Introduction: Parathyroid carcinoma is a very rare tumor. The reported incidence is between 0.5 to 5% of primary hyper parathyroidy in various series. This entity does not present any clinical or biological specificity compared to the parathyroid adenoma which exposes to diagnostic difficulties.Objective: The aim of our presentation is to study the clinical, therapeutic and evolutionary aspects of parathyroid carcinomas.Material an...

Introduction: Graves’ disease (GD) is an autoimmune disorder characterized by diffuse hyperplasia and excessive production of thyroid hormone. The association between thyroid carcinoma and GD is controversial. Thyroid nodular lesions in patients with GD should raise a high suspicion of carcinoma. The aim of this study is to focus on the possibility of an association between hyperthyroidism and thyroid Carcinoma.Materials and Methods: This is a retro...

Introduction: Anaplasic thyroid carcinoma is an extremely aggressive undifferentiated tumor of follicular cell origin. It is uncommon and comprising approximately 1% of all thyroid cancers.Purpose of the presentation: The objective of this work is to determine the clinical, histological and therapeutic aspects of anaplasic thyroid carcinoma.Methods: This is a retrospective study about 4 patients treated for an anaplasic thyroid car...

Introduction: Thyroid cancer is rare in the pediatric population, but thyroid carcinomas occurring in children carry a unique set of clinical, pathologic, and molecular characteristics. In comparison to adults, children more often present with aggressive, advanced stage disease. The aim of the study is to determinate the clinical, histological and therapeutic aspects of differentiated thyroid cancer in children and adolescents.Materials and Methods: This...

Introduction: Papillary and follicular thyroid carcinoma are the most frequent endocrine malignancy. Lymphatic metastases at the time of diagnosis are common in differentiated thyroid cancer (DTC). In these patients, most authors recommend a thyroidectomy with neck dissection. However, neck dissection can lead to numerous post-operative complications. Thus, careful pre-operative evaluation of cervical lymph node metastasis may be crucial, so that patients do not undergo unnece...

Introduction: Oncocytic tumors (OT) are rare, representing 3 to 10% of epithelial tumors of the thyroid. It is important to individualize these tumors given the relatively high frequency of carcinomas and the aggressiveness of oncocytic carcinoma. The aim of this study is to determinate the clinical, histological and therapeutic aspects of thyroid oncocytic tumor.Materials and Methods: This is a retrospective study about 23 cases of oncocytic thyroid tum...

Introduction: Cervico-facial non hodgkin lymphomas are rare conditions; they represent 5% of all malignant tumors of the head and neck. Their localizations are essentially lymph nodes but all the organs can be affected.Purpose of the presentation: The objective of this work is to determine the clinical, histological and therapeutic aspects of malignant non-Hodgkin lymphoma localized in the thyroid gland.Methods: This is a retrospec...

Introduction: The association between chronic lymphocytic thyroiditis (CLT) and papillary thyroid carcinoma (PTC) has been investigated for several years from different perspectives. In spite of that, there were only few attempts to design a common frame of references to understand the complex mutual interactions between the various pathways of inflammatory response and of thyroid tumor induction and progression. The aim of this study is to investigate the clinical characteris...

Introduction: Neuroendocrine tumors of head and neck region are rare and heterogeneous. it can arise in all the different organs of this region, including the nasal cavity, paranasal sinuses, larynx, thyroid, can be divided into two broad groups: those with epithelial differentiation, and neurally derived tumours, including paragangliomas and olfactory neuroblastomas. Their morphological and clinical features mainly depend on the degree of differentiation and on the site of or...

Introduction: Ectopic thyroid is characterized by thyroid tissue in a location other than anterior to the upper tracheal rings. The estimated incidence of thyroid ectopia is approximately 1/100,000. The most frequent locations are along the midline from the base of the tongue (90%) to the mediastinum. Ectopic thyroid tissue in the lateral neck is rare. We present a case of an ectopic thyroid gland with an atypical presentation as a lateral neck mass.Case...
