Cancers derived from the follicular epithelium (papillary, follicular, and poorly differentiated
(anaplastic) cancers) comprise about 60–95% of all thyroid carcinomas. The rest are, in …

This paper reviews both clinicopathologic and biological factors in differentiated thyroid
carcinoma of follicular and C-cell derivation. The value of specific histological parameters …

Tumors of the thyroid are subclassified based on the cell of origin and commonly include
follicular-derived tumors and C-cell-derived tumors. The most common follicular-derived …

Thyroid-specific malignant tumors are derived from follicle cells (papillary and follicular
carcinoma), and from parafollicular, calcitonin-producing C-cells (medullary carcinoma). The …

Forty‐four follicular thyroid neoplasms followed for a minimum of 10 years are presented.
The cases were divided into four categories: follicular adenoma (19 cases), encapsulated …

The spectrum of human thyroid cancer includes both indolent differentiated neoplasms and
highly virulent, rapidly fatal anaplastic carcinoma. The majority of thyroid carcinomas (about …

Thyroid neoplasms are classified into three major categories: epithelial, nonepithelial, and
secondary. Most primary epithelial tumors of thyroid are derived from follicular cells. These …

Divergent endocrine-neuroendocrine differentiation in thyroid carcinoma occurs in mixed
medullary-follicular carcinomas (MMFC). Less than 40 cases of MMFC have been reported …

The recognition of the pathological features of medullary thyroid carcinoma (MTC) by Horn1
and Hazzard et al2 in the 1950s and the demonstration that it derived from the calcitonin …

This paper constitutes a brief review of recent developments related to medullary carcinoma
of the thyroid gland. The following topics are discussed: definition; pathologic variants; …
