title: [Clinical characteristics of the thyroid follicular carcinoma].
abstract: BACKGROUND
  the prevalence of thyroid follicular carcinoma (TFC) is 39 % in patients with an undetermined histological diagnosis. The aim was to know the prevalence of TFC in a hospital with high population concentration.
  
  
  METHODS
  surgical reports with a final diagnosis of TFC were reviewed. The size of the tumor, age, gender, pre- and post-surgical diagnosis and comorbidities were retrieved.
  
  
  RESULTS
  a total of 35 reports with a diagnosis of TFC were found: 30 (85 %) were females with a mean age 44 ± 16.9 years. The mean age was 57 ± 6.6 in males. The diagnoses before surgery were follicular carcinoma 14 (40 %), thyroid cancer 6 (17.1 %), thyroid adenoma 4 (11.4 %), goiter 3 (8.5 %), thyroid nodule 3 (8.5 %), one papillary carcinoma (2.8 %), one thyroid neoplasm (2.8 %), one poorly differentiated adenocarcinoma (2.8 %), one well differentiated follicular adenocarcinoma (2.8 %), and one medullary thyroid cancer (2.8 %). The comorbidities found were Hashimoto disease 2 (5.6 %) and papillary contralateral carcinoma 2 patients (5.6 %).
  
  
  CONCLUSIONS
  follicular carcinomas of the thyroid of our population differ in clinical presentation compared with previous reports.
