Follicular lesion |
Follicular adenoma, adenomatoid nodules, and lymphocyticthyroiditis Lack of capsular or vascular invasion. Resection is for definitive diagnosis and symptommanagement. Hemithyroidectomy, no further intervention |
|
|
Papillary thyroid carcinoma (PTC) |
85 % of differentiated thyroid cancers Need total thyroidectomy (except encapsulated follicular variant PTC, only lobectomy is needed) May choose to do central neck dissection (CND) – especially for larger tumors |
|
|
Follicular carcinoma |
– 10 % of differentiated thyroid cancers – Includes Hurthle cell carcinoma as an entity – Need total thyroidectomy – May choose to do central neck dissection – again, especially for larger tumors |
|
|
Medullary carcinoma |
– Mainstay of treatment is surgery. – More aggressive disease. – Total thyroidectomy and central neck lymph node dissection are imperative. – Consider lateral neck lymph node dissection if clinical disease is present |
|
|
Lymphoma |
– Large, rapidly expanding neck mass. – Portion of gland sent rather than whole gland. – Surgical resection not indicated. Attain stable airway. – Very radio-responsive, although chemotherapy is often used. |
|
|
Anaplastic thyroid cancer |
– Large, rapidly expanding neck mass. – Portion of gland sent rather than whole gland. – Invades surrounding structures. – Surgical resection not indicated. Attain stable airway. – Treatment is palliative or clinical trial |
