A case of peripheral ossifying fibroma (POF) in the anterior mandible of a 63-year-old woman is described. The 17 x 23 x 16mm nodular mass was sessile, displaced teeth and had a non-ulcerated, pink surface. Due to the variations in radiographic, clinical and pathological appearance, initially the diagnosis of peripheral odontogenic fibroma was reached. Complex nomenclature and variation in clinical, radiological and pathological appearance of POF and similar masses is discussed.
A 64 year old female patient presented to the Accident and Emergency (A&E) department at the Royal Lancaster Infirmary (RLI) with a significant left sided jaw pain. This patient reported paraesthesia and a shooting pain radiating down her left mandible. There was also marked trismus on examination. Her medical history included a history of a previously diagnosed Squamous Cell Carcinoma (SCC) of the left soft palate. This was staged at T2N0M0 and treated with radiotherapy and chemotherapy. Following a clinical examination, special investigations via imaging were obtained prior to a formal diagnosis of pathological fracture of the left mandible following previous radiotherapy for her SCC treatment.
This case report will discuss the incidence, background, management and treatment of osteoradionecrosis (grade 3) (ORN) of the mandibular jaw bone as well as the associated pathological fractures and the detrimental effects following the use of radiotherapy to the head and neck region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
