Background Parathyroid hormone (PTH) and Dickkopf-related protein 1 (DKK-1) have been mentioned together at the intersection of autoimmune rheumatologic diseases (ARDs) and osteoimmunology. However, few studies have evaluated the association between primary hyperparathyroidism (PHPT) and ARDs. Methodology This retrospective study included 225 PHPT patients and 386 patients with thyroid nodules as a control group. The electronic hospital records of all patients were screened going back nine years for the presence of ARDs. Patients who were diagnosed at least three months ago, had complete serologic tests, and were continuing with rheumatologic follow-up were included. Results The prevalence of ARDs in the PHPT group was 9.77% (22/225), while the prevalence of ARDs in the CG was 1.04% (4/386, p < 0.001). The prevalence of rheumatoid arthritis in the PHPT group was 4.4% (10/225), ankylosing spondylitis 3.1% (7/225), systemic lupus erythematosus 0.88% (2/225), Behçet's disease 0.88% (2/225), and mixed connective tissue disease 0.44% (1/225). Of the 22 patients with ARDs, 21 (95.45%) were diagnosed before they were diagnosed with PHPT, and the median time from diagnosis with ARD to the onset of PHPT was 36 months (interquartile range = 61.5). Logistic regression analysis showed a positive correlation between the duration of PHPT and ARDs (odds ratio (OR) = 1.06; 95% confidence interval (CI) = 1.02-1.09, p < 0.001) and a negative correlation between ARDs and calcium levels (OR = 0.26; 95% CI = 0.09-0.79, p = 0.018). Conclusions The prevalence of ARDs increased in PHPT patients and PHPT accompanying ARDs developed after rheumatologic disease. ARDs with PHPT are cases with a prolonged duration of PHPT and mildly elevated calcium, probably preceded by parathyroid hyperplasia. Therefore, the factors that cause ARDs may trigger a process that leads to mild PHPT.

Hyperparathyroidism usually presents asymptomatically with elevated levels of calcium and parathyroid hormone; this biochemical imbalance establishes the diagnosis. In 80-85% of cases of primary hyperparathyroidism, singular parathyroid adenomas occur. In rare cases, this problem occurs due to multiple adenomas, multiglandular hyperplasia, or parathyroid carcinoma. Recurrent primary hyperparathyroidism (R-PHPT), as demonstrated in this case, is defined as hypercalcemia that arises after six months of normocalcemia following initial surgery for PHPT. The aim of this report is to describe the diagnosis and management of three parathyroid adenomas in a patient, two of which occurred after an initial partial parathyroidectomy.

BACKGROUND
Parathyroid carcinoma and parathyromatosis are very rare diseases in patients on hemodialysis. Its pathogenesis, clinical features, preoperative diagnosis, and surgery are challenging. We describe a rare case of recurrent hyperparathyroidism due to synchronous parathyroid carcinoma and parathyromatosis.
CASE PRESENTATION
A 46-year-old Chinese woman was diagnosed with end-stage renal disease and received regular hemodialysis. Four years later, she experienced discomfort due to itching and was diagnosed with drug-resistant secondary hyperparathyroidism. Parathyroidectomy was performed, and her parathyroid hormone (PTH) levels were reduced. The pathology also revealed that the four nodules were parathyroid nodular hyperplasia without evidence of malignancy. Five years after surgery, the right subcutaneous nodule and left inferior nodule were detected by multiple imaging modalities, and the nodules were accompanied by recurrence itching and elevation of PHT. A complete resection of two nodules was performed, and the patient was diagnosed with parathyroid carcinoma and parathyromatosis. At 8 months postsurgery, her PHT and serum calcium levels were stable, and there were no signs of recurrence.
CONCLUSIONS
This is a rare case of synchronous parathyroid carcinoma and parathyromatosis in a patient with secondary hyperparathyroidism after parathyroidectomy. We suggest meticulous handling of parathyroid hyperplasia to avoid rupture and spillage during surgery, and precise pro-operation location by multiple imaging modalities is crucial for successful parathyroidectomy.

We aimed to explore the value of ultrasonic elastic imaging in the diagnosis of parathyroid hyperplasia and adenoma in patients with secondary hyperparathyroidism and provide more evidence for clinical treatment. Forty patients who were on dialysis and underwent parathyroid surgery were selected All patients underwent routine ultrasound, ultrasound elasticity examination and blood biochemical examination before surgery, including calcium, phosphorus, parathyroid hormone (PTH), etc. According to postoperative results, adenoma group and hyperplasia group were divided into 2 groups. Receiver operating characteristic curve was drawn to evaluate the diagnostic efficacy and combined diagnostic efficacy of each index. The PTH levels significantly differed between the adenoma and hyperplasia groups (P < .001). The volume and blood flow grades significantly differed between the adenoma and hyperplasia groups (P < .001) The minimum of the adenoma group was 14.62 ± 6.79 kPa, mean was 19.42 ± 6.29 kPa, and maximum was 24.25 ± 6.35 kPa which were significantly different from those in the hyperplasia group (P < .05). The combinations of more than 6 indicators in the diagnosis of parathyroid adenoma resulted in an area under the curve of 0.892 (P < .001), and the sensitivity and specificity were 78.9% and 97.4%, respectively. Shear wave elastography can be used as an effective tool to distinguish secondary parathyroid hyperplasia from adenoma. When combined with PTH, conventional ultrasound blood flow grading and volume measurement, it has higher diagnostic efficacy.

BACKGROUND
The most comon patohistological finding in primary hyperparathyroidism is adenoma of the parathyroid gland, followed by hyperplasia and the rarest is carcinoma. However, hyperplasia of the parathyroid glands (PTG) is most commonly found in secondary and tertiary hyperparathyroidism.
OBJECTIVE
To determine the relationship between the localization of the parathyroid glands and pathological diagnosis, as well as the prevalence of individual pathological diagnosis after surgery in patients with hyperparathyroidism.
METHODS
Analysis of retrospective-prospective database of 79 patiens who underwent parathyreoidectomy for hyperparathyroidism in the 7-year study period. Diagnostic methods were used to identify enlarged parathyroid glands as well as to determine their localization: ultrasound examination, scintigraphy and operative finding. Standard hematoxylin eosin staining was used for pathohistological diagnosis. A correlation analysis between parathyroid gland localization and pathohistological diagnosis was performed.
RESULTS
The median age of the patients were 51 age (range 20-73) and 67,1% of the patients were female. In the total number of surgically removed parathyroid glands (182), the most common pathohistological diagnosis was hyperplasia. Parathyroid adenoma was found in 21 cases. Other diagnoses (thyroid nodule / tissue, lymph node, thymus, cancer) were found in 11 cases, while a normal finding was found in 12 glands. Pathohistological diagnosis of hyperplasia and adenoma were more common in the lower parathyroid glands. Using the chi-square test, no association was found between pathohistological diagnosis and localization of enlarged parathyroid glands.
CONCLUSION
The most common pathohistological diagnosis in hyperparathyroidism was hyperplasia and was most commonly found in the inferior parathyroid glands. Adenoma as pathohistological diagnosis is also most commonly found in the lower parathyroid glands, but without statistical significance.

BACKGROUND
There is some evidence supporting the idea that double parathyroid adenomas represent a different entity from multiglandular hyperplasia; however, the distinction among them is not straightforward.
CASE PRESENTATION
We described a case of primary hyperparathyroidism (PHPT) with pronounced clinical manifestations, caused by a bilateral giant parathyroid adenoma. A 34-year-old Hispanic/Latino male was diagnosed with PHPT caused by two giant parathyroid adenomas. The preoperative tests were neck ultrasound and computed tomography scan (CT-scan), showing two masses in the territory of parathyroid glands, bilaterally distributed (right was 31 × 18 × 19 mm and the left was 38 × 15 × 14 mm); sestamibi scan was not available. Parathyroid hormone (PTH) was highly elevated. Multiple complications of PHPT were present, such as bone lytic lesions, renal and pancreatic calcifications, and cardiovascular disease, the latter of which is an overlooked complication of PHPT. Multiple endocrine neoplasia 1 and 2 (MEN 1/2) were ruled out by the absence of clinical, biochemical, and radiological findings in other endocrine glands. The patient underwent subtotal parathyroidectomy with an intraoperative histopathological study; both intraoperative and definitive histopathology results were consistent with parathyroid adenomas; afterward, adequate suppression of PTH was assured, and later on, the patient presented hungry bone syndrome (HBS).
CONCLUSIONS
The diagnosis of double parathyroid adenomas is difficult. Regarding the similarities between multiglandular hyperplasia and parathyroid adenomas, this case report contributes to the further distinction between these two clinical entities. This case report also represents, in particular, the challenge of difficult diagnosis in places with limited resources, such as developing countries.
