Explain of Endocrine Pathology

17.Thyroid, papillary carcinoma, gross

Sectioning through a lobe of excised thyroid gland reveals papillary carcinoma. This neoplasm can be multifocal, as seen here, because of the propensity to invade lymphatics within thyroid, and lymph node metastases are common. The larger mass is cystic and contains papillary excresences. These tumors most often arise in middle-aged females.
