Rarest type of thyroid carcinoma is
Correct Answer: Anaplastic
Description: Undifferentiated (anaplastic) carcinoma
This is one of the most aggressive malignancies in humans.
Thankfully it is rare. It may develop de novo, or present as dedifferentiation of a papillary or poorly differentiated carcinoma. The disease is characterised by rapid growth, visceral invasion and distant metastases. The surgeon’s role in this disease is crucial. Thyroid lymphoma can be incorrectly diagnosed as anaplastic cancer and so biopsy is critical. This can be done using a core or open technique.
