Abstract

This case series reports familial cases of nodular oncocytic hyperplasia (NOH) diagnosed in a mother and her son, 15 years apart. A 39-year-old man presented in 2003 with a lump below his left ear. Magnetic resonance imaging (MRI) performed showed multifocal parotid nodules and a diagnosis of NOH was histopathologically confirmed following left total parotidectomy. Two years later, he represented with similar symptoms on the right side. NOH was diagnosed following excision of his right parotid gland. In 2018, his 73-year-old mother presented with left ear pain and a lump below her left ear. An MRI scan showed multiple lesions within both parotid glands and bilateral NOH was once again diagnosed following a left superficial parotidectomy and right total parotidectomy. We believe that this is the first reported case of bilateral familial NOH.
