Ectopic Thyroid Tissue: A Case Series

Abstract

Objective: To describe the clinical presentation and course of seven ectopic thyroid patients. Methods: Design: Retrospective Chart Review Setting: Tertiary Government Teaching Hospital Subjects: Seven patients Results: Five patients were female and two were male (ratio of 5:2). Three belonged to the 20 to 30 year-old age group, whereas two were below 10 years of age. All seven were biochemically hypothyroid and ectopic thyroid was found to be the only functioning thyroid tissue.Three patients were managed medically with levothyroxine, while ectopic thyroid was excised in four. Ectopic thyroid tissue was autotransplanted in two cases following excision. Conclusion: The ages of presentation in the present series correspond with the increased physiological demand of thyroid hormone. Thyroid substitution therapy is a must in the presence of clinical and/or biochemical hypothyroidism. Surgical excision should be avoided as far as possible especially if the ectopic tissue is the only functioning thyroid in the body. Surgery is required in selected cases presenting with obstructive symptoms or hemorrhage which are unresponsive to substitution therapy. Auto transplantation of the ectopic thyroid may not provide significant benefit to the patient and more research is warranted in this aspect.
