title: [Nodular or pseudo-nodular Hashimoto thyroiditis. Value of cytologic examination].
abstract: OBJECTIVE
  Nodular or pseudo-nodular aspects of Hashimoto's thyroiditis raise the problem of the association with a differentiated carcinoma or a non Hodgkin's lymphoma.
  
  
  METHODS
  We looked for patients needing surgery in 165 cases of Hashimoto's thyroiditis. For this purpose, we used fine needle aspiration cytology.
  
  
  RESULTS
  We found a differentiated carcinoma in 4% of cases and a non Hodgkin's lymphoma in 1% of cases.
  
  
  CONCLUSIONS
  In nodular or pseudo-nodular aspects of Hashimoto's thyroiditis, fine needle aspiration cytology is helpful for the nodule diagnosis and for the selection of suspicious nodules only to be referred to surgery.
