Teratoma congénito de origen intracraneano

Teratomas are embyonic tumors associated with erroneous prognosis at any life stage. We report on a case from the Department of Pathology, San Ignacio University Hospital, Bogota: a female fetus with tumoral mass in the right submandibular region within the right cerebral temporal lobule linked through the ipsilateral sphenoid. An immature teratoma of the central nervous system was histologically diagnosed. The major diagnostic difficulty encountered was determining degree of immaturity, due to the fact that fetal tissue is by definition immature.
