Peripheral Giant Cell Granuloma of the Jaws as First Sign of Primary Hyperparathyroidism: A Case Series

Rare Case of a Peripheral Giant Cell Granuloma of the Jaw as First Manifestation of Primary Hyperparathyroidism

Giant cell granulomas (GCG) are uncommon benign tumor-like lesions mostly arising in the oro-facial area. They are more common in women and occur in patients younger than 30 years. Lesions restricted to the bone are referred to as central giant cell granulomas (CGCG), and those developing primarily on soft tissues are termed peripheral giant cell granulomas (PGCG). Both types are histologically identical. The combination of both clinical examination and radiography allows for the differentiation of those two variants. On rare occasions GCG, and especially CGCG, may develop in relation to hypercalcemia linked to hyperparathyroidism (HPT). In those cases, the GCG treatment prognosis is closely linked to the HPT management. Therefore, patients diagnosed with a GCG must be investigated to search for an HPT. Reported herein is a rare clinical case of a mandibular PGCG which led to the diagnosis of primary HPT.

Oral and Maxillo-Facial Manifestations of Systemic Diseases: An Overview

Many systemic (infective, genetic, autoimmune, neoplastic) diseases may involve the oral cavity and, more generally, the soft and hard tissues of the head and neck as primary or secondary localization. Primary onset in the oral cavity of both pediatric and adult diseases usually represents a true challenge for clinicians; their precocious detection is often difficult and requires a wide knowledge but surely results in the early diagnosis and therapy onset with an overall better prognosis and clinical outcomes. In the current paper, as for the topic of the current Special Issue, the authors present an overview on the most frequent clinical manifestations at the oral and maxillo-facial district of systemic disease.
