When is medullary thyroid carcinoma “medullary thyroid carcinoma”?

World Journal of Surgery, 1986
AbstractMedullary thyroid carcinoma (MTC) is thought to develop from the parafollicular or C cells within the thyroid gland and, therefore, should not take up radioactive iodine. Recently, however,131I uptake has been reported in metastases of “medullary carcinoma” and, consequently, some authors have suggested that these tumors can be treated with ...

Medullary carcinoma of the thyroid

The Laryngoscope, 1976
AbstractMedullary carcinoma is an unusual malignant neoplasm. The cell of origin is considered to be the C‐cell which is derived from the ultimo‐branchial body and neural crest. The tumor is solid and has characteristic amyloid in the stroma. The lesion usually presents as a neck mass, and multicentricity is not unusual.

Medullary carcinoma of the breast

Cancer Treatment Reviews, 1988
Medullary carcinoma of the breast (MC) was primarily characterized histopathologically in the late 1940s. Until then, the word 'medullary'-when applied to mammary car- cinoma-had been used with different meaning by various writers. As early as 1945, Geschichter (16) mentioned in a textbook of pathology the 'so-called medullary cancers' under a heading ...

Medullary carcinoma of the thyroid

World Journal of Surgery, 1981
AbstractMedullary carcinoma of the thyroid (MCT) is a rare tumor which, since its identification by Hazard et al. [2] in 1959, has attracted interest for 2 reasons. First, the secretion of the tumor marker, thyrocalcitonin, provides a means of making the diagnosis of MCT before the tumor is clinically evident.

Medullary thyroid carcinoma

Current Treatment Options in Oncology, 2003
Medullary thyroid carcinoma (MTC) is a neuroendocrine malignancy that occurs in hereditary (25%) and sporadic (75%) clinical settings. MTC is present in all patients with the multiple endocrine neoplasia type 2 syndromes. MTCs produce calcitonin, the measurement of which can indicate the presence of tumors in people who are at risk and the ...

Medullary Thyroid Carcinoma

Hematology/Oncology Clinics of North America, 2007
Medullary thyroid carcinoma is a neuroendocrine tumor derived from the C cells of the thyroid gland and accounts for approximately 5% of all thyroid carcinomas. Approximately 30% of the cases are associated with an autosomal dominant syndrome called multiple endocrine neoplasia type 2, and the identification of these individuals is important because ...

Medullary Carcinoma of the Thyroid

Archives of Otolaryngology - Head and Neck Surgery, 1983
Medullary cancer of the thyroid is rare but of unusual biologic interest. It originates in the thyroid parafollicular or C cells that are of neural crest origin and that secrete calcitonin. Calcitonin measurements, particularly after pentagastrim administration, are useful in detecting the tumor and following its progression.
