BACKGROUND Parathyroid adenoma with cystic degeneration is a rare cause of primary hyperparathyroidism. The clinical and biochemical presentation may mimic parathyroid carcinoma. CASE PRESENTATION We report the case of a 55 year old lady, who had longstanding history of depression and acid peptic disease. Serum calcium eight months prior to presentation was slightly high, but she was never wo...

Primary hyperparathyroidism (PHPT) is caused by excessive autonomous secretion of parathormone (PTH), usually as a result of a parathyroid adenoma (80-85%), and less frequently due to parathyroid gland hyperplasia (15%-20%) or carcinoma (1%) (Kaplan et al.1991). Patients often suffer from mild subjective symptoms such as weakness and tiredness, but if untreated, symptoms progess to include deme...

Carcinoma of the parathyroid gland is rare, constituting about 1% of most series of patients with hyperparathyroidism. In 1969 a collective review identified forty-six unequivocal cases, and since then a further seven cases have been described in the literature. A brief review of the condition is presented, and one further case of hyperfunctioning adenocarcinoma of the parathyroid gland is repo...

Hyperparathyroidism (HPT) is an endocrine disorder characterized by high secretion of parathyroid hormone. Brown tumor one the skeletal manifestations HPT. Its overall prevalence low (about 0.1%). Involvement facial bones extremely rare. The mandible involved in 4.5% cases. Primary HPT (PHPT)with vitamin D deficiency worsens clinical course. Parathyroid adenoma detected ectopic places with a ra...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013203396 DESCRIPTION A man in his 30s with a history of end-stage renal disease (ESRD) and metastatic parathyroid carcinoma presented to the hospital with severe shortness of breath, hypercalcaemia and diffuse bone pain. Chest radiograph (figure 1A) demonstrated profound demi...

Parathyroid carcinoma constitutes less than 1% of primary hyperparathyroidism. The exact etiology is not known. Prior radiation to neck, chronic renal failure and genetic factors are thought to play a role. The male to female ratio is one. Parathyroid carcinomas are slow growing, have a tendency to recur locally and metastasize late. 95% of parathyroid carcinomas are functioning. The major dist...
