Mucoepidermoid Carcinoma Of Thyroid Gland: A Rare Case Report
Abstract
Introduction: Mucoepidermoid carcinoma is a common neoplasm of the salivary gland but can also occur in other sites like oesophagus, breast, lungs, pancreas, etc .In thyroid gland it is very uncommon or rare and is said to be of low grade indolent neoplasm. In literature few cases have been reported.
Case report: 43 year old female presented with progressive midline swelling since 20 years with alteration in voice since two months. CT revealed heterogeneous enhancing lesion of 35x50x37 mm in left lobe of thyroid. FNAC revealed epithelial malignancy. Total thyroidectomy was done and specimen sent for histopathology.
Result: Microscopically the tumor showed cells arranged in follicular and trabecular pattern. These tumors cells were of columnar and mucin producing type arranged in glandular pattern. Some of the cells show squamous metaplastic changes. These glands or follicles lack colloid. Final diagnosis of mucoepidermoid carcinoma of thyroid was given.
Conclusion: Mucoepidermoid Carcinomaof thyroid is low grade neoplasm which extends into  ajjacent tissue by local infiltration and unlikely to metastasize, hence progress is good. It can also have agressive behaviour and hence a through search to be done histologically and also rule out other metastatic lesions.
