Schwannoma of thyroid bed. A case report and considerations on interdisciplinary collaboration

Schwannoma of the thyroid bed is extremely rare, but is known to simulate a thyroid nodule. A retrospective review is reported of a 64-year-old female patient with a thyroid nodule who had been submitted to pre-operative fine-needle aspiration biopsy, judged inadequate, following which total thyroidectomy was performed. On histological examination, the nodule (in the thyroid bed) was found to be a schwannoma. This case report stresses the importance of interdisciplinary collaboration. Better co-operation between surgeon, pathologist and radiologist may have led to correct pre-operative diagnosis with sparing of at least half the thyroid.
