Current Knowledge on Atypical Parathyroid Tumors and Emerging Strategies for Risk Stratification [PDF]

Endocrinology and Metabolism
Atypical parathyroid tumors (APTs) are an uncommon subset of parathyroid neoplasms that carry substantial clinical relevance because of their histological and clinical resemblance to parathyroid cancer.

Parathyroid carcinoma and atypical parathyroid tumor: analysis of an Italian database

European Journal of Endocrinology
Abstract Objective Atypical parathyroid tumor (aPT) and parathyroid carcinoma (PC) are extremely rare parathyroid neoplasms, accounting together for <2% of all parathyroid tumors. They often present an overlapping clinical phenotype, sharing clinical, biochemical, and some histological features.

The Role of Parafibromin, Galectin-3, HBME-1, and Ki-67 in the Differential Diagnosis of Parathyroid Tumors

Oman Medical Journal, 2015
Objectives: Parathyroid carcinoma (PC) is a rare parathyroid tumor compared to parathyroid adenoma (PA) and atypical parathyroid adenoma (APA). Recent studies have suggested parafibromin has a role in the differential diagnosis of parathyroid tumors.

Atypical parathyroid tumor: clinical and parathyroid hormone response to surgical treatment. [PDF]

Ann Surg Treat Res, 2023
Primary hyperparathyroidism (PHPT) is caused by typical adenoma (TA), multiglandular disease (MD), or parathyroid carcinoma (PC), and in a smaller percentage of cases by atypical parathyroid tumor (APT). The objective of this study is the retrospective analysis of clinical features and parathyroid hormone (PTH)/calcium response to surgery in patients ...

Atypical Parathyroid Tumor and Hyperparathyroidism, and Their Association With the CDC73 Mutation in a Pediatric Patient. [PDF]

Cureus
Primary hyperparathyroidism (PHPT) is rare in the pediatric population and often presents with pronounced symptoms due to delayed recognition. Atypical parathyroid tumors, or neoplasms of uncertain malignant potential, are even less common in children and may indicate an underlying genetic disorder.
