When is medullary thyroid carcinoma “medullary thyroid carcinoma”?
World Journal of Surgery, 1986AbstractMedullary 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 ...

Renal medullary carcinoma is a rare and extremely aggressive neoplasm that almost always develops in young patients with sickle cell trait. To our knowledge all cases to date have been metastatic at surgical resection. Pathological examination reveals an aggressive tumor mainly involving the renal medulla with a varied morphology.

Medullary structure of the Umbilicariaceae
The Lichenologist, 1995Abstract The medullary structure of 24 Umbilicariaceae species was studied by light microscopy. The objective was to investigate the variability of the medulla of these lichens and to assess the possible implications for thallus ecophysiology and the taxonomic relevance of the anatomy of this layer.

Histiocytic Medullary Reticulosis
Australian and New Zealand Journal of Medicine, 1975Summary: The clinical and pathological features of histiocytic medullary reticulosis (HMR) are described in five patients. Treatment by splenectomy and the MOPP routine resulted in a transient improvement in platelet and neutrophil counts and resolution of anaemia and apparent prolongation of survival in two of the five patients.The relationship of ...

Medullary thyroid carcinoma (MTC) is subdivided into sporadic (75%) and hereditary (25%) forms. Several germline mutations in the RET proto-oncogene are the source of distinct clinical phenotypes in hereditary MTC including familial MTC (FMTC) and multiple endocrine neoplasia 2A (MEN 2A) and 2B (MEN 2B).

Infarction of the Conus medullaris
European Neurology, 2008We encountered a patient with acute cauda equina syndrome. The clinical course, laboratory data and imaging study, including magnetic resonance imaging (MRI) strongly suggested that this episode was caused by a vascular disorder of the conus medullaris.

Abstract Twenty cases of medullary sponge kidney (MSK), diagnosed on the basis of urographic findings, are reported in tabular form, the pertinent literature is considered and the generally held concept of MSK as a distinct clinical and pathologic entity is critically examined. The available evidence does not support the distinctiveness of MSK. Rather,

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 ...

Computerized Medical Imaging and Graphics, 1989
Two patients developed primary medullary hemorrhages. Both patients were normotensive. They were both receiving oral anticoagulation but the coagulation studies were not excessively prolonged at the time that the hemorrhage occurred. The diagnosis of primary medullary hemorrhage was established by CT findings.

Surgical Oncology Clinics of North America, 2006
The goal in managing patients who have MTC is to detect and surgically remove disease at an early stage. Tumor marker-based biochemical screening and DNA-based genetic screening have created the opportunity for effective prophylactic surgery in patients at risk for hereditary MTC.
