[Pediatric Gliosarcoma: Case Report and Literature Review].

Brain gliosarcoma is a rare variant of glioblastoma multiforme that occurs primarily between the sixth and seventh decades of life. Few cases have been reported in patients younger than nineteen years. We report a four-year-old male with clinical, imaging and pathology compatible with brain gliosarcoma.

[Orbital tumors: experience with 35 cases].

Tumors of the orbit are pathology of considerable complexity in management due to the diverse anatomic and muscular, vascular, cartilagenous and neural components present. We review a series of 35 cases managed at the National Institute of Cancer in Bogota, Colombia. We determine variables such as age, sex, symptoms, histology, location and surgical procedure of these tumors.
