Introduction
Thyroid carcinoma is the most common type of endocrine malignancy and the cancer with the largest annual increase in incidence in recent decades. They are classified as primary or metastatic. The most common thyroid cancer subtypes include papillary, follicular, medullary, and anaplastic. We aim to present 11 cases of exceptional thyroid malignancies managed in our department.
Materiel and methods
A retrospective study of 11 cases of exceptional thyroid cancer was performed in ENT and neck surgery department Farhat Hached hospital Sousse Tunisia.
Results
Our study included: six cases of lymphomas, a case of insular carcinoma, two cases of thyroid metastasis of lung cancer, a case of neuroendocrine thyroid carcinoma and two sarcomas. On cervical examination, a multinodular thyroid gland was noted in the 6 cases of lymphomas. Cervical lymph node involvement was present in 6 cases associated with laryngeal nerve palsy in 3 cases. Ultrasound demonstrated a multinodular thyroid gland in all cases associated with microcalcifications in one case. CT scan showed lung metastasis in two cases (angiosarcoma and mantle cell lymphoma). A gastroscopy confirmed the stomach localization in a mantle cell lymphoma. A total thyroidectomy was performed in 4 cases. A bilateral lateral lymph nodes dissection was performed in 2 cases. an emergency tracheotomy was performed for 4 patients who presented with dyspnea. Chemotherapy was administrated in 5 cases. The evolution was fatal in 6 cases.
Conclusion
An accurate diagnosis is important despite the immense difficulties. The management remains challenging. The ideal treatment modality should be determined considering the presence or absence of metastases, the patient’s general condition, and the presence or absence of local symptoms.
