Heterotopic Glial Tissue In Tonsil: A Case Report, Nausheen Yaqoob, Zubair Ahmed, Akhtar Husain

Department of Pathology and Laboratory Medicine

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.
