Abstract:
Being described first 1912 by Hashimoto, Chronic lymphocytic thyroiditis has been most commonly diagnosed as inflammatory thyroid disease. Despite of worldwide reports about the concomitant malignancy with Hashimoto's thyroiditis, the definite incidence of coexsiting malignancy and the etiologic relationship between these different pathologic conditions remains to be brought out. Analyzing 18 cases of coexisting thyroid carcinoma among 80 cases of Hashimoto's thyroiditis, confirmed by pathologic study at Presbyterian medical center in Chonju between 1991 and 1995, the authors intended to make guideline of management for them. The results are as follows: 1. The incidence of coexisting carcinoma with HT was 18/80(22.5%). 2. The average age of patients with coexisting carcinoma was 44.1 years and all of them were female.3. Cold nodules on thyroid scan were noticed in 23 cases(22.7%) of HT and 7 cases(33.8%) of coexisting carcinoma with HT. 4. Calcified lesions on thyroid sonography were detected in 0 cases of HT and 4 cases(50%) of coexisting carcinoma. 5. The pathologic types of carcinoma were papillary(17/18, 94.4%) and follicular(1/18, 5.6%). 6. 3 cases of coexisting carcinoma had metastatic lesions on peritracheal lymph nodes and another 3 cases had on ipsilateral jugular nodes. 7. The carcinoma of smaller than 0.5cm were 7 cases, of 0.6-1.0cm were 3 cases, of 1.1-1.5cm were 5 cases, and so 15 cases(83.3%) were occult carcinoma. Only 3 cases were larger than 1.6cm. 8. Coexisting carcinoma patients with HT underwent subtotal thyroidectomy (4 cases), subtotal thyroidectomy & anterior compartment dissection (ACD, 6 cases), subtotal thyroidectomy & modified RND (2 cases), thyroid lobectomy & ACD (4 cases), thyroid lobectomy & modified RND (1 cases), or near total thyroidectomy & ACD (1 case).
