title: Epithelioid hemangioendothelioma of the thyroid: a case report.
abstract: BACKGROUND
  Epithelioid hemangioendothelioma (EHE) of the thyroid is an extremely rare disease; only three cases have been reported in the English literature to date. Here, we describe a case involving a patient with thyroid EHE successfully treated with curative surgery.
  
  
  METHODS
  A 74-year-old woman presented with a right thyroid mass. The nodule was approximately 2 cm in size and was diagnosed as an indeterminate lesion by fine needle aspiration cytology. She was treated with thyroid lobectomy. The histopathological and immunohistochemical findings indicated an EHE of the thyroid. At the latest follow-up, 3 years postoperatively, the patient showed no signs of recurrence.
  
  
  CONCLUSIONS
  There is currently no standard therapy for EHE; however, our case suggests that curative resection represents an effective treatment.
