A 42-year-old woman undergoes a total thyroidectomy for a multinodular goitre. On the first postoperative day she notices that her voice is weak and has a new high-pitched quality when attempting to sing or speak on higher notes. On laryngoscopic exam the vocal cord mobility is preserved but the patient cannot tense the ipsilateral vocal cord. Which nerve was most likely injured during surgery?

A 24-year-old woman presents with a 1.5 cm, painless, firm, mobile, well-circumscribed breast lump discovered incidentally. It is non-tender, rubbery, and moves freely under the skin; ultrasound shows a homogeneous, oval lesion with smooth margins. Which is the most likely diagnosis?
