What are the Histological Features of Thyroid Cancer?
Thyroid cancer can be of various types, each with distinct histological features:
1. Papillary Thyroid Carcinoma: Characterized by papillary structures, nuclear grooves, and inclusions; psammoma bodies are often present. 2. Follicular Thyroid Carcinoma: Shows follicular pattern with capsular and vascular invasion. 3. Medullary Thyroid Carcinoma: Arises from parafollicular C cells, marked by amyloid deposits and calcitonin production. 4. Anaplastic Thyroid Carcinoma: Highly aggressive, showing undifferentiated cells with pleomorphism and necrosis.
