Early detection of cherubism with eventual bilateral progression: a literature review and case report

Bone-related disorders of the jaw: A clinico-radiological diagnostic algorithm

Bone-related disorders of the jaw (BRDJ) include a spectrum of non-neoplastic and neoplastic lesions of the maxillofacial region that have been recently classified into fibro-osseous lesions, giant cell lesions and osseous tumours. The histopathological features of BRDJ can be similar and overlie each other. Imaging is important in order to reach a specific diagnosis. However, the appearance of BRDJ on imaging is non-specific in some cases. Computed tomography (CT) and magnetic resonance imaging (MRI) are used for accurate localisation, characterisation of the tumour matrix, delineation of the lesion extension and establishment of the relation of BRDJ to the surrounding structures. Imaging is usually done to detect the relationship with the adjacent surrounding vital structures and to diagnose aggressive forms, malignant transformation and associated syndromes. The correlation of the demographic findings, the location and the clinical presentations with the imaging features are important for the diagnosis of BRDJ. The proposed clinico-radiological diagnostic algorithm with CT and MRI helps a specific diagnosis to be reached in some cases.

True Unilateral Mandibular Cherubism: A Literature Review and Case Report

Cherubism is a self-limiting fibro-osseous disorder that is classically characterized by bilateral mandibular swelling in the first or second decade of life. Three cases of unilateral cherubism have been described in the literature; however, bilateral involvement did not eventually develop in only 1 case. Histopathologic variation and genetic heterogeneity complicate the diagnosis and treatment of a unilateral benign giant cell lesion of the jaws. Our case report presents a 13-year-old male patient with unilateral posterior mandibular swelling that proved to be histologically and clinically consistent with unilateral cherubism. Involution of the unilateral lesion with no bilateral involvement occurred during 8 years of serial examination.
