Abstract:
Ectopic thyroid tissue an uncommon condition results from abnormal migration of the primitive thyroid bud. This may be the only functional thyroid. Ectopic thyroid tissue may sometimes coexist with the eutopic thyroid gland. Hyperthyroidism in association with ectopic thyroid tissue is very uncommon. We report a rare case of simultaneous involvement of ectopic and eutopic thyroid tissue in a married women of 35 years who was referred to our department for a technetium 99m thyroid scan. Coexisting ectopic and eutopic thyroid tissue due to identical histology may have similar response to various stimulatory and inhibitory factors like hormones and immunoglobulin's. Iodine-131 is an easy to administer and effective treatment for patients with simultaneous Graves' disease in the ectopic and eutopic thyroid tissues.
