Inactivating mutations of the multiple endocrine neoplasia 1 (MEN1) gene cause MEN1 syndrome, characterized by primary hyperparathyroidism (pHPT), and parathyroid and gastro-entero-pancreatic pituitary tumors. At present, only 14 cases of malignant parathyroid tumor have been associated with the syndrome, with 6 cases carrying an inactivating mutation of the MEN1 gene. The present study present...
minimally invasive radio-guided surgery for hyperparathyroidism: an experience with tc-99m sestamibi
introduction: radio-guided parathyroid surgery along with other minimally invasive surgeries constitutes the main surgical treatment procedures for different kinds of hyperparathyroidism. in this article we have reported our experience of radio-guided parathyroid surgery using tc-99m sestamibi. methods: ten patients with hyperparathyroidism included in our study. twenty mci of tc-99m sestamibi...
he observation of ectopic synthesis and secretion polypeptide hormones by nonendo, tumors has been reported with increasing frequency in the past decade. Carcinomas of the lung have been particularly versatile in this regard. Reports have included corticotropin ( adrenocorticotropic hormone) and vasopressin found in some oat-cell carcinomas, gonadotropins predominantly in large-cell carcinomas,...
A 17-year-old boy with hyperparathyroidism exhibited a large cyst in the left hemi-thorax on his chest X-ray. The cyst was identified as a hydatid cyst. He was referred for biphasic methoxy isobutyl isonitrile (MIBI) parathyroid scan. A discrete ectopic parathyroid was detected in the left upper mediastinum in addition to accumulation of the MIBI tracer in the cyst wall. Using radio-guided occu...
A 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with lOOmCi of iodine-131 and negative whole body scans was referred for follow up study. Tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. The patient was operated, the parathyroid adenoma was removed. ...
Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...
parathyroid adenomas, or hyperplasia may be present in patients with hypercalcemia. treatment is by surgical excision, but about 10% of the lesions may be in ectopic locations. pre-operative localization of the lesions with non-lvasive imaging, using radionuclides, ultrasound, ct, or mr], may simplify surgery, and reduce patient morbidity. however, the reports of the accuracy of the currently a...
case presentation: this case illustrated the development of secondary and subsequently tertiary hyperparathyroidism in a 66-year-old man with a history of chronic renal failure. the patient was managed surgically by parathyroid autotransplantation and serial explantation. discussion: refractory hypercalcemia due to autonomous parathyroid tissue following parathyroidectomy can be managed with gr...
We report a patient with a biochemically and radiologically confirmed parathyroid adenoma, which underwent spontaneous resolution by necrosis. The patient was followed-up over the subsequent two years during which time the tumour and hypercalcaemia recurred. Sequential radiological and biochemical changes at the time of diagnosis, spontaneous necrosis and recurrence are documented fully.
