[Otolaryngologist approuch of tumors of mid-line location. A case study].

Congenital tumors of midline location are infrequent. Their highest incidence is before 3 years old. They can be localized on the surface of the skin or have a connection to the central nervous system. The diagnosis can be established by clinical examination, image study and biopsy. The present study describes the clinical case of a six year old boy with a fast growing swelling, located close to the inner orbit of the right eye and off the mid-nasal line. The diagnosis was established by TC (computerized axial tomography) as well as FNAB (fine needle aspiration biopsy), concluding it was a dermoid cyst. Literature was revised focusing our attention on the way of appearance, differential diagnosis and possibilities of treatment for these tumors.
