A 2 year-old-girl admitted to our department with a chief complaint of a mass on the tongue base. Resection of the lesion was carried out under a clinical diagnosis of the benign tumor and followed up for 2 years. Pathological examination of the tissue showed the thyroid tissue which is not malignant. A normal thyroid gland was proved to be present in the neck by the CT scan and thyroid scintigram.<BR>Lingual thyroid with cervical thyroid is comparatively rare. Montgomery reported that the lingual thyroid without the cervical thyroid was 65 per cent.<BR>We surveyed 172 cases of the lingual thyroid for the last 87 years in Japan. There was the ratio of 1 to 5 between male and female, female predominated. Age was most in teens. Lingual thyroid with absence of the cervical thyroid gland was 58. 1 per cent.<BR>Thyroid-function tests and the thyroid scintigram are necessary on the posterior dorsal surface tumor of the tongue before treatment.
