RESUMO
INTRODUCTION: Follicular thyroid carcinoma (FTC) is the second most common thyroid cancer subtype after papillary thyroid cancer (PTC), and it accounts for approximately 10% of all thyroid cancers, the incidence of distant metastasis in FTC has been reported to be 6-20%, bones and lungs are the most frequent sites of distant metastases. Most occult thyroid carcinomas are papillary carcinoma. CASE PRESENTATION: We describe an extremely rare case of a 74-year-old woman who had a history of right thyroid lobectomy 20 years ago, was referred to our hospital for metastatic thyroid follicular carcinoma to the sacral region confirmed by the biopsy of the sacral mass. The patient was treated by analgesic radiotherapy, surgical totalisation of thyroidectomy, and Radioactive Iodine, with thyroid replacement by levothyroxine. In the follow up we noticed a significant symptom reduction leading to a much better quality of life. CONCLUSION: Increasing importance should be given to rare metastases in DTP patients. Early detection will help in the early diagnosis and treatment of the disease, thereby improving the patient's survival rate and quality of life.
RESUMO
INTRODUCTION: Solitary fibrous tumour (SFT), as are benign neoplasms of fibroblastic cells. Nasosinusal localisation is exremely rare, difficult to diagnose and to manage. CASE REPORT: We report a rare case of Solitary fibrous tumour in the nasal cavity in a 47-year-old- woman, with complete surgical resection. DISCUSSION: SFTs are of mesenchymal origin, mainly from serous membranes. The head and neck region is affected with a percentage ranging from 5 to 27%. On the other hand, LTS unusually affects the nasal tract (NTS). Because of this rarity and its variable morphological appearance, it is difficult to distinguish TNS from other mesenchymal lesions. CONCLUSION: Although there are no standard clinical guidelines, the preferred treatment for FLS is radical surgical resection.
