Match the following thyroid nodule presentations and cytology findings with the most appropriate initial surgical or medical management.

  • A 45-year-old woman with a 4.5-cm solid thyroid nodule. Cytology shows papillary thyroid carcinoma. Ultrasound demonstrates no suspicious cervical lymph nodes.Total thyroidectomy
  • A 40-year-old man with a 1.5-cm thyroid nodule. Cytology shows medullary thyroid carcinoma. Serum basal calcitonin is markedly elevated.Total thyroidectomy with prophylactic central compartment neck dissection
  • A 32-year-old woman with a 2.5-cm thyroid nodule. TSH is normal. Cytology shows a follicular neoplasm. Molecular testing is not available.Diagnostic thyroid lobectomy
  • A 50-year-old woman with a 1.2-cm thyroid nodule. Cytology shows a benign colloid nodule. She is asymptomatic and euthyroid.Observation with routine ultrasound surveillance

Cevap

The correct matches pair papillary thyroid carcinoma > 4 cm with total thyroidectomy, medullary carcinoma with total thyroidectomy plus central neck dissection, follicular neoplasm with diagnostic lobectomy, and benign nodules with observation.
Each nodule requires a specific, distinct management strategy: PTC > 4 cm requires total thyroidectomy; medullary carcinoma requires total thyroidectomy plus central neck dissection due to aggressive lymphatic spread; follicular neoplasms require lobectomy to assess for capsular/vascular invasion; and asymptomatic benign nodules require observation.

Adım Adım Çözüm

1
Evaluate the management for the 4.5-cm papillary thyroid carcinoma.
Matches with 'Total thyroidectomy'.
Tumor size > 4 cm warrants a total thyroidectomy, but lacking clinical nodal involvement, a prophylactic central neck dissection is unnecessary.
2
Evaluate the management for medullary thyroid carcinoma.
Matches with 'Total thyroidectomy with prophylactic central compartment neck dissection'.
Medullary thyroid carcinoma has high rates of early lymphatic spread; standard of care includes prophylactic central neck dissection.
3
Evaluate the management for a follicular neoplasm without available molecular testing.
Matches with 'Diagnostic thyroid lobectomy'.
Cytology cannot distinguish a benign follicular adenoma from a malignant follicular carcinoma; histological evaluation of the capsule and vessels is required via lobectomy.
4
Evaluate the management for an asymptomatic benign colloid nodule.
Matches with 'Observation with routine ultrasound surveillance'.
Benign, asymptomatic nodules do not require surgery and are managed conservatively.

Surgical management of thyroid nodules depends heavily on the specific cytological diagnosis from fine-needle aspiration, tumor size, and histological subtype.
