Cellular schwannoma of the posterior tongue: a rare case report with a literature review

Discussion:Histologically, all schwannoma tumors are encapsulated. Under the capsule, there are 2 specific patterns associated together, but they can be easily differentiated from each other. The first one is made up of firmly aggregated Schwan cells arranged in rows with palisade and enlarged nuclei which are known as Antoni type-A.

The second one is the Antoni type-B that consists of weakly packed Schwann cells.Conclusion:Tongue schwannoma is regarded as a solitary encapsulated benign tumor that may cause complications like difficulty in phonation. The primary treatment modality usually is transoral excision.
