Extrathyroidal Calcitonin Secreting Tumors: Pancreatic Neuroendocrine Tumors in Patients With Multinodular Goiter
Calcitonin is the hallmark of medullary thyroid carcinoma. However, extrathyroidal neuroendocrine tumors can also release calcitonin.We report 2 cases of calcitonin-secreting pancreatic tumors found in asymptomatic patients with thyroid nodules referred to our center within 11 months.Case 1: A man initially referred for thyroid nodule characterization was found to have hypercalcitoninemia (>200...
متن کاملEarly spontaneous deficiency of calcitonin renal binding sites in rats with a high incidence of calcitonin-secreting tumors (WAG/Rij).
Old rats of the WAG/Rij strain have a high incidence (50%) of medullary thyroid carcinoma, a calcitonin (CT)-secreting tumor. We have characterized and quantified the topographical distribution of [125I]salmon calcitonin (sCT) binding sites in the kidneys of this strain, as compared to Wistar CF rats (2% incidence of spontaneous medullary thyroid carcinoma). We report here that, up to 15 days o...
متن کاملAndrogen Secreting Ovarian Tumors
Other rare ovarian causes of hyperandrogenism include gynandroblastoma, gonadoblastoma, ovarian carcinoid, surface epithelial tumors (Brenner tumor) and metastatic tumors [5]. These tumors are rare representing only 10% of all ovarian tumors. Tumoral cause of hyperandrogenism is suspected when the serum testosterone levels are significantly elevated (>200 ng/ml), rapidly progressive symptoms of...
متن کاملCalcitonin-Secreting Neuroendocrine Carcinoma of Larynx with Metastasis to Thyroid
Primary neuroendocrine tumors of the larynx are rare, with moderately differentiated neuroendocrine carcinoma (MDNC) being the most frequent histologic type. We report a MDNC in a 57-year-old gentleman with an enlarging right-sided neck mass. Flexible fiberoptic exam revealed a right arytenoid lesion. Histology from excisional biopsy was concerning for medullary thyroid carcinoma (MTC) versus N...
متن کاملAsymptomatic calcitonin-secreting tumor of the pancreas. A case report.
CONTEXT Pancreatic endocrine tumors are unusual tumors arising from cells belonging generically to the amine precursor uptake and decarboxylation system. CASE REPORT We present a case of a calcitonin-secreting pancreatic endocrine tumor in a 59-year-old male who presented at our Center with elevated calcitonin values. The patient was asymptomatic. Further investigation revealed a tumor, 80 mm...
