The management of metastasis from parathyroid carcinoma (PC) is an unusual challenge. Systemic therapy has minimal effect on the course of the disease and its associated hypercalcemia. Resection of isolated pulmonary metastases is an attractive option in the setting of recurrent hypercalcemia. We report a case of a patient who underwent resection of multiple functional PC pulmonary metastases almost 20 years after the original neck resection. The patient originally presented in 1982 with what was thought to be hyperparathyroidism secondary to a parathyroid adenoma. Surgical exploration revealed the presence of a well differentiated PC. The patient was transiently normocalcemic, but underwent surgical exploration in 1993 and 1996 for recurrent PC in the neck. The patient again improved, but presented in 2001 with diffuse arthralgia, fatigue, malaise, weight loss, and decreased appetite. She was found to have a serum calcium of 12.7 mg/dL and an intact parathyroid hormone of 1542 pmol/L. Computed tomography identified the presence of two right-sided and two left-sided pulmonary masses. Sternotomy with bilateral pulmonary metastectomy was performed. Functional PC metastasis was confirmed on pathological examination. One year following metastectomy the patient is hypocalcemic, requiring oral calcium and vitamin D supplementation. Functional pulmonary metastasis from PC is a rare cause of hypercalcemia. Complete resection of isolated pulmonary metastases can provide effective palliation with long-term survival.

We report on a young female who had presented with fatigue, bilateral knee pain and gait disturbance. Primary hyperparathyroidism was diagnosed together with splenomegaly and anemia. Bone marrow biopsy revealed myelofibrosis. A parathyroid adenoma was excised during surgical intervention. As early as three months after the operation, hematologic parameters improved along with bone markers without any other intervention. The control bone marrow biopsy demonstrated well marked regression in marrow fibrosis. Her spleen has also gradually decreased in size. These findings indicate that her myelofibrosis was the result of primary hyperparathyroidism. Anemia associated with primary hyperparathyroidism may be due to bone marrow fibrosis.

A 62-year-old patient with low grade fever, fatigue, arthralgia and newly discovered mitral regurgitation was diagnosed with subacute endocarditis. Streptococcus bovis grew from all six blood culture bottles. Streptococcus bovis is known to be associated with gastrointestinal neoplasias. Therefore a colonoscopy was performed and two polyps were removed. Histological analysis revealed a tubulovillous adenoma and a serrated adenoma. Colonoscopy is mandatory for all patients with Streptococcus bovis endocarditis even without any symptoms for colorectal neoplasia. The significance of Streptococcus bovis for the carcinogenesis of colorectal neoplasias and the possible alternative pathway for colorectal carcinomas through serrated adenomas will be discussed.

Brown tumor is a focal lesion of the bone caused by primary or, less commonly, secondary or tertiary hyperparathyroidism (HPT). While the mandible is the most frequently involved bone in the head and neck region, atypical involvement of the cranium in the area of the sphenoid sinus is exceedingly rare. In the literature, a unique case of brown tumor of the sphenoid sinus was reported in a patient with primary HPT. We present a case of sphenoid sinus and occipital bone brown tumor associated with primary HPT. A 47-yr-old woman presented a 2-yr history of headaches, dizziness, diffuse body and articular pain, fatigue, and a 6-month history of intermittent nausea and vomiting, polydipsia, and polyuria. Magnetic resonance imaging (MRI) demonstrated an expansive mass lesion in the sphenoid sinus with erosion of the sellar floor and medial wall of the right orbit, and expansion in the medulla of bone. Examination of biopsy specimens obtained from sphenoid sinus mass confirmed the diagnosis of brown tumor. The biochemical laboratory studies showed elevation of parathyroid hormone and confirmed the diagnosis of primary HPT. Excision of a parathyroid adenoma affected the metabolic status into normalizing. At the follow-up of 12 months postoperatively, the size of sphenoid sinus brown tumor decreased and the mass of occipital bone disappeared. In conclusion, this is a first report of primary HPT masquerading as a destructive fibrous sphenoid sinus brown tumor associated with a mass lesion of occipital bone and hypercalcemia in the literature.

We report a case of adrenal black adenoma associated with Cushing's syndrome. A 41-yr-old man presented to our hospital with a 6-yr history of severe hypertension and general fatigue, and a 1-mo history of diabetes mellitus. Physical examination disclosed cushing-oid manifestations. His serum cortisol concentrations ranged from 14.0 to 15.4 microg/dL, with an ACTH level <5 pg/mL. Urinary free cortisol level was increased (125 microg/d). Cortisol was not suppressed on the overnight 1 mg oral dexamethasone suppression test (DST), 2-d low-dose DST, and 2-d high-dose DST. Abdominal computed tomography and magnetic resonance imaging studies revealed a solid round tumor approx 3 cm in diameter, located in the left adrenal gland. Left adrenalectomy was performed; the surgical specimen revealed a black ade-noma consisting of compact cells within numerous pigments that seemed to be lipofuscin in nature.

The intraductal tubular adenoma (ITA), pyloric gland type, of the pancreas is an uncommon benign tumor, akin to the pyloric gland type adenoma of the gallbladder. We report 6 cases of ITA of the pancreas: 3 male and 3 female aged 50 to 79 years (mean, 63.5 years; median, 65 years); all were examined clinicopathologically. Four patients showed no symptoms, but appetite loss and/or general fatigue presented in two. Grossly, all tumors formed a localized polypoid mass protruding into the lumen of the dilated pancreatic duct. Five of the six tumors were found within the main duct, and the other arose within the branch duct of the pancreas. Microscopically, the tumors were composed of closely packed tubular glands resembling pyloric type glands. They were lined by columnar or cuboidal epithelial cells with foci of mild to moderate dysplastic change. In 2 cases, the adjacent pancreas showed foci of intraductal papillary-mucinous adenoma. Histochemically, the tumors largely showed neutral mucin with a lesser amount of acidic mucin made up mainly of sialomucin. Endocrine cells were found in five tumors. Immunohistochemically, all tumors were labeled with M-GGMC-1 and MUC6, whereas MUC1 and MUC2 stains were negative. Pepsinogen II was positive in 5 tumors; thus, the results displayed a pattern of differentiation similar to those of ordinary gastric pyloric or metaplastic pyloric glands. DPC4 expression was maintained in all tumors and p53-positive nuclei were hardly encountered. All patients are alive with no evidence of disease 3 to 10.5 years after surgical resection.

Primary hyperparathyroidism (PHPT) is characterized by excessive PTH secretion in respect to calcium homeostasis needs, due to parathyroid adenoma (80% of cases), hyperplasia (15-20%), or carcinoma (1-2%). In familial forms of PHPT, several mutations have an established role: menin gene for MEN type 1, RET for MEN type 2a, calcium-sensing receptor gene for familial hypocalciuric hypercalcemia, parafibromin gene for PHPT-jaw tumour and carcinoma. Etiology of sporadic adenomas (80% of PHPT cases) is less defined, being most commonly found a mutation of menin gene or activation of PRAD1 oncogene. In recent years, the classical features of the disease became less common. Typically, bone involvement is now represented by a reduced bone mass at skeletal sites more rich in cortical tissue. Prominently trabecular skeletal sites are relatively spared, because of the anabolic effects of a slight PTH excess on trabecular tissue. PHPT patients may have increased fracture risk, though it is not clear why bone damage is more severe in a subgroup of patients. Clinical features of hypercalcemia may be fatigue, anorexia, thirst, and polyuria. Vague neurological and psychiatric symptoms, such as weakness, anxiety, depression, paresthesias, and muscular cramps may ameliorate after parathyroidectomy. Recent reports indicate increased cardiovascular mortality in PHPT patients. Diagnosis is based on the detection of hypercalcemia, together with inappropriately high serum PTH levels. Preoperative localization of the diseased glands is mandatory in persistent or recurrent PHPT, as like as when minimally invasive surgery is planned. High resolution ultrasonography and SPECT double-phase 99m Tc-sestamibi scintigraphy are the most commonly employed techniques. Intraoperatory PTH assay may confirm successful surgery when serum concentrations decrease more than 50%. Surgical therapy is indicated in patients with renal or skeletal complications, such as in those with previous parathyrotoxic crisis. Many surgeons in recent years adopted minimally invasive parathyroidectomy. Medical treatment is an option for patients unwilling or unfitted for surgery because of severe concomitant diseases. Employed therapy includes estrogens, SERMs, bisphosphonates and calcimimetics.

Parathyroid carcinoma constitutes less than 1 % of primary hyperparathyroidism. The male to female ratio is approximately equal and the mean age at presentation is 40 years. In about half of the patients there is a palpable cervical mass, and serum calcium level is usually above 14 mg/dl. In a case report we present a 21-year-old man with a non-tender, non-mobile bulging mandibular mass. He suffered from fatigue, recent weight loss, hoarseness, polydipsia, polyuria, hematuria, recurrent renal stones and bouts of constipation and diarrhea. A mandibular biopsy confirmed brown tumor. Serum calcium level was 15.4 mg/dl. Cervical ultrasound revealed a hypoecho area suspicious of parathyroid adenoma. Parathyroid carcinoma was later confirmed and en bloc resection was performed. During a two-year follow up there has been no evidence of recurrence or hypercalcemia. This unique case of parathyroid carcinoma in conjunction with brown tumor is the second reported case worldwide.

We present case report of primary hyperparathyroidism treated surgically as well as a review of literature concerning this subject. The disease of not well known etiology presents with elevated parathormon levels and hypercalcemia. Primary hyperparathyroidism which states 85% percent of all kinds of hyperparathyroidism is usually parathyroid adenoma, in 11-15% glandular hyperplasia and in 1-4% parathyroid cancer. Clinical symptoms are muscle weakness and fatigue, nephrolithiasis, occasionally peptic ulcers, pancreatitis, hypertension. Laboratory test reveal increased level of PTH, hypercalcemia, elevated alkaline phosphatase levels and decreased phosphorus levels. Diagnostic imaging techniques such as ultrasonography, MRI or CT have sensitivity about 52-75%. Highest sensitivity in localization of ectopic parathyroid adenoma has sestamibi scintigraphy with technetium-99. Skeleton x-rays show typical changes in distal parts of bones and osteopenia. Treatment of choice is surgical excision of adenoma. Normalization of PTH and calcium levels after surgery and improvement of renal, musculoskeletal and circulatory system function could be achieved in 95%. Most common complications are recurrent laryngeal nerve injury, hypo- or hyperparathyroidism, bleeding or stridor.

We report a case of bone pain associated with primary hyperparathyroidism in a patient with sickle cell disease. A 17-year-old girl with sickle cell disease (SS phenotype) was seen for bilateral knee and back pain. She had had recurrent severe vaso-occlusive crises and acute chest syndrome in the course of her disease. In the last 2 years, she had frequent visits to the emergency department for severe bone pain. She complained of long-standing fatigue and lethargy. Her physical examination was normal. Hydroxyurea treatment, as well as and long- and short-acting narcotics were given, with little improvement in symptoms. Poor compliance with medication, family dysfunction, and potential narcotic addiction were felt to be significant contributors to the patient's symptoms. She was incidentally found to have an extremely elevated total calcium level of 3.19 mmol/L (range: 2.25-2.76) with an ionized calcium level of 1.9 mmol/L (range: 1.15-1.35). Phosphorus level was 0.82 mmol/L (range: 0.90-1.50), alkaline phosphatase level was elevated at 519 U/L (range: 10-170), and parathyroid hormone level was extremely high at 1645 pg/mL (range: 10-60). Her renal function was normal. Ultrasonography of the neck and a Sestamibi scan revealed a single left inferior parathyroid adenoma adjacent to the thyroid lobe. There was no evidence of an underlying multiple endocrine neoplasia. The patient was diagnosed with primary hyperparathyroidism. Fluid hydration, hydrocortisone, calcitonin, and bisphosphonates were initiated for acute hypercalcemia management before surgical excision of the left parathyroid adenoma. On review of previous blood work, a borderline calcium level of 2.72 was present 18 months before this admission. Two years postsurgery, she has normal renal function, calcium, and parathyroid hormone levels. The weekly visits to the emergency department for pain episodes decreased to 1 every 2 months within the first few months after her surgery. The decrease in pain episodes, even if it coincided with the treatment of primary hyperparathyroidism, may still reflect the natural evolution of sickle cell disease in this patient. However, the high morbidity associated with primary hyperparathyroidism was successfully prevented in this patient. Primary hyperparathyroidism is rare in childhood. In a recent study, it occurred more commonly in female adolescents and was because of a single adenoma, as in our patient. Significant morbidity, mainly secondary to renal dysfunction, was because of the delay in diagnosis after the onset of symptoms (2.0-4.2 years), emphasizing the need for a rapid diagnosis. Sickle cell disease affects approximately 1 of every 600 blacks in North America. Acute episodes of severe vaso-occlusive crisis account for > 90% of sickle cell-related hospitalizations and are a significant cause of morbidity in patients. There is no known association between sickle cell disease and primary hyperparathyroidism, and this case is most probably a random occurrence. However, as emphasized by this case report, pain may also be a harbinger of other disease processes in sickle cell disease. Because management may vary, we suggest that care providers consider the diagnosis of vaso-occlusive crisis as the diagnosis of exclusion and that other etiologies for pain be envisaged in this patient population, especially in the presence of prolonged pain or unusual clinical, radiologic, or biological findings.
