Medullary thyroid cancer is a form of thyroid carcinoma which originates from the parafollicular cells (C cells), which produce the hormone calcitonin. [1] Medullary tumors are the third most common of all thyroid cancers and together make up about 3% of all thyroid cancer cases. [2] MTC was first characterized in 1959.
Calcitonin. Calcitonin is a 32 amino acid peptide hormone secreted by parafollicular cells (also known as C cells) of the thyroid (or endostyle) in humans and other chordates [5] in the ultimopharyngeal body. [6] It acts to reduce blood calcium (Ca 2+), opposing the effects of parathyroid hormone (PTH). [7]
Thyroid disease is a medical condition that affects the function of the thyroid gland. The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.

[69] However, in South Korea, thyroid cancer was the 5th most prevalent cancer, which accounted for 7.7% of new cancer cases in 2020.
H&E stain. Specialty. Endocrinology. Multiple endocrine neoplasia type 2B (MEN 2B) is a genetic disease that causes multiple tumors on the mouth, eyes, and endocrine glands. It is the most severe type of multiple endocrine neoplasia, [2] differentiated by the presence of benign oral and submucosal tumors in addition to endocrine malignancies.
Specialty. Oncology. Thyroid neoplasm is a neoplasm or tumor of the thyroid. It can be a benign tumor such as thyroid adenoma, [1] or it can be a malignant neoplasm (thyroid cancer), such as papillary, follicular, medullary or anaplastic thyroid cancer. [2] Most patients are 25 to 65 years of age when first diagnosed; women are more affected ...
Papillary thyroid cancer (papillary thyroid carcinoma, [1] PTC) is the most common type of thyroid cancer, [2] representing 75 percent to 85 percent of all thyroid cancer cases. [1] It occurs more frequently in women and presents in the 20–55 year age group. It is also the predominant cancer type in children with thyroid cancer, and in ...
