Osteoma is a benign, slow-growing tumor characterized by proliferation of compact or cancellous bone. Solitary osteomas are classified as peripheral, central, or extraskeletal. Peripheral osteomas of the oral cavity are unusual and the maxilla is rarely affected. They manifest as asymptomatic, fixed tumors of bony-hard consistency that may be sessile or pedunculated. Radiographically, a well-circumscribed round or oval radiopaque mass is seen that is microscopically composed of cancellous or trabecular bone. A case of a compact, peripheral osteoma arising from the buccal plate of the alveolar ridge of the maxilla in a 64-year-old patient is presented. According to our literature review, this is the seventh case reported in the maxillary ridge.
Whether or not this property to produce significant amounts of bone can be associated with a different biological behavior for this specific variant of OM remains to be proved with the study of more similar cases.
Aspergillus species are commonly found in the soil and decaying organic matter. The spores can be typically inhaled or ingested, yet disease due to tissue invasion is rarely seen in the immunocompetent host. In the immunocompromised patient, there has been an increased incidence of invasive aspergillosis in the last 20 years. Invasive aspergillosis of the maxillary sinus with orbital and cranial spread can be lethal, therefore, necessitates early diagnosis and prompt treatment. The predilection of Aspergillus for infiltration of blood vessels can result in serious ocular complications which can lead to loss of vision. We present the case of an uncontrolled diabetic patient with invasive maxillary sinus aspergillosis and extension to the orbital contents. Our purpose was to emphasize the need of early recognition and prompt initiation of combined antifungal treatment and surgical intervention with the intent to preserve the involved vital structures.
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.
