- Malignant solitary fibrous tumor of the thyroid: a case-report and review of the literature(2014) ALVES FILHO, Wellington; MAHMOUD, Renata Regina da Graca Lorencetti; RAMOS, Daniel Marin; ARAUJO-FILHO, Vergilius Jose Furtado de; LIMA, Patricia Picciarelli de; CERNEA, Claudio Roberto; BRANDAO, Lenine GarciaSolitary fibrous tumor (SFT) is an uncommon spindle-cell neoplasm that most often involves the pleura, rarely occurring in extra-thoracic locations. Twenty-six cases of SFT arising in the thyroid gland have been described. We report a case of a 60-year-old woman presenting an 8-month history of enlargement of the neck associated with dysphagia. The patient underwent a right hemithyroidectomy and SFT of the thyroid was diagnosed. Immunohistochemistry showed positivity for CD34 marker, and the high number of mitoses and the presence of cellular atypia suggested that the tumor was malignant. To our knowledge, this is the second case of malignant SFT of the thyroid gland ever reported. Due to the rarity of these tumors, the indication of adjuvant therapy and prognosis are uncertain. Long-term follow-up after surgical resection seems to be advisable.
