title: Hyperfuctioning insular thyroid carcinoma: A rare case report.
abstract: BACKGROUND
  Insular carcinoma of thyroid (ICT) is a rare pattern of thyroid tumor. Being hyperfunctioning makes the condition rarer. Here we reported a case of ICT associated with hyperthyroidism.
  
  
  METHODS
  A 65-year-old female presented with neck mass for 4 years. She had symptoms of thyrotoxicosis and received antithyroid treatment. She was referred for surgical management. She had multiple, non tender, mobile masses in the neck. Ultrasound showed midline multiple heterogenous mass lesions with multiple lymph nodes in right side of the neck largest one measuring 2×2cm. The patient was prepared for total thyrodectomy with radical neck dissection. The result of histopathology confirmed unifocal, poorly differentiated ICT. The post operative course was uneventful.
  
  
  CONCLUSIONS
  Insular carcinoma is a rare disease. It may present with long history of signs and symptoms of hyperthyroidism. Total thyroidectomy is the main line of treatment.
