UNLABELLED Parathyroid carcinoma is a rare disease leading to severe hypercalcemia due to hyperparathyroidism. Surgery is the primary treatment option. A more progressive form of the disease is characterized by parathyrotoxicosis, and subsequent hypercalcemia is the most common cause of death. We report a case presenting with severe hypercalcemia due to parathyrotoxicosis from parathyroid carci...

IgG Heavy Chain Disease (γHCD) is a rare plasma cell disorder. Hypercalcemia related to plasma cell dyscrasias is related to non-PTHrP related mechanisms. Here we describe the first case of a patient with γHCD and PTHrP related hypercalcemia. Methods: Patient case derived from chart review from 2011 to 2015. Literature review performed searching PubMed 1968-current. Results: The patient was dia...

UNLABELLED A de novo heterozygous inactivating mutation of calcium-sensing receptor (CASR) gene typically causes neonatal hyperparathyroidism (NHPT) with moderate hypercalcemia and hyperparathyroid bone disease. We present a case of asymptomatic hypocalciuric hypercalcemia with a de novo heterozygous mutation in CASR, S591C, which is primarily reported to be responsible for NHPT. A 54-year-old ...

Vitamin D deficiency state is endemic to the Kashmir valley of the Indian subcontinent. Physicians often treat patients with high doses of vitamin D for various ailments and on occasion the prescribed doses far exceed the requirements of the patients. Ten cases of hypercalcemia due to vitamin D intoxication are presented with features of vomiting, polyuria, polydipsia, encephalopathy and renal ...

BACKGROUND Hypercalcemia is common in primary hyperparathyroidism malignancies and even in tuberculosis. Interestingly, systemic lupus erythematosus (SLE) rarely presents with hypercalcemia. CASE REPORT We describe an interesting case of SLE in a patient who was otherwise thought to have either tuberculosis or a malignancy. The patient initially presented with feeling unwell, with generalized...

Osteoprotegerin (OPG), a novel, secreted tumor necrosis factor receptor family member that inhibits osteoclast formation and activity was examined for its activity in a syngeneic tumor model of humoral hypercalcemia of malignancy. Normal mice bearing Colon-26 tumors develop increases in both parathyroid hormone-related protein (PTHrP) expression and plasma PTHrP, marked hypercalcemia, and incre...

BACKGROUND Hypercalcemia is a common problem in clinical practice and can be related to endocrine disorders or malignant disease, especially in elderly patients. Although rare, other causes can also be responsible. CASE REPORT Granulomatous inflammation of the skin and lymph nodes induced by intravenous or injectable silicone is a rare condition of hypercalcemia that is usually not within the...

Purpose. To describe successful palliation of a patient with metastatic adamantinoma presenting with lung metastases and hypercalcemia resulting from a parathormone-like substance released from the tumor.Methods and materials. The records of a patient with a history of a tibial adamantinoma who presented with symptoms of hypercalcemia 20 years after the original surgery, as well as the literatu...

55-year male of Asian descent presented with weight loss, lethargy, drowsiness and low grade fever without cough. Examination revealed crackles in the chest but no focal neurological deficit. Chest X ray revealed an infiltrate consistent with tuberculosis. Biopsy of infiltrate was negative for malignancy. Corrected calcium level revealed parathyroid independent hypercalcemia. Further diagnostic...

Disturbances of calcium metabolism such as hypercalcemia or/and hypercalciuria in the course of sarcoidosis can be a cause of renal failure in some patients. Life threatening hypercalcemia in sarcoidosis patients is not very frequent. Severe hypercalcemia leading to renal insufficiency is a very rare condition. We present a case of 53-year old man who was admitted to Department of Lung Disea...
