Abstract
- Fibrosarcoma is a malignant mesenchymal neoplasm of fibroblasts that rarely affects the thyroid gland and can cause local recurrences or metastasis. We describe a case of primary fibrosarcoma of the thyroid in a 31-year-old man. Microscopically, the tumor showed highly cellular proliferation of spindle cells with cytologic atypia and mitotic figures. Immunohistochemically, the cells only showed immunoreactivity for vimentin and negativity for S-100 protein, CK, CD31, CD34, TTF-1, desmin. Based on clinical, radiological, histological and immunohistochemical findings, the final diagnosis was intra-thyroid fibrosarcoma. The treatment of choice is radical surgery. Radiation therapy is used as adjuvant treatment. So, we review the clinical, radiologic, histologic findings and treatment modalities of the fibrosarcoma of the thyroid gland.
