ObjectiveTo investigate the condition of neck lymph node metastasis and related factors in thyroiditis coexisting thyroid cancer, and make clear the indication of neck lymph node dissection. MethodsA retrospective cohort study was conducted with the clinical data of 147 patients with thyroiditis coexisting thyroid cancer who underwent radical resection of thyroid cancer (total thyroidectomy or subtotal thyroidectomy) and neck lymph node dissection, including age, gender, tumor size, number of focuses, and lymph node metastasis. Results Among 147 patients, 65 patients with neck lymph node metastasis (44.22%), central cervical lymph node metastasis rate was 36.05% （53/147）， which was higher than that of lateral lymph node metastasis rate (20.41%, 30/147), Plt;0.05. Neck lymph node metastasis rate was correlated with patient’s gender and tumor size （Plt;0.05）, while it was not correlated with patient’s age and number of focuses (Pgt;0.05). ConclusionCentral neck lymph node metastasis rate is higher in patients with thyroiditis coexisting thyroid cancer, then routine prophylactic central neck lymph node dissection is significant. Patient’s gender and tumor size are correlated with neck lymph node metastasis. When tumor is larger or in male, ipsilateral lymph node dissection should be considered to done.
Objective To sum up experiences in diagnosis and treatment for Hashimoto′s disease (HD). Methods Clinical records of 78 patients who underwent operations and were diagnosed as Hashimoto′s disease by histologic examination in our hospital from Jan. 1988 to Dec. 1998 were analyzed. Results Seventy females and 8 males, aged 9 to 70 years (average of 41.6 years). HD was coexistent with 10.3% of thyroid gland malignant tumor, 23.1% of adenoma and 30.8% of other thhroid gland diseases. The misdiagnosis rate was 35.9% and missed diagnosis rate was 46.2%. The clinical feature of HD and most common cause of misdiagnosis and missed diagnosis have been discussed. Conclusion It is emphasized that patients with diffuse goiter, palpable nodules, lighty color on scintillation scintigraphy, elevation of antimicosomiaux and antithyroglobuline but no finding on Bus should be highly suspected of having Hashimoto′s disease.
ObjectiveTo summarize and analyze the clinical characteristics of patients with thyroiditis who would be misdiagnosed with thyroid tumor easily. MethodThe clinical data of 19 patients with thyroiditis who were misdiag-nosed with thyroid tumor in our department from 2009 to 2012 were analyzed retrospectively. ResultsAll of 19 patients underwent surgery, among which 8 cases were diagnosed with chronic lymphocytic thyroiditis after operation, 10 cases diagnosed with subacute thyroiditis, and 1 case diagnosed with suppurative thyroiditis.Different surgery program such as the biopsy or wedge resection was adopted to the subacute thyroiditis and the chronic lymphocytic thyroiditis respec-tively. ConclusionSometimes, it is very difficult to distinguish atypical thyroiditis from thyroid tumor so that we must pay attention to the patients who had nontumorous characteristics in order to decrease the misdiagnosis.
