Abstract 6265: FLCN variants and their role in parathyroid cancer and atypical parathyroid tumors
Cancer ResearchAbstract Parathyroid carcinoma (PC) is rare, poses challenges in definitive diagnosis and treatment, and carries a high rate of recurrence and mortality. Atypical parathyroid tumors (APT) have histopathologic features of malignancy but lack unequivocal evidence of invasion and are of uncertain malignant potential.

Preoperative CALLY Index for Identifying Atypical Parathyroid Tumors
Clinical EndocrinologyABSTRACT Background Atypical parathyroid tumors (APTs) are diagnostically challenging neoplasms that display worrisome histopathological features but do not meet the criteria for carcinoma. Conventional biochemical and imaging parameters have limited discriminatory accuracy, and no validated ...

Brown tumors are one of the characteristics of primary hyperparathyroidism, although, in some cases, they are noted with secondary hyperparathyroidism as well. The authors present a case of a 50-year-old woman with primary hyperparathyroidism caused by parathyroid carcinoma with an unusual location of a brown tumor in the calcaneus. She first presented

Differential diagnosis of atypical parathyroid tumors (APT) and parathyroid carcinomas (PC) is important in determining further management and prognosis. Morphologic diagnosis is sometimes difficult, in which case it is supplemented by immunohistochemical (IHC) examination. Objective.

We present a parathyroid carcinoma with hyalinizing trabecular architecture and a prominent spindle-cell component. The tumor closely mimicked a hyalinizing trabecular tumor of the thyroid due to its trabecular growth, eosinophilic hyalinized stroma, and nuclear features including grooves and intranuclear pseudoinclusions.

A Rare Atypical Parathyroid Tumor In Young Adult Man : A Diagnostic Challenge
International Journal of Drug Delivery TechnologyParathyroid carcinoma (PC), an extremely rare endocrine malignancy, was found to coexist synchronously with papillary thyroid carcinoma (PTC) in a 23-year-old male, presenting a unique and complex case. The patient displayed signs of severe primary hyperparathyroidism, including weakness, bone pain, and weight loss, supported by severe hypercalcemia ...
