IMPRESSIVE case illustrating transformation of a Papillary Thyroid Carcinoma, Tall Cell Subtype (patient is S/P total thyroidectomy) to an Anaplastic Thyroid Carcinoma 9 years later (FNA of a Level 3 neck node). (Core bx and PAX8, focally positive in more epithelioid areas).

Are you ready for the #COTW? This case is from a 38-year-old female with a prior surgical history of a breast lumpectomy. She now presents with a lung mass. What is your diagnosis?
