[Anaplastic carcinoma of the thyroid in a young man. A report of a case]

Anaplastic thyroid carcinoma is a tumor that has a very ominous prognosis, and is characteristic of people older than 60 years. Generally occurs as a neck lump of rapid growth rate, arousing compressive symptoms on nearby structures. We report the case of a 29-year-old patient who presented an anaplastic thyroid carcinoma. He was treated with surgery, chemotherapy and radiotherapy, but died 10 months after being diagnosed.
