It is characterized by generalized muscle hypotonia from early childhood, elongated cacial appearance, mandibular undergroth, and dental malposition. In this report, we discuss the clinical course and management of a patient with centronuclearmyopathy, who developed a giant dental calculus in the floor of the mouth and underwent surgical excision.</jats:p></jats:sec><jats:sec><jats:title>Case Report</jats:title><jats:p>A 37‐year‐old Japanese man was referred to our hospital, and reported a swelling in the floor of the mouth. The patient affects centronuclear myopathy and has generalized muscle weakness. CT images showed a high‐density area in the floor of the mouth measuring 35 × 28 × 20 mm. The lesion was clinically diagnosed as giant dental calculus, and surgically removed.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>We have experienced a case of giant dental calculus in a patient with centronuclear myopathy.
