If this association predisposes to larger, multifocal or more aggressive cancer (especially in Graves’ disease) is a matter of debate. We describe the clinical and hystopathological aspects and evolution in two patients with hyperthyroidism and thyroid cancer.Patient 1, a 42-year-old woman, was diagnosed in 2008 with Graves’ dis...

Introduction: Differentiated thyroid carcinoma is a rare entity in pediatric population, with particularities in diagnosis, management and outcomes.Methods, aim: Retrospective noninterventional study describing clinical presentation and outcomes of children with DTC.Results: Between 2011 and 2017 54 children and adolescents aged 7.8–18 years (mean age at diagnoses 14.4 years) with DTC were diagnosed/followed up in our Institut...

Introduction: In human cancer cells DNMTs are responsible for both de novo and maintenance methylation of tumor suppressor genes. Many studies have analyzed the relationship between the altered expression of DNMT1 and DNA methylation in cancer.Aim: To analyze DNMT1 expression in thyroid papillary carcinoma.Design: 49 patients aged 10–82 years hospitalized for thyroidectomy were included between January 2013 and July 2...

Introduction: HOXB4 functions as a transcription factor involved in cell differentiation during embryogenesis and plays a role in apoptosis.Aim: This study analyzed HOXB4 methylation status in thyroid papillary carcinoma.Method: 54 patients aged 10–82 years hospitalized for thyroidectomy were included between January 2013 and July 2013. The inclusion criterion was patients with thyroid nodules with indication for surgery and t...
