title: Thyroid MALT lymphoma in patients with a compressive goiter.
abstract: BACKGROUND
  Mucosa-associated lymphoid tissue (MALT) lymphomas account for less than 1% of all primary thyroid malignancies. They typically arise as neoplastic transformations within areas of autoimmune thyroiditis. Although they tend to have an indolent course, these lymphomas present a diagnostic challenge requiring a high level of suspicion in patients at increased risk of development.
  
  
  METHODS
  We retrospectively reviewed 3 cases of primary MALT thyroid lymphoma discovered in patients with a compressive goiter. This represents the experience at a single institution from 1996 to 2005. Hospital and clinic records were reviewed to identify the workup, treatment, and outcome.
  
  
  RESULTS
  One of 3 patients underwent preoperative fine-needle aspiration (FNA). All patients underwent total thyroidectomy to relieve compressive symptoms, and the final pathology revealed MALT lymphoma. Two patients subsequently underwent radiation therapy. All patients are alive without evidence of disease recurrence.
  
  
  CONCLUSIONS
  These cases are notable for the unexpected presentation of MALT lymphoma within a compressive goiter.
