Teratoma is a rare type of germ cell tumor that consists of structures derived from all three germ layers of the embryo with varying proportions. While most of these are benign, some can turn malignant. The most common location of teratomas is the sacrococcygeal region, while their occurrence in the neck region is very rare. Broadly classified, immature teratomas contain poorly differentiated tissues, while mature ones have well-differentiated tissues. Here, the authors present a case of a 12-month-old child who presented with a huge neck mass. Radiological imaging studies were performed. Under a multidisciplinary team approach, the child was treated successfully with surgical excision. Histopathology revealed the mass to be an immature teratoma of grade III. Postoperatively, no recurrence has been noted.
