Abstract

We present the case of a female patient in her late 70s, diagnosed with widely invasive oncocytic cell carcinoma, with extrathyroidal extension, infiltration into the extrathyroidal muscle, involvement of the sternohyoid muscle and infiltration into the external muscle fibres of the oesophagus. Over the following year, metastases were documented in the lungs, bones and brain. Additionally, there was progression of the locally advanced lesion involving the airway and upper gastrointestinal tract. After considering iodine refractoriness, treatment with sorafenib was initiated. Notably, regression of the locoregional lesion at the cervical level was observed following treatment with the multikinase inhibitor.
