Giant cervical teratoma masquerading as lymphatic malformation

Teratomas are composed of multiple tissues foreign to the organ or site from which they arise. They are tumours which consist of solid or organoid masses containing tissues derived from all three or any of the three blastodermic layers. Their histologic features are heterogeneous and may include cystic or solid areas as well as mature and immature components. They can develop from any part of body. The commonest area of occurrence is sacrococcygeal region followed by retro peritoneum. They rarely occur in cervical region.
