Mucinous thyroid cancer is a rare type of thyroid cancer that arises from the follicular cells of the thyroid gland. It is characterized by the presence of abundant mucin, which is a complex mixture of glycoproteins and carbohydrates, in the tumor cells. Mucinous thyroid cancer is considered an aggressive subtype of thyroid cancer and has a poorer prognosis than other types of thyroid cancer.
The initial laboratory investigations, including thyroid function tests, were within normal limits. Ultrasound of the neck revealed a hypoechoic mass in the left lobe of the thyroid gland measuring 4 cm in diameter with irregular margins. Fine needle aspiration cytology (FNAC) of the mass was inconclusive.
Mucinous thyroid cancer is a rare and aggressive subtype of thyroid cancer that is characterized by the presence of abundant mucin in the tumor cells. It has a poor prognosis and is usually diagnosed at an advanced stage. The treatment of mucinous thyroid cancer typically involves surgery, radiotherapy, and chemotherapy
