A healthy 24-year-old lady was found to have a thyroid nodule. The nodule was around 1 cm in size and was reported to be mainly cystic (fluid filled). A biopsy was done and this reported that "no malignant cells” had been found.
She presented one year later for a re-evaluation. The nodule/mass had grown somewhat in size, and I was a little uncomfortable with its appearance. We decided to repeat the biopsy. The solid part of the nodule was around 50% of the total mass. This was biopsied and found to be cancerous!
The patient will be undergoing thyroid surgery, which we expect will be curative.
