Teratomas are embryonal neoplasms that show characteristics of three germ cell layers (ectoderm, mesoderm, and endoderm). They are distributed in the following regions: sacrococcygeal (57%), gonadal (29%), mediastinal (7%), cervical (3%), retroperitoneal (4%), and intracranial (3%) regions. Non-gonadal teratomas present in infancy whereas gonadal are seen in adolescence. Especially, teratomas that occurred in midline neck of adult are very rare and are confused with thyroglossal duct cysts, cystic hygromas, and thyroid tumors. We report, along with the review of appropriate literature, a case of histopathologically confirmed benign cystic teratoma in the midline neck of a 33 years old woman.
