Solitary nodules of the thyroid are uncommon. Approximately 15% may be associated with underlying thyroid cancer. Careful evaluation is required. Potential causes of a solitary thyroid nodule include:

  • benign adenoma;
  • thyroglossal cyst;
  • ectopic, normal thyroid tissue;
  • single median thyroid gland;
  • thyroid cyst or abscess;
  • thyroid carcinoma.

The investigation should include a radioisotope (99mTc) scan. Cold nodules or nodules that feel hard on palpation, or are rapidly growing should raise suspicion of thyroid cancer. Biopsy and surgical excision are indicated.
