Transient Sarcoid Reaction to a Thoracic Schwannoma

Caillaud D, Horo K, Kemeny JL, Michel JL, Toloba Y

Background: Sarcoid reactions to benign tumors are an exception. Only two cases have been reported where these reactions were associated with a benign teratoma. We report a new case where a sarcoid reaction is secondary to a thoracic schwannoma.

Observation: During a uveitis assessment performed on a 53 year-old man who was not displaying any other symptoms, a thoracic schwannoma and mediastino-hilar lymph nodes were fortuitously discovered. Surgical resection of the schwannoma leads to a regression of the mediastinal and hilar lymph nodes without any other medical treatment.

Conclusion: In case of thoracic schwannoma, a sarcoid reaction must be considered if mediastinal lymph nodes are present. Other similar cases are necessary to confirm the validity of this case report.
