Abstract

Introduction: The coexistence of Hashimoto thyroiditis with welll differentiated

thyroid carcinoma (DTC) has been discussed as far as the follow-up and prognosis of
patients with chronic autoimmune thyroiditis (CAT) are concerned. The aim of our

study was to find the coincident appearance of the two disorders in histologic
specimens from patients who underwent total thyreoidectomy.

Material-Methodology: Between 2005-2010 228 patients (182 women/46 men) were
operated with total thyroidectomy in our clinic. The surgical specimens were studied
in the Pathology Department of our hospital.

Results: In 228 surgical specimens thyroid cancer was found in 33 (14.5%), from
them 31 were DTC (13.6%),while elements of chronic lymphocytic thyroiditis were

found in 56 (24.6%).Coexistence of Hashimoto and DTC was detected in 6 patients
(19.3% of the DTC diagnosed patients, females/males 5/1). In the population of

patients with autoimmune thyroiditis the cancer prevalence was 10.7%. There was no
statistically significant difference as far as the age is concerned (P=0.677).

Conclusion: Further analytical clinical studies are required in order to establish a

possible association between Hashimoto thvroiditis and DTC.Our results show that a

Abstract

Introduction: The effect of hyperthyroidism on the development of differentiated

thyroid cancer (DTC) has been controversial in the international bibliography. The
aim of our study was to find the possibility of thyroid cancer appearance in patients

with hyperthyroidism who underwent total thyroidectomy in comparison with patients
without thyroid hyperfunction.
