Malignant Solitary Fibrous Tumor of the Mediastinum with Multiple Recurrences and a Rare Metastasis to the Thyroid Gland: A Case Report

Abstract

Solitary fibrous tumors (SFTs) are rare neoplasms arising from mesenchymal cells. Although most SFTs are benign, rare cases of metastasis have been reported at various sites. Complete surgical resection is the mainstay of treatment for both primary and recurrent or metastatic SFTs. Herein, we present a case of an SFT initially identified in the anterior mediastinum that later developed multiple metastases, even to the thyroid gland. The patient underwent repeated surgical resection and is currently being followed up in an outpatient setting.
