| Abstract |
Hypercalcemia is found frequently in patients with cancer. Besides the etiology related to the malignancy, other causes should be considered in the differential diagnostic, as primary hyperparathyroidism, granulomatous diseases and the use of thiazide diuretics. We present a case report of a severe hypercalcemia due to a rare association and review the relevant literature. A female patient, 57 years old, sent to the Endocrinology Service of Hospital das Clínicas da Universidade do Paraná (SEMPR) in order to investigate severe hypercalcemia with frequent need of hospitalization. The patient was in chemotherapy treatment for recurrence of clear cell renal cancer. During the investigation she presented high level of parathyroid hormone (PTH) and parathyroid scintigraphy suggestive of hyperplasia/ adenoma of parathyroid, histopathological diagnosis was confirmed after parathyroidectomy. After surgery the patient presented undetectable levels of PTH. However, she continued with progressive increase of serum calcium, with no signs of bone metastases or change in vitamin D metabolism. The investigation showed high levels of PTH-related protein (PTHrP), leading us to the diagnosis of hypercalcemia of malignancy. The patient presented severe hypercalcemia due to the rare association of primary hyperparathyroidism and humoral hypercalcemia of malignancy due to secretion of PTHrP by tumor cells. The presence of isolated primary hyperparathyroidism, as a cause of hypercalcemia in cancer patients, has been described in approximately 5-10% of the patients. However, the association of primary hyperparathyroidism and humoral hypercalcemia of malignancy (which means with concomitant elevation of PTH and PTHrP) is rare, only three cases have been described in the literature.

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 October 2015.
All research outputs
#15,739,010
of 25,371,288 outputs
Outputs from Archives of Endocrinology and Metabolism
#291
of 800 outputs
Outputs of similar age
#195,731
of 361,157 outputs
Outputs of similar age from Archives of Endocrinology and Metabolism
#2
of 8 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 800 research outputs from this source. They receive a mean Attention Score of 3.3. This one has gotten more attention than average, scoring higher than 62% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 361,157 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 8 others from the same source and published within six weeks on either side of this one. This one has scored higher than 6 of them.
