Heterotopic glial tissue in tonsil: a case report.
J Pak Med Assoc Jan ;55(11):507-8.

We describe a six month old boy with a mass in the left tonsil. It was present since birth and was enlarging progressively. It was completely excised. Histopathology showed a choristoma of neural origin composed of glial cells - astrocytes in a fibrillary background, and a choroid plexus. Immunohistochemistry confirmed the findings.
