Incidental Thyroid Carcinoma in Patients Treated Surgically for Presumably Benign Thyroid Disease

Incidental Thyroid Carcinoma (ITC) is quite high as been reported in the world's Journal. This study reviews the frequency of the ITC in patients treated surgically for otherwise benign Thyroid disease in one of the Endocrine surgery unit of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. This study was developed by the investigating the outcome of one hundred and twenty seven patient who underwent partial or total thyroidectomy for benign thyroid pathology in a single Endocrine Surgery Unit of BSMMU from January 2011 to July 2015. This observational study was done to find out the actual incidence of thyroid malignancy among the patients admitted for surgical management with thyroid pathology. All patients underwent at least FNAC and Ultrasonography of the Neck before surgery. Patients with undetermined cytology and follicular nodules were excluded from the study. Overall 19(14.96%) incidental thyroid carcinoma was recorded. Among the ITC 11(8.66%) Papillary Carcinoma, 7(5.51%) Follicular Carcinoma & 1(0.79%) is poorly differentiated carcinoma. The Overall incidence of papillary carcinoma is higher among the incidental carcinoma of Thyroid. Increased incidence associated with follicular adenoma present as an isolated thyroid nodules or multifocal lesion and should be considered malignant potential and total thyroidectomy would be the right choice as surgical management of the both cases. In case of multinodular goiter, total thyroidectomy is currently practiced in majority of the centers and our observations reinforced the attitude further.
