PARATHYROID CARCINOMA WITH LACK OF CLINICAL SYMPTOMS: A CASE REPORT AND REVIEW OF LITERATURE.

CONTEXT

Parathyroid carcinomas (PC) are rare. Imaging and laboratory tests can suggest a diagnosis of PC, but pathological examination is ultimately required to confirm the diagnosis.

OBJECTIVE

The clinicopathologic data, diagnosis, and treatment of a case of PC diagnosed in our hospital in 2022 are retrospectively summarized in this case report to improve the understanding, diagnosis, and differential diagnosis of this disease.

DESIGN

Case report.

SUBJECTS AND METHODS

Herein, we present the case of a 35-year-old man who presented with imaging and laboratory findings suggestive of a parathyroid neoplasm.

RESULTS

The patient underwent radical resection of the tumor, which was histopathologically diagnosed as PC.

CONCLUSION

In this case, the clinical manifestations of PC were insidious, and the histological features had to be differentiated from tumors, such as parathyroid adenoma, clear cell renal cell carcinoma, and medullary thyroid carcinoma; thus, its diagnosis was challenging.
