Double Ectopic Thyroid Gland in a 10-Year-Old Filipino Boy

Results: A 10-year-old boy presented with hoarseness and easy fatigability for 6 years. Rigid endoscopy and CT scan showed an infraglottic mass originating from the anterior tracheal wall causing obstruction. Biopsy revealed thyroid tissue with atypia. Thyroid scintigraphy showed uptake in the submental and midline anterior neck. Thyroid hormone levels were consistent with hypothyroidism. Levothyroxine returned hormone levels to normal and resulted in complete regression of the mass with no symptoms of dyspnea, stridor or bleeding.
