左側顎下部に症状を呈し甲状舌管嚢胞と考えられた一例 A case of cyst on the left submandibular region diagnosed as thyroglossal duct cyst
Thyroglossal duct cyst presents most frequently in the midline of the neck, either at or just below the level of the hyoid bone. We describe a thyroglossal duct cyst appeared on the left submandibular region in a 28-year-old woman. The mass was located in the left submandibular region, above the level of the hyoid bone. This mass moved in a vertical fashion on swallowing. CT and MRI examination revealed a cystic structure extending to the left submandibular region from the base of the tongue. The cystic lesion was removed surgically with the patient under general anesthesia. Histopathological analysis revealed a cyst with a dense fibrotic wall; there was no epithelial cell lining, but many ductal structures consisted of single epithelial cell layer were observed in the cyst wall. The clinical and histopathological findings suggested that the lesion was a thyroglossal duct cyst. There was no evidence of recurrence 4 months after surgery.
