You are surprised to see that it is Catherine, your longstanding neighbor. After a few pleasantries, you ask her what brought her in today.\n\nShe hands over a referral letter. In this, her primary care physician asks you to look into a mass he discovered in her neck, during a routine office visit.\n\nYou note that she is 46 years old and completely asymptomatic. Her medical history is unremarkable, and she is not on any medications.\n"}]}

All vitals are stable.\n\nYou proceed to palpate a firm non-tender lump in front of her trachea, which is around 3 cm in diameter. The lump moves with swallowing and is not fixed to the adjacent tissues.\n\nThere is no cervical, supraclavicular, or axillary lymphadenopathy, and the remainder of the examination reveals no abnormal findings.\n\nYou order a thyroid profile and ultrasound scan of the neck and ask Catherine to drop in later, once the results are available.\n"}]}
