Lymphoepithelial carcinoma of the salivary glands is a rare neoplasm that is characterized by a non-neoplastic lymphocytic infiltration associated with an epithelial proliferation. It involves mainly the parotid gland. Racial and geographical factors contribute to the pathogenesis of this tumor. We report a case of a 70-year old woman from a non-endemic area who presented with several months history of swelling in the parotid region. Magnetic resonance imaging showed a parotid mass suggestive of a pleomorphic adenoma. The diagnosis of lymphoepithelial carcinoma of the parotid gland was performed on the surgical specimen. A primitive nasopharyngeal carcinoma was ruled out by random biopsies of the nasopharynx mucosa. The Epstein-Barr virus (EBV) was absent in neoplastic cells. We insist that, even in non-endemic areas and when clinical and radiological characteristics are not suggestive of malignancy, intra-operative frozen section analysis should be used in order to ensure the appropriate treatment.
Background: Dentigerous cysts are seen as benign pathology associated with developing, unerupted teeth. Individuals affected present with slow growing expansion of the bone, straw-coloured fluid on aspiration and displacement of involved and adjacent teeth. Case Report: An 11-year-old boy was referred with a painless reddish mass of three months duration. Examination revealed mild, diffuse swelling over the left maxillary region with an erythematous, soft tissue sessile swelling intraorally. Orthopantomograph showed radiopacity over the left maxillary sinus with displaced 27, 28 crowns. Contrast computed tomography (CT) and angiography identified feeder vessels from the branches of the left internal maxillary artery. Treatment and Follow-up: Embolisation was performed initially to block the supplying artery. Enucleation of the lesion followed three days post-embolisation. A histopathological examination of the lesion was carried out once enucleation complete. A review and monitoring programme was followed at three-, six-and ninemonth intervals. Conclusion: Judicial use of contrast CT and angiography can aid accurate diagnosis of erythematous oral growths in young patients.
This clinical report describes the oral rehabilitation of a 22‐year‐old‐man diagnosed with a variant of hypoplastic amelogenesis imperfecta. The treatment approach was multi‐disciplinary, and it included the surgical procedure of Lefort I osteotomy, surgical crown lengthening, and metal‐ceramic‐fixed dental prostheses. The patient was satisfied with the esthetic and functional outcome.
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.
