Introduction: Psoriasis is a chronic inflammatory skin disease that typically affects the extremities, trunk, scalp, and nails. Psoriatic cheilitis as an exclusive presentation is very rare and to our knowledge, only 6 cases have been reported to date. The absence of cutaneous lesions causes diagnostic difficulties that can result in misdiagnosis and inadequate treatment. Observation: We reported the case of a 21-year-old woman with a seven years history of scaly plaques of the vermillion of the lips as the only disease manifestation. Her cheilitis was associated with significant psychiatric morbidity. Oral biopsy showed a psoriasiform pattern. Local applications of betamethasone was proposed. Discussion: Although lip psoriasis is extremely rare, it can be the sole presentation of psoriasis even in the absence of accompanying skin lesions, other oral manifestations or a family history of psoriasis. Conclusion: Lip psoriasis should be considered in the differential diagnosis of chronic or recurrent treatment-resistant labial lesions.
-Malignant lesions of the jaw-bones may mimic odontogenic infections and other disease conditions in the oral cavity in presentation, leading to late diagnosis by the unwary clinician. The purpose of this paper is to illustrate clinical features and radiographic appearance that should make the dentist thinking in a diagnosis of a malignant tumour of the jaw. The authors present 3 cases of malignancies in the jawbones and discuss the diagnostic lessons from each one.
Introduction: Lichen planus is an inflammatory mucocutaneous dermatosis involving skin, appendages and mucosa. Oral mucosa is the most commonly involved in all its sites, rarely the lips especially when isolated. The aim was to conduct a literature review about isolated lichen planus of the lips and reporting two case reports of this lesion in order to highlight epidemiologic, clinical and histological features and therapeutic modalities of this lesion. Observations: Case report 1: a 34-year-old diabetic male patient consulted for an erosive, crusted and hemorrhagic cheilitis of the lower lip. Clinical and histological examination led to the diagnosis of isolated lichen planus of the lips. Case report 2: a 33-year-old female patient was referred from dermatology department for biopsy of chronic cheilitis of the lower lip. Clinical and histological examination confirmed the diagnosis of isolated lichen planus of the lips. Discussion: The review based on 34 case reports of isolated lichen planus of the lips, in addition to literature data confirmed that it is a benign rare lesion affecting mostly male patients having middle age with preponderance of the lower lip, its erosive form is the most frequent and it presents a favorable healing with topical treatment particularly corticosteroids.
Résumé -Le rôle prophylactique des antiseptiques appartenant à deux familles différentes, le digluconate de chlorhexidine à 0,12 % et l'hypochlorite de sodium à 0,5 %, a été étudié dans une étude prospective randomisée. La population était composée de trois groupes dont deux ont utilisé l'un des deux bains de bouche 5 jours avant l'extraction de dents de sagesse mandibulaires enclavées, l'autre groupe a servi de témoin. L'objectif était de déterminer l'effet des deux produits dans la prévention des complications inflammatoires et infectieuses postextractionnelles. Les résultats ont été statistiquement assez concluants et l'utilisation de ces deux bains de bouche présente un intérêt, surtout dans la réduction du taux d'alvéolites, et l'amélioration de la cicatrisation après les extractions non chirurgicales des dents de sagesse mandibulaires enclavées.Abstract -Interest of chlorhexidine 0.12% and sodium hypochlorite 0.5% in preoperative phase: comparative study. In a randomized prospective study, the prophylactic role of two antiseptics belonging to two different families, chlorhexidine digluconate 0.12% and sodium hypochlorite 0.5%, was studied. The population included three groups, of which two have used one of the two mouthwashes 5 days before extraction of the partially erupted mandibular third molar and the third group was a control one. The objective was to determine the effect of two antiseptic products regarding the prevention of post extraction infectious and inflammatory complications. Results were statistically conclusive and the use of these two mouthwashes could be of a great interest mainly in reducing the rate of alveolitis and improving of the postoperative healing for non-surgical extractions of partially erupted mandibular wisdom teeth.
Résumé -Les lithiases parotidiennes sont beaucoup moins fréquentes que les lithiases submandibulaires et elles ont le plus souvent une localisation canalaire. La difficulté thérapeutique découle de leur localisation souvent postérieure qui ne permet pas d'utiliser une voie d'abord endo-buccale. On rapporte le cas d'un patient qui présentait un tableau de parotidite chronique rétentionnelle évoluant depuis 10 ans et dont le diagnostic fut retardé car la lithiase n'était pas visible sur l'échographie. L'examen tomodensitométrique a révélé la présence d'une lithiase de 8 mm de long situé dans la courbure massétérine du canal parotidien. Son ablation a pu être réalisée par voie endo-orale.Abstract -Oral access of a voluminous sialolithiasis in the Stensen's duct curvature: a case report. The parotid sialolithiasis are far less common than submandibular ones and they are located most often in the duct. The difficulty arises from the treatment of posterior location stones which are not accessible to the intraoral access. We report the case of a patient who presented with a chronic obstructive parotitis dating back 10 years misdiagnosed because the ultrasound didn't show the presence of a sialolith. A computed tomography scan reveled the presence of a 8 mm sialolith located at the bend of the masseter parotid duct. The sialolithiasis has been removed successfully by intraoral access.Les lithiases parotidiennes sont beaucoup moins fréquentes que les lithiases submandibulaires, et de diagnostic clinique et radiologique moins aisé. En conséquence, elles sont parfois méconnues. Devant un tableau de rétention salivaire (colique, hernie), c'est la découverte de la lithiase qui permet de confirmer le diagnostic. L'indication des examens paracliniques pour la mettre en évidence a sensiblement évolué depuis quelques années. Bien que de nombreux auteurs proposent une nouvelle approche thérapeutique peu invasise, l'abord chirurgical classique reste le traitement de référence, surtout pour les lithiases facilement accessibles.On rapporte un cas de lithiase siégeant dans la courbure massétérine du canal parotidien qui a pu être traitée par voie endobuccale.
