Abstract

Congenital teratoma is a rare condition and is a germ cell tumor composed of elements from one or more of the embryonic germ layers and contain tissues usually foreign to the anatomic site of origin. We report a case of a neck tumor diagnosed during pregnancy, initially thought to be a goiter. After birth the neck mass kept growing until it compressed the trachea and produced respiratory failure. The infant had a difficult tracheal intubation because of the compressing mass. The staff decided to surgically remove the neck mass. After that, the infant became eupneic. The histological analysis showed a mature teratoma with no atypias.

Highlights

Congenital thyroid teratoma is a rare condition[1,2]
We report a case of an infant with a neck mass diagnosed by ultrasound during pregnancy which was initially supposed to be a congenital goiter
The goiter kept growing after birth until it caused severe respiratory distress by compressing the trachea, requiring immediate tracheal intubation

Summary

Introduction

Congenital thyroid teratoma is a rare condition[1,2]. We report a case of an infant with a neck mass diagnosed by ultrasound during pregnancy which was initially supposed to be a congenital goiter. He remained in nasal continuous positive airway pressure (CPAPn) for 7 more days, and after that was kept on oxygen therapy for 10 days He was discharged from the hospital 50 days after birth, still presenting with a laryngeal stridor that was attributed to tracheal malacia by the doctors that initially treated the patient. After hospital discharge, he was observed by a pediatric endocrinologist who started research on thyroid disorders. Levothyroxine was started (25μg, once a day) as thyroid hormone substitute therapy and the infant is thriving well according to the pediatric endocrinologist that continues following the patient
