She had severe anemia caused by a uterine tumor.When she was treated for anemia at the hospital, an internist found an abnormal and extremely large hard mass in her mouth. She was referred to us for treatment of the lesion in her mouth after the transfusion therapy.<BR>At presentation, we noticed that the patient had an extremely bad oral odor and poor oral hygiene. As for the giant mass of the oral floor, a neoplastic lesion was suspected because of its morphological features. The final diagnosis was a dental calculus on three-dimensional computed tomography, scintigraphy, and pathological biopsy.<BR>The giant dental calculus was carefully removed, and the patient was instructed to maintain a sufficient level of oral hygiene to keep her mouth clean. The weight of the removed calculus was 30.5 grams. For 2 years 11 months, no redeposition of dental calculus has occurred.
