Oesophageal cancer is categorised among the most fatal cancers across the world with a mortality ranking of sixth position. Chemotherapy with FOLFOX—a regimen of fluorouracil, leucovorin, and oxaliplatin—has been approved in the treatment of oesophageal cancer owing to its lower toxicity compared with the previous regimens. We report the first case of a patient with oesophageal cancer metastatic to the hyoid presenting with sudden-onset shortness of breath and anterior neck swelling secondary to treatment with FOLFOX-6. CT was notable for subglottic soft-tissue swelling and cystic necrosis of the hyoid bone tumour, and the patient subsequently required placement of a definitive airway via tracheostomy. This case illustrates the importance of anticipating the need for pre-emptive tracheostomy in patients with hyoid bone tumours receiving treatment with FOLFOX.
