[Congenital benign cervical teratoma].

We report a case of a newborn female which showed, at birth, a right cervical tumour of 12 cm of diameter. Macroscopically it was a cystic tumour with a 2 cm nodule. Microscopic examination showed different components such as nervous tissues. Striated and smooth muscle fibers were identified too. Latero cervical fistulas, branchial cysts, cystic hygroma, hemangiolymphangiomas and thyroid tumours must be considered as differential diagnosis.
