Bekabi VT. Primary solitary fibrous tumor of the thyroid gland: a case report. Case Study and Case Report 202; 12(1): 1 – 5. ABSTRACT The thyroid gland's primary solitary fibrous tumor (SFT) is a rare mesenchymal tumor with fibroblastic differentiation, ramified, thin-walled, swollen (staghorn) arteries, and an unique NAB2-STAT6 gene fusion that is more usually observed in the pleura and peritoneum. This neoplasm can occur in a variety of anatomical locations. Examples of places outside the pleura and peritoneum include bone, visceral organs, and soft tissues, as well as the head and neck. Extra-pleural and extra-peritoneal tumors account for only 10-15% of all extra-pleural and extra-peritoneal tumors. This entity's diagnosis can be difficult. Microscopic characteristics, in combination with STAT6 and CD34 positive, help confirm the diagnosis and rule out other possibilities. Differential diagnosis is a term used to describe a thyroid SFTs have little information about their diagnostic and therapeutic choices. Raising awareness of the tumor's extra-pleural and extraperitoneal presence in endocrine organs will help these patients be effectively managed. The case of a 44-year-old woman with primary SFT of the thyroid gland is presented. In addition, we search the literature for the neoplasm's primary clinical, paraclinical, and pathological characteristics. Keywords: Thyroid, mesenchymal, neoplasm
