title: Hypertensive crisis in a patient with thyroid cancer.
abstract: Phaeochromocytomas may be discovered incidentally when patients present with hypertensive crisis during general anaesthesia. A 49-year-old man underwent thyroidectomy 25 years ago and was diagnosed to have spindle cell carcinoma of the thyroid. He presented with recent onset of hoarseness of voice and was found to have a vocal cord nodule. He developed a hypertensive crisis during surgery. He was subsequently evaluated and found to have bilateral phaeochromocytoma. Further evaluation revealed a RET proto-oncogene mutation at codon 634 consistent with multiple endocrine neoplasia (MEN)-2A.
