  • Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparathyroidism present with kidney stones or isolated hypercalcemia. However, nearly one third of patients are asymptomatic and hypercalcemia is found incidentally. Skeletal involvement such as generalized osteopenia, bone resorption, bone cysts and Brown tumors are seen on the late phase of hyperparathyroidism. The symptoms include axial pain, radiculopathy, myelopathy and myeloradiculopathy according to their locations. Plasmocytoma, lymphoma, giant cell tumors and metastates should be ruled out in the differential diagnosis of Brown tumors. Treatment of Brown tumors involve both the management of hyperparathyroidism and neural decompression. The authors report a very rare spinal Brown tumor case, arisen as the initial manifestation of primary hyperparathyroidism that leads to acute paraparesis.

  • The relationship between acute pancreatitis and hyperparathyroidism has been described extensively in the past. Despite the rarity, the clinical progression of pancreatitis associated with hyperparathyroidism has been known to be so rapid and severe that it may cause death. When, furthermore, the pancreatitis is caused by hyperparathyroidism, the recovery from disease can be hardly expected unless the hyperparathyroidism is corrected. We present a case of acute pancreatitis in a 68-year-old man that have been caused by primary hyperparathyroidism. The clues of hyperparathyrodism were hypercalcemia and elevated parathyroid hormone, but he showed subtle or negative symptoms of hypercalcemia. After the excision of parathyroid adenoma, serum calcium level returned to normal and the symptoms and function of pancreas were recovered.

  • The parathyroid gland is probably the simplest endocrine organ in the body. The only cells of clinical significance are the parathyroid or chief cells. The primary signal that these cells listen to is calcium. Primary hyperparathyroidism is due to a parathyroid adenoma. The most common cause of hypercalcemia in veterinary medicine is hypercalcemia of malignancy associated with variety of neoplasms. Secondary hyperparathyroidism is due to a disease process, most commonly associated with renal and nutritional hyperparathyroidism. Primary and secondary hyperparathyroidism are markedly different in their clinical, laboratory, and pathogenic mechanism.

  • The parathyroid adenoma is the most common cause of the primary hyperparathyroidism. The characteristic of primary hyperparathyroidism is hypercalcemia and high value of serum parathyroid hormone. The primary hyperparathyroidism with parathyroid adenoma is treated by excision of parathyroid gland involved. Especially, parathyroid storm in patients with primary hyperparathyroidism is more prevalent than commonly appreciated. The symptoms and signs of the syndrome are not only due to the hypercalcemia, but also to the toxic effects of the parathyroid hormone. Its wide, but nonspecific clinical presentations make it easily confused with other cardiovascular or renal diseases. The mortality rate in untreated cases of parathyroid storm is essentially 40%. A 33 year old woman with primary hyperparathyroidism was found to have a left lower parathyroid adenoma, presented with hypercalcemic crisis. Initially, good responsiveness to a saline infusion, furosemide administration was noted. Unfortunately, she became consciousness disturbance after fine-needle aspiration of the parathyroid tumor. The recurrent storm was refractory to medical therapy, but was treated succesfully by emergent surgical removal tumor revealed a parathyroid adenoma with parathyroid hormone. Hypercalcemia was alleviated postoperatively. These observations corroborated a functioning parathyroid adenoma.

  • Mucolipidosis (ML) is a kind of skeletal dysplasia. Characteristic X-ray findings of the bone may contribute to the early diagnosis and treatment of ML II/III. Skeletal radiographs show distinctive patterns at different ages: neonatal hyperparathyroidism, osteodystrophy (similar to chronic osteitis fibrosa cystica), and dysostosis multiplex. Patients with ML II/III show a mixture of osteodystrophic bone changes and atypical changes of dysostosis multiplex: proximal pointing of the metacarpals in the wrist, dysplastic changes in the lower third of the ilia, marked broadening of the ribs becoming oar-shaped, and beaking of the lower thoracic and lumbar vertebrae. In ML II, the osteodystrophy has clinical and radiographic features of neonatal hyperparathyroidism. In some neonatal subjects, chemical hyperparathyroidism is also demonstrated. After transient hyperparathyroidism in newborns, the progressive osteitis fibrosa cystica develops from 3-6 months of age. Patients with ML III show prominent skeletal involvement, particularly the destruction of vertebral bodies and the femoral heads. Intravenous pamidronate treatment is well tolerated, and it can produce clinical effects, with a reduction in bone pain and improvements in mobility in patients with ML III. In this review, the skeletal manifestations of ML II and III are investigated.

  • Nutritional secondary hyperparathyroidism in a seven-month old male kitten showing signs of paraparesis (ataxia, dragging the pelvic limbs), abdominal distention, aconuresis was diagnosed with clinical signs, radiographs and serum biochemical tests. In radiographs, bones were abnormally radiolucent and cortices were thin. Serum biochemical tests were performed, but had normal values. The treatment was directed at the suspected dietary calcium and phosphorus imbalance. Oral calcium supplement and a commercial cat food were introduced. On clinical evaluation 3 months later, this case showed no clinical signs.

  • Primary hyperparathyroidism (PHP) is a disease in which excessive amounts of parathyroid hormone (PTH) are secreted and calcium levels in the blood increase. Hypercalcemia caused by PHP has a major influence on the peripheral nervous system and produces symptoms such as muscle cramps, paresthesia, and proximal muscle weakness. Here we report a rare case of sensory-dominant polyneuropathy caused by PHP, which improved after surgery.

  • Primary hyperparathyroidism is rare disease entity which secretes parathyroid hormone in excessively resulting in hypercalcemia. It involves skeletal system, urinary tract, gastrointestinal tract, and central nervous system. Recently the determination of the serum calcium and parathyroid hormone level has become a routine laboratory test and the localization of involved gland by neck ultrasonogram and parathyroid gland substraction scan has reduced operative complications. For the purpose of improvement of diagnosis and treatment, the authors analyzed the clinical characteristics of 6 cases of primary hyperparathyroidism(adenoma 5 cases, carcinoma 1 case) during 10 years and report with literatures.

  • Primary hryperparathyroidism is a relatively rare disease entity in Korea. It's characterized by severe skeletal and renal changes due to hypersecretion of parathyroid hormone, and rarely shows peptic ulceration, hypertension, pancreatitis and impaired mentality. Recently the determination of the serum calcium level has become a routine laboratory test and the awareness of primary hyperparathyroidism has been incerased, the disease is being diagnosed with increasing frequency. Primary hyperparathyroidism is most commonly caused by parathyroid adenoma and rarely hyperplasia, cancer of parathyroid glands. The authors operated sucessfully a case of primary parathyroid adenoma by diagnosed by nuclear medical diagnostic work-up. The patient had anterior neck mass(soft, non tender nodule) on physical examination, multiple goiter on thyroid ultrasonogram and scan. The parathyroid lesion was difficult to find preoperatively.

  • The brown tumors develop in bone and it develop on various area which in clavicle, rib bone, cervical bone, iliac bone etc. The development on the maxillofacial region is rare, relatively more develop on the mandible. The brown tumor directly develop by the dysfunction of calcium metabolism according to hyperparathyroidism and differential diagnosis with other bone lesion should be difficult if it would diagnose by only radiographic features. The histological feature is that proliferation of spindle cells with extravasated blood and haphazardly arranged, variably sized, multinucleated giant cell is seen. The brown tumor is firm diagnosed by physical examination, because of these histological feature show similar with other giant cell lesions(giant cell granuloma, aneurysmal bone cyst, cherubism). The brown tumors have been described as resulting from an imbalance of osteoclastic and osteoblastic activity. It result in bone resorption and fibrous replacement of the bone. So these lesions represent the terminal stage of hyperparathyroidism-dependent bone pathology. Therefore, it is the extremely rare finding that brown tumor in the facial bone as the first manifestation of an hyperparathyroidism. We experience 1 case of brown tumor(50 years old female) that developed on Maxilla and mandible with no history of hyperparathyroidism. So we report this case with a literature review.
