Hashimoto's thyroiditis: not uncommon in simple benign goiter. A review of 1102 thyroidectomies for simple benign goiter

Objective: To see the frequency of Hashimotos Thyroiditis [HT] in patients operated with the diagnosis of simple goiter

---

Study Design: A retrospective multicenter study

---

Place and duration: From 1[st] January 1999 to 31[st] March 2011 at three tertiary care hospitals

---

Methodology: All patients with simple benign goiter irrespective of age and sex are included in the study. Patients already diagnosed for hashimotos thyroiditis, recurrent goiter, abnormal thyroid hormone profile, diagnosed congenital thyroid pathology or non availability of postoperative histopathology were excluded from the study. Histopathology of all patients reviewed to see the frequency of hashimotos thyroiditis in patients operated for benign simple goiter

---

Results: Among a total of 1102 patients, 91.28% [n=1006] were female and the majority were in 5[th] decade [35.48%, n=391] of life. Histopathology review of all patients operated for benign simple goiter showed that 2.81% [n=31] were having Hashimoto's thyroiditis and majority [87.09%, n=27] were female. Hashimoto's thyroiditis were common in patients who was in the 3[rd] decade of life followed by 4[th] decade, i.e. 35.48% [n=11] and 32.26% [n=10] respectively

Conclusion: Hashimotos thyroiditis is not uncommon and due to its varied clinical presentation it should be ruled out in simple benign goiter before surgery
