Background: Locoregional nodal metastases are the first step of tumor spread in MTC and have been shown to be a prognostic factor for survival. Neither palpation nor neck ultrasound can estimate nodal staging accurately.Aim: To identify predictive factors for LNI in MTC through a retrospective study on 142 consecutive patients operated in Lille University Hospital between 1995 and 2010.Methods: Analyses were carried on 54 patients ...

Pheochromocytomas are neuroendocrine tumors able to synthesise cathecholamines as well as to metabolise them in metanephrines (NM,M). We assayed Adrenaline, NorAdrenaline, Dopamine and metanephrines in serum (p) and urine (u), and the chromogranin A. We measured 11 parameters (Ap, Au, NAp, NAu, Du, MNp, MNu, Mp, Mp, 3Metu, CgA). Catecholamines and metanephrines were performed using HPLC with electrochemical detection, and CgA with an immunometric as...

Riedel thyroiditis is an uncommon form of chronic thyroiditis in which the thyroid gland is replaced by fibrous tissue. The etiological mechanism underlying RT are unclear. The prevailing view is that it is part of a generalized fibro-inflammatory process also involving other organs. Therapeutic options are not standardized (surgery, corticosteroids, and more recently tamoxifene). The aim of this work is to present three new cases, and the favourable evolution observed in one ...
