A 57-year-old female was admitted to our hospital with general lassitude, loss of appetite, nausea, upper abdominal pain, thirst, polydipsia and polyuria. On admission, she had an asymmetrical pear-shaped tumor in the right supraclavicular region and severe hypercalcemia. Plasma C-PTH was elevated to 22.72ng/ml. Plasma calcitonin was also elevated to 336 pg/ml. She died of respiratory and cardiac failure of two weeks after admission without any positive response to the treatment, including hemodialysis. Pathohistologically, the tumor was a parathyroid adenoma. The concentrations of C-PTH, intact PTH and calcitonin in the tumor tissue were markedly high: 4.56 micrograms/g wet, 13.9 ng/g wet and 50.7 ng/g wet, respectively. Immunohistologically, the tumor cells and the fibrous stroma were stained strongly positive to rabbit anti-human calcitonin antibody and rabbit anti-human N-PTH antibody by indirect immunoperoxidase staining. Calcitonin-producing tumors, except for medullary thyroid carcinoma are rarely reported. To our knowledge, this is the first report of such a calcitonin-producing parathyroid adenoma associated with primary hyperparathyroidism.

A 57-year-old male, who had been suffered from hypertension and diabetes mellitus for 10 years, was admitted to the hospital because of thirst, lassitude and muscle wasting. On admission, his urinary excretion of 17-OHCS and plasma cortisol levels were elevated without diurnal variations. Plasma ACTH levels were found to be very low with repeated determinations. Dexamethasone suppression test, 2 mg 4 times a day orally for 2 days, showed no changes in plasma cortisol levels and only a mild reduction in urinary 17-OHCS excretion. Estimation of urinary catecholamines showed an increase only in norepinephrine. Abdominal computerized tomography and radionuclide scanning of adrenal glands with 131I-adosterol demonstrated a well-defined adrenal mass in the left side without apparent changes in the right side. 131I-metaiodobenzylguanidine scintigraphy was negative. At surgery, his left adrenal medulla was found to be hypertrophic in addition to the cortical tumor. The left adrenal gland was also removed. After surgery, excretion of urinary catecholamines fell to nearly the normal range and he was discharged without insulin and antihypertensive drugs. Microscopically, the cortical tumor is an adenoma consisting of lipid laden cells and eosinophilic compact cells. Medullary cells were distinctly hyperplastic in appearance and many of the cells were extensively vacuolated, suggesting an active functional status. The present report describes a patient with Cushing's syndrome who showed increased urinary catecholamine excretion due to the possible coexistence of adrenal medullary hyperplasia. As far as we know, this is the first case of Cushing's syndrome with this abnormality.

A 62 year-old female patient with polycystic disease and chronic renal insufficiency who had required dialysis for 3 years, presented with diffuse but predominantly lumbar bone pain associated with lassitude. Radiologic studies showed diffuse osteoporosis and destruction of the 4th lumbar vertebra. Calcium levels were normal (2.30-2.50 mmoles) with increased PTH levels (1820 microliter Eq/ml). The presence of a cervical mass suggested a diagnosis of hyperparathyroidism. A cervical exploration was performed with ablation of 4 parathyroid glands and autotransplantation of a portion of the left inferior gland into the arm. Pathological studies showed the existence of carcinoma in the right superior and inferior glands, adenoma of the left superior gland and hyperplasia of the left inferior gland. The association of hyperplasia, adenoma and carcinoma could be explained by an initial hyperplasia of the 4 glands due to renal insufficiency, with subsequent transformation of 3 into adenomas of which 2 became cancerous. The patient's status was significantly improved following surgery.

A middle-aged woman presented with a history of constipation, easy fatigue, depressive mood, lassitude, polydipsia, and polyuria. The patient posed a challenging diagnostic dilemma due to the presence of persistent severe hypercalcemia and relative lack of clinically manifested symptoms. Clinical, biochemical, and genetic examinations confirmed the diagnosis of familial hypocalciuric hypercalcemia as a result of C562Y calcium-sensing receptor mutation, and a coexisting parathyroid adenoma. After adenectomy, the patient's clinical situation improved markedly, and a modest equilibrium hypercalcemia persisted. This case presents an unusual combination of two relatively common endocrine disorders.

A case was a 67-year-old man, who presented an inferior limb lassitude approximately in January 2009. We noted a thyroid gland mass by examination and referred for a further checkup. Biochemical examination of blood showed hypercalcemia, a high iPTH level of 2,190. The cervical echography evidence showed a mass image of the border regular in the back of inferior pole of left thyroid gland. It also revealed a mass image with the calcification in the inferior pole of left lobe of thyroid gland at the same time. We performed aspiration biopsy cytology for a thyroid gland mass, and it was class IIIa. We also performed parathyroidectomy and left lobe of thyroid gland ablative surgery because of a diagnosis of the hyperparathyroidism confirmed a primary parathyroid adenoma. Preoperative pathological diagnosis was adenoma. However, histopathology laboratory findings showed it to be of adenocarcinoma of the parathyroid, which metastasized into the thyroid. Many times parathyroid cancer preoperative diagnosis is inconclusive. So we are reporting our experience with parathyroid cancer metastases to the thyroid for reference.
