Bilateral Central Giant Cell Granulomas of the Mandible in An Eight Year-Old Girl with Noonan Syndrome (Noonan-Like/Multiple Giant Cell Lesions Syndrome)

Abstract

A number of conditions can present with lesions that histologically are indistinguishable from the central giant cell granuloma (CGCG) of bone, including brown tumors of hyperparathyroidism, cherubism, and, less commonly, a number of inherited syndromes. We report a case of an eight-year girl who presented with bilateral CGCGs of the posterior mandible. Characteristic facial features, reported increased post-operative bleeding and history of pulmonary stenosis led us to suspect a diagnosis of Noonan syndrome. A medical geneticist confirmed this on further evaluation. This case report will discuss the salient features of this diagnosis.
