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.

Il en résulte une fente palatine. Ces tumeurs, associées à la fente palatine, peuvent occasionner des troubles respiratoires et/ou des difficultés lors de l'alimentation. Deux cas sont présentés : l'un concerne un tératome du rhinopharynx, l'autre un hamartome de la langue ; tous deux étaient associés à une fente palatine. Dans les deux cas, l'évolution a été favorable après exérèse complète de la tumeur et fermeture de la fente.Key words: mouth / neoplasms / cleft palate Abstract -Congenital oral tumors and cleft palate: about 2 cases. Several congenital oral tumors may interfere with the development of the palate. In fact, these tumors that develop before the sixth week of gestation between the two palatal shelves prevent their elevation, their horizontalisation and their fusion with the nasal septum. These tumors associated to cleft palate can cause respiratory and/or feeding difficulties. Two cases of newborns presenting nasopharyngeal teratoma in the first case and tongue hamartoma in the second case, associated with cleft palate, are reported. The diagnosis was confirmed by histology. The outcome was favorable after complete resection of the tumor and cleft closure in both cases.Les tumeurs congénitales de la cavité buccale peuvent affecter le développement normal des structures adjacentes tel que le palais. En effet, les tumeurs congénitales se développant lors de la morphogenèse du palais peuvent être associée à une fente palatine. Nous rapportons, un cas de tératome du rhinopharynx et un cas d'hamartome de la langue, associés à une fente palatine. L'objectif de ce travail est de mettre en évidence la relation de cause à effet entre ces deux entités.
