Poorly differentiated thyroid cancer (PDTC) lies in the intermediate zone in the thyroid carcinoma spectrum. It is the most common cause of non-ATC cancers-related mortality. We happened to encounter such a rare disease in one of our patients and are here to discuss the entire details about the course of the patient in our hospital. This was a 73-year-old female patient who was operated on for goiter and postoperative histopathology revealed poorly differentiated thyroid cancer. Though it is an important cause of mortality in 15% of cases of thyroid cancer, very little is understood about the PDTC.
