Abstract

Mature teratomas of the mediastinum, the most common extragonadal germ cell tumors in adults, usually arise within the anterior mediastinum. In contrast, the neck is an uncommon site for a teratoma. We report an unusual case of mediastinal mature cystic teratoma that extended to the neck. A 28-year-old woman presented with progressive, painful neck swelling, which compressed the trachea and deviated it to the right. Computed tomography (CT) of the chest revealed a cystic mass occupying an area from the anterior mediastinum to the cervical area; the lesion consisted of multiple tissue elements, including soft tissue, fluid, fat and calcification. The cystic mass was resected and the pathological diagnosis was a mature cystic teratoma. To the best of our knowledge, a mediastinal teratoma seldom presents as a neck swelling. Although a rare manifestation, it should be considered in the differential diagnosis of neck masses in adults.
