Abstract

Introduction: Anaplastic thyroid carcinoma constitutes 2-5% of all thyroid cancers. It is seen more commonly in women. In this article, we present a case of a male patient with rapidly growing anaplastic thyroid carcinoma presenting with neck pain.
Case Report: A 62-year-old male patient was admitted with neck pain and tenderness, mimicking subacute thyroiditis. Following 1 month glucocorticoid therapy, pain and tenderness of thyroid persisted and a fine needle thyroid aspiration biopsy showed undifferantiated anaplastic carcinoma of thyroid.
Conclusions: In the case of painful thyroid without responsive to glucocorticoid therapy, a diagnosis of anaplastic throid carcinoma should also be keep in mind.
