Solitary Fibrous Tumor of the Oral Cavity: Case Report and Pathologic Consideration

Abstract

A 94-year-old Caucasian man affected by senile dementia came under our observation due to a bulky mass of the oral cavity advancing from the labial rim. Due to his mental condition, the patient had always refused surgical treatment. On clinical examination the ovoid-shaped mass was located on the mucosa of the right cheek, approximately 1 cm below the Stensen’s duct orifice; it was reddish-brown in color, had a hard-elastic consistency, and bled easily during manipulation (Fig 1). The neoplasm, which had been present for about 5 years, slowly increased in volume reaching the dimensions reported above, thus causing dysphagia and bleeding due to the presence of superficial microlesions induced by chewing. The tumor was removed surgically with an easy enucleation from healthy cheek tissues. After the excision the mass measured 7.5 5 4 cm. (Fig 2). The patient was discharged after 3 days. Twenty-four months later, no recurrence was detected. Microscopically, the lesion did not appear to be encapsulated, however, it was well-demarcated (Fig 3),
