title: [Hypertrophy of the masseter: a rare case associated with hypertrophic cardiomyopathy].
abstract: Masseteric hypertrophy is a rare, monolateral or bilateral lesion. The aetiology is often unknown and both congenital and acquired forms are reported in the literature. The authors report a case of masseteric hypertrophy associated with hypertrophic cardiomyopathy. Family history shows two brothers suffering from the same cardiac disease. Echography, computed tomography, EMG test and aspiration biopsy of masseteric muscle were performed. Echocardiography and HLA, B and C antigens of 16 relatives were also performed. In the report case the authors hypothesized a multifactorial background on a genetic basis.
