Some authors proposed that there is a positive linear relationship between tumor size and measurements of metanephrines and an absence of association with catecholamine levels.Objectives: To review and characterize patients diagnosed with PHEO and PGL in Garcia de Orta Hospital. To determine the relationship between tumor size and measurements of urin...

Introduction: IgG4-related Hashimoto’s thyroiditis (HT) is a very recently reported entity, characterized by thyroid inflammation rich in IgG4-positive plasma cells associated with marked fibrosis. It may be part of the systemic IgG4-related sclerosing disease and is associated with younger age, lower female:male ratio, higher levels of thyroid autoantibodies, low echogenicity on ultrasound (US), rapid progress requiring surgery and more subclinical hypothyroidism, when c...
