Condylar intramedullary intraosseous lipoma : contribution of a new case and review of the literature

2017

Background Lipoma is the most common benign tumour of the human body, being intraosseous involvement very rare. Just 1 to 4% of all cases of lipoma are located in the oral cavity, only 0.1% being intraosseous. The jaw is its most uncommon bone location. Etiology of intraosseous lipoma (IOL) is unknown, although several theories have been proposed. Usually asymptomatic, the symptoms, when present, will depend on its location and size. Its origin may be intraosseous or juxtacortical. A biopsy is essential for diagnosis, and definitive treatment involves resection or curettage of the lesion. The aim of this paper is to present a new case of intramedullary intraosseous lipoma of the mandible wi…

Tumours of Nasal Septum: A Retrospective Study of 32 Patients

2022

Objective: Tumours of the nasal septum are a rare and heterogeneous group of lesions in the sinonasal tract. The management of the different lesions of this site is debated. The aim of this study is to share our experience on a rare clinical condition and stimulate other centres to publish theirs. Methods: We retrospectively analysed the databases of sinonasal tumours treated at the Sections of Otolaryngology (ENT) of two University Hospitals (Palermo and Genova) between 2012 and 2020. Results: From the two databases, a cohort of 32 patients with tumours of nasal septum were selected. All patients underwent an endoscopic examination. Large tumours underwent preoperative computed tomography …

A large ameloblastic fibro-odontoma of the right mandible

2007

The ameloblastic fibro-odontoma is a rare mixed odontogenic tumor. It occurs predominantly in children and young adults with no sex predilection and locates most often in the posterior segment of the mandible. A painless swelling is the most common clinical sign. Radiologically, ameloblastic fibro-odontoma shows a circumscribed radiolucency, which contains radio-opaque foci of various sizes and shapes. Histological examination reveals a fibrous soft tissue, islands of odontogenic epithelium and a disordered mixture of dental tissues. The tumor produces enamel or enamel matrix, dentin and cementum. The treatment of ameloblastic fibro-odontomas usually consists of enucleation or surgical cure…

Neurofibroma plexiforme en mucosa yugal: presentación de un caso clínico

2004

Presentamos un caso clínico de neurofibroma plexiforme localizado en región geniana, a nivel submucoso. Su interés radica en que, a pesar de ser el tumor de origen neurógeno más frecuente, es una entidad poco habitual y que rara vez se localiza a nivel intraoral. Por otra parte, la variedad plexiforme es todavía menos frecuente. Desde el punto de vista clínico, se manifiestan como lesiones anodinas, con escasa sintomatología, que cuando aparece es derivada de la compresión nerviosa. En nuestro caso el tumor era asintomático salvo por el tamaño. Radiológicamente no existe una imagen definitiva. Tiene relación con determinados síndromes poliglandulares y facomatosis. El tratamiento es básicam…
