We briefly review the surgical approaches to medullary thyroid carcinoma associated with multiple endocrine neoplasia type 2 (medullary thyroid carcinoma/multiple endocrine neoplasia type 2). The recommended surgical approaches are usually based on the age of the affected carrier/patient, tumor staging and the specific rearranged during transfection codon mutation. We have focused mainly on you...

The pathological features of 67 cases of medullary carcinoma of the thyroid were studied, and when possible the case histories were reviewed. The typical tumour is sharply demarcated but not encapsulated, is composed of sheets of cells having eosinophilic granular cytoplasm, with the deposition of amyloid in the stroma. We would stress the frequency of binucleate cells, the scarcity of mitoses,...

Cutaneous metastases from thyroid carcinoma are rare. This report describes four cases of thyroid carcinoma metastatic to the skin. Two cases were medullary carcinoma and two were papillary thyroid carcinoma. In two cases, skin metastases were the presenting feature of the underlying thyroid carcinoma. Examination of the skin lesions by conventional light microscopy suggested the possibility of...

We report a rare case of asymptomatic adrenal medullary hyperplasia detected by chance with intraoperative hypertension during surgery for ipsilateral renal cell carcinoma. A 41-year-old male visited our hospital with a complaint of left flank pain. He had normal blood pressure and plasma catecholamine level was within normal limits. Ultrasonogram and CT scan revealed a left renal tumor but did...

Medullary thyroid carcinomas (MTC) constitute about 5 to 7 % of thyroid neoplasms. They originate from parafollicular C-cells which can secrete adrenocorticotropic hormone (ACTH) and/or corticotropin-releasing factor (CRF) in abnormally high concentrations, potentially causing paraneoplastic Cushing's Syndrome (CS). We report on a 42-year-old male patient with a ten year history of metastatic m...

Medullary thyroid carcinoma is a rare malignancy that arises from calcitonin-producing C-cells and frequently metastasizes to lymph nodes in the neck. Distant metastases may involve bone, lung, and liver. The infrequent number of cases limits the clinical nature and ability to optimize diagnostic tools. Here, we present a case of a micronodular radiographic pattern in metastatic medullary thyro...

This 54-year-old patient with a breast carcinoma of one year's evolution presented a progressive paraparesis and sphincter disregulation of a week evolution; MRI image showed a tumor in the medullary conus. She improved after removal of the conus mass. The histologic diagnosis was metastasis of adenocarcinoma. Metastasis at this level is infrequent and represents less than 1% of all spinal meta...

Introduction: Breast cancer is one of the most common malignant tumors and leading causes related death amongst females worldwide. The clinical significance molecular classification carcinoma breast remains to be established. Molecular subtyping using immunohistochemistry can provide additional prognostic predictive information. Aim objectives: To identify morphological variants determine vario...
