Primary squamous cell carcinoma of parotid gland with sialo-cutaneous fistula: a rare clinical case

Primary squamous cell carcinoma (PSCC) of parotid gland, as well as for other salivary glands, is a rare and aggressive malignancy that accounting for less than 1% of salivary glands neoplasms. PSCC is an aggressive neoformation of the elderly with a mean age of 64 years and a male-female ratio about 2:1. It is a rapidly advancing lesion which, if not recognised and treated early, results in high morbidity and mortality. Despite radical surgery and adjuvant radiotherapy, prognosis of this cancer continues to be poor. Patients typically present in an advanced stage with rapidly enlarging mass around the angle of mandible, often accompanied by cervical lymph-adenopathy and facial nerve involvement. In our paper, we present a case about a 98 years old woman, with an history of 3 months painful growing mass at the left angle of mandible with a sialo-cutaneus fistula and left lip paralysis. We successfully perform an intervention to remove the mass, scarifying the mandibular and the cervical branches of left facial nerve which were involved by the neoformation grown. After one week the patient had a perfect recovery and the restraint of the mouth was good enough to consent to her to eat.
