下唇に生じた小唾液腺導管内唾石の1例 A case of sialolith in the minor salivary gland duct of the lower lip
Sialoliths mainly occur in the major salivary glands and rarely arise in the minor salivary glands. Sialoliths in the lower lip are extremely rare.<BR>We report a sialolith occurring in the minor salivary gland duct of the lower lip. An 84-year-old woman was referred to our hospital because of a tumor of the right lower lip. The clinical diagnosis was a benign tumor. We performed tumor excision. There were no adhesions of the surrounding tissue, and the tumor was excised without any problems. Histologically, fragments of calcified material were seen within a dilated duct. The duct epithelium consisted of pseudostratified ciliated columnar epithelium. A minor salivary gland near the duct showed acinar atrophy and fibrosis. The histopathologic diagnosis was a sialolith in the minor salivary gland duct. The patient's postoperative course has been good, with no evidence of recurrence.
