• squamous metaplasia in the thyroid gland
  30 May 2016

  thyroid squamous cell metaplasia; thyroid squamous metaplasia
  Squamous metaplasia (SM) occurs in a variety of thyroid conditions, both neoplastic and non-neoplastic.
  In a small subset of benign thyroid lesions, SM can create a diagnostic pitfall by mimicking a malignant process.
  SM of the thyroid represents an important diagnostic pitfall for the cytopathologist, and should be included in the differential diagnosis of thyroid nodules, particularly those with potentially benign cystic (...)
