Arnold's neuralgia caused by solitary fibrous tumor: Case report

Solitary fibrous tumor (SFT) is a mesenchymal tumor which has been identified in a wide variety of localizations, including soft tissues, peritoneum, retroperitoneum, mediastinum, upper respiratory tract, nasopharyngeal sinuses, periosteum and extremities, orbit, major body cavities, intraspinal and intracranial localizations. The authors describe a case of SFT found in the neck of a young patient suffering from Arnold's neuralgia. After surgery, diagnosis of SFT was based on characteristic histopathological findings, especially on immunohistochemical positive staining for CD34 antigen. It has been described also the characteristic patterns making this diagnose sure, focusing the point that cure is possible with complete excision of the lesion.
