RESUMO

Pleomorphic adenoma (PA), originally called mixed tumour, is the most common neoplasm of the salivary glands. It is usually a benign, slow-growing and well-circumscribed tumour. However, PA may occasionally give rise to metastases that usually occur after a previous recurrence. These tumours display benign histological features in both primary tumours and metastases. Such tumours have been termed metastatic PA or metastatic mixed tumours. We report a case of metastatic PA of the submandibular gland with metastasis to the cervical lymph nodes.

RESUMO

Introduction : L'inhalation du corps etranger (Ce) est un accident domestique grave survenant surtout chez le petit enfant et peut occasionner une detresse respiratoire aigue necessitant une prise en charge therapeutique urgente. Le but de notre travail est d'analyser les aspects cliniques et therapeutique des Ce tracheo-bronchiques vus en urgence. Patients et methode ; etude retrospective regroupant 107 enfants ages de moins de 15 ans; presentant une symptomatologie respiratoire aigue (= 3 jours); admis au service d'OrL; CHU Farhat Hached Sousse; pour bronchoscopie rigide devant la suspicion d'inhalation d'un Ce; entre janvier 2000 et Decembre 2011. Resultats : nous avons retrouve en moyenne 9 cas de Ce par an. L'age moyen de nos patients etait de 30 mois avec des extremes allant de 6 mois a 15 ans. Parmi ces enfants; 70 avaient un age compris entre 1 et 3 ans. Le syndrome de penetration a ete retrouve dans 77;6 des cas. Le symptome le plus frequent etait une toux dans 74;8 des cas. Deux patients ont presente un etat d'asphyxie aigue. La diminution du murmure vesiculaire a ete retrouvee dans 39;2 des cas. L'examen clinique et la radiographie pulmonaire etaient normaux dans 24;3 des cas. Un Ce radio-opaque a ete retrouve dans 5 cas. L'emphyseme obstructif unilateral a ete retrouve dans 39;2 des cas. Les grains de tournesol etaient les plus frequents; notes dans 26;2 des cas; suivis par les cacahuetes dans 15 des cas. Le Ce etait bronchique dans la majorite des cas avec une predominance du cote droit; 62;6 contre 33;7 du cote gauche. La bronchoscopie rigide a ete pratiquee pour l'extraction des Ce chez tous nos patients. Il n'y avait pas de deces dans notre serie. Conclusion : L'inhalation d'un Ce chez l'enfant est une pathologie grave qui engage le pronostic vital. Il faut l'evoquer devant meme des anomalies non specifiques et une endoscopie bronchique doit etre faite au moindre doute

RESUMO

Magnesium-substituted fluorapatite powders were synthesized by hydrothermal method, and their sintering behavior was investigated by dilatometry in the temperature range 25-1100°C. Analysis of the obtained powders by X-ray diffraction and (31)P NMR spectroscopy showed that the powders consisted of a single apatite phase and no amorphous phase has been formed. Compared to pure fluorapatite, the shrinkage of the substituted samples occurred in two steps and the temperature at which the sintering rate was maximum is lower. In addition, the shrinkage was interrupted by an expansion of the samples due to the formation of a liquid phase. The latter phase led to the crystallization of needle-crystals by a dissolution-diffusion-reprecipitation process.

RESUMO

OBJECTIVE: This retrospective study aims to establish an algorithm indicating a bronchoscopy, based on clinical and radiological criteria predictive of the presence of a foreign body (FB), in children with prolonged respiratory symptoms and no history of foreign body aspiration (FBA); to establish a study of these criteria and to compare the clinical, radiological and broncoscopic findings in such cases. METHODS: We chose to review the records of 73 children (age < or = 15 years) with prolonged respiratory symptoms (for at least 15 days) and no history of FBA who underwent bronchoscopy at our institution between 1996 and 2005. RESULTS: The mean age was 3 years and 2 months, the majority of the patients were between 1 and 3 years of age (56%), 59% of the patients were boys and the mean of evolution of symptoms before the broncoscopy was 3 months and 3 weeks. We found a foreign body (FB) in 17 cases (23.2%). The FBs were in 88.2% of the cases of vegetable origin. A granulation tissue was associated in 47% of positive bronchoscopies. There were no complications related to bronchoscopy. The clinical and the radiological findings were no specific of FBs. CONCLUSION: Bronchoscopy must be indicated in suspected cases of FBA to prevent delayed diagnosis and pulmonary sequelae. The clinical and radiological findings may help the clinician to indicate it.

RESUMO

Nasal natural killer (NK)/T-cell lymphoma is an uncommon disease, and only a few paediatric cases are found in the literature. We report 2 cases of NK/T-cell lymphoma occurring in children. The primary site was the the nasal cavity in the first case (5-year-old girl) and the tonsil in the second case (4-year-old boy). Histological study showed a polymorphic neoplastic infiltrate with an angioinvasive pattern and T-cell phenotype. Ebstein-barr virus infection was established by in situ hybridization. Both underwent an aggressive chemotherapy regimen. The outcome was favorable for the 4-year old boy; however, the 5-year-old girl died two months after diagnosis.

RESUMO

OBJECTIVE: Carcinoid tumors are among the exceptional neoplasms of the larynx. The literature is reviewed and the problems with diagnosis and management of this rare tumor are discussed. METHODS: The authors report a case of a carcinoid tumor of the larynx. RESULTS: This paper describes the case of a well-differentiated carcinoid tumor of the aryepiglottic fold in a 59-year-old woman who presented with hoarseness lasting eight months. After surgical excision, the patient developed recurrence of the disease 14 years later. CONCLUSION: Carcinoid tumors require accurate diagnosis because of their varied clinical behavior and prognosis. The typical carcinoid treatment of choice is conservative surgery.

RESUMO

The cryptococcal infection of the larynx is uncommon. We present a case of a 65-year-old woman who was seen because of chronic hoarseness. Direct laryngoscopy revealed an infected lesion of the laryngeal vestibule. Histologic examination showed yeasts surrounding by capsules allowing a diagnosis of laryngeal infection by cryptococcus neoformans. The patient had also meningitis and pulmonary localisation. We have undergone a risk factors research and this results in finding out that HIV serology was positive. She received a treatment with amphotericin B followed by fluconazole during 6 months with complete recovery of her laryngeal infection. The patient died 11 months after the AIDS diagnostic.

RESUMO

INTRODUCTION: Extra-nodal T lymphomas of the ear, nose, and throat (ENT) are unusual in Western countries, with differential diagnosis from other destructive and necrotizing lesions of the sino-nasal tract often difficult. MATERIAL AND METHODS: Eleven cases of extra-nodal lymphomas of the upper aerodigestive tract tract managed in the ENT department of F. Hached hospital in Sousse, Tunisia, were retrieved over a 10-year period (1995-2004). The aim of our study was to report the clinical and pathological data and the outcome for each patient. RESULTS: The median age of patients was 41-years. The most frequent site of involvement was the nasal cavity. Clinically, the symptoms were not specific. Histological examination identified two cases of T/NK lymphoma and nine cases of T-lymphoma not otherwise specified. Immunohistochemistry and in situ hybridization techniques positively detected Epstein-Barr virus in tumoral cells, in seven cases. Tumor staging, in 10 patients, found distant metastasis in three. Nine patients underwent the following treatment: exclusive radiotherapy (one patient), radiochemotherapy (three patients), and exclusive polychemotherapy (five patients). The two remaining patients had no treatment because of a rapidly unfavorable progression. After a median follow-up of 11-months, clinical outcome consisted in death in seven patients and remission in three patients; one patient was lost of follow-up. CONCLUSION: Extra-nodal lymphomas of the ORL tract are rare in Tunisia. Clinical presentation is not specific, depending on the lymphoma location. Diagnosis relies on clinical presentation and immunophenotypic and molecular characteristics; morphological features are not specific. These are aggressive lymphomas, often requiring multidisciplinary management.

RESUMO

Aspergillus mastoiditis is a very rare condition usually observed in immunocompromised patients. Masked mastoiditis is defined as a subclinical infectious inflammatory process of the mucosal lining and bony structures of the mastoid air cells with intact tympanic membranes. To our knowledge, our report of a masked Aspergillus mastoiditis occurring in a 71-year-old diabetic woman is only the second case of masked mastoiditis in the literature. Aggressive medical and surgical management are necessary to avoid a fatal outcome from this invasive infection.

RESUMO

OBJECTIVES: To describe a case of mucoepidermoid carcinoma of the parotid gland that caused obstruction of a salivary gland duct and manifested as a parotid retention cyst. PATIENT AND METHODS: A 21-year-old woman presented with a 5-cm cystic swelling in her left parotid region. Ultrasound examination and a computerized tomography scan showed a clearly outlined parotid cyst. Through a conventional parotidectomy incision, the cyst was excised with parotid gland tissue around the lesion. The patient had an uncomplicated recovery. RESULTS: Histopathological examination of the resected parotidectomy material showed a parotid retention cyst and a mucoepidermoid carcinoma measuring 5mm in diameter. CONCLUSION: Among acquired cysts of the parotid gland, retention cysts are the most frequent. They may be the presenting symptom in patients with occult cancer of the parotid. In this case report, a mucoepidermoid carcinoma played a significant role in the obstruction of a salivary gland duct and caused a parotid retention cyst. Thus, a wide excision of the parotid retention cyst is necessary, as is a careful review of the histology searching for malignant lesion.

RESUMO

Nasopharyngeal angiofibroma is a locally aggressive, although histologically benign, vascular neoplasm. This neoplasm accounts for 0.05% of head and neck tumours and affects almost exclusively male adolescents. Surgery is considered as the primary treatment of nasopharyngeal angiofibroma. Other treatment modalities such as radiotherapy and chemotherapy are still recommended for intracranial extension involving the cavernous sinus or the internal carotid artery. We report a rare case of nasopharyngeal angiofibroma, further complicated with a Kennedy syndrome in a 34 year-old women. The treatment consisted in a chemotherapy (adriamycine, decarbazine) followed by radiotherapy. We discuss the relevance and outcome of the association chemotherapy-radiotherapy in the treatment of nasopharyngeal angiofibromas with a consistent intracranial extension (stage III B of Arch Otolaryngol Head Neck Surg 122 (2003) 122-129).

RESUMO

Objectif : Rappeler les principales caracteristiques etiopathogeniques des stenoses tracheales post-intubation; preciser le bilan preoperatoire et discuter les differentes modalites therapeutiques. Materiel et methodes : Notre travail porte sur une etude retrospective de vingt huit stenoses tracheales cicatricielles traitees de 1987 a 2003 au service d'ORL et de chirurgie cervico-faciale du CHU Farhat Hached de Sousse. Resultats : Elles sont toutes acquises; secondaires a une intubation et/ou a une tracheotomie. Les resultats de notre travail montrent le role primordial du traitement medical et endoscopique. Cependant; le meilleur traitement des stenoses tracheales reste le traitement chirurgical base sur la resection anastomose tracheale dont on a precise les indications et evalue les resultats; juges bons avec 89de cas favorables. Conclusion : Nos resultats montrent que le traitement endoscopique des STPI peut etre considere comme un traitement de premiere ligne. Les stenoses complexes et resistantes au traitement endoscopique relevent d'un traitement chirurgical

RESUMO

Introduction : Les tumeurs parotidiennes de l'enfant sont rares. Plusieurs types histologiques peuvent etre rencontres et rappellent souvent ceux de l'adulte. But : Analyser les particularites epidemiologiques; cliniques et therapeutiques des tumeurs parotidiennes chez l'enfant. Materiel et methodes : Il s'agit d'une etude retrospective; portant sur 13 observations de tumeurs parotidiennes de l'enfant colligees sur une periode de 23 ans de Janvier 1985 a Decembre 2007. Resultats : Nos malades se repartissaient en 8 filles et 5 garcons. L'age moyen etait de 11 ans. Notre serie avait comporte 12 cas (92;3) de tumeurs benignes et un cas (7;7) de tumeur maligne. Tous nos malades ont eu un traitement chirurgical. L'examen histologique definitif a conclu a un adenome pleomorphe dans 5 cas; un oncocytome dans un cas. Deux malades etaient porteurs d'une tumeur vasculaire; un malade d'une tumeur nerveuse; deux de kystes lymphoepitheliaux; un malade d'un kyste hydatique et un patient d'un carcinome mucoepidermoide. L'evolution a ete marquee par l'absence de recidive tumorale avec un recul variant entre 8 mois et 6 ans pour tous nos malades. Conclusion : Bien que les tumefactions parotidiennes soient rares chez l'enfant; elles representent une grande variete de diagnostics histologiques y compris des tumeurs malignes

RESUMO

L'otite externe necrosante est une pathologie grave qui pose de plus en plus de difficultes dans la prise en charge therapeutique. Nous rapportons dans ce travail une observation d'otite externe necrosante compliquee d'une paralysie faciale qui avait resiste au traitement medical et chirurgical bien conduits. L'adjonction de l'oxygenotherapie hyperbare comme traitement complementaire a permis une regression des signes cliniques et une guerison de l'infection. Il s'agissait du premier cas d'otite externe necrosante ayant beneficie en mars 1996 de l'oxygenotherapie hyperbare en Tunisie. A travers cette observation; nous discutons l'indication de l'oxygenotherapie hyperbare dans le traitement de l'otite externe necrosante

RESUMO

Objectifs: Rappeler les caracteristiques cliniques; paracliniques; et les modalites therapeutiques adaptees devant des paragangliomes bilateraux. Methodes: Nous rapportons deux observations de paragangliomes bilateraux; l'un tympano-jugulaire bilateral et l'autre cervical (carotidien et vagal); colligees durant une periode de 22 ans (1985-2007). Nos deux patients avaient eu un examen clinique complet un bilan radiologique et biologique. Resultats: Notre premier malade a eu une radiotherapie exclusive; le deuxieme a eu une exerese chirurgicale complete de la tumeur vagale et on a opte pour une surveillance de la tumeur controlaterale. Pour nos deux patients l'evolution etait favorable marquee par une stabilisation tumorale. Conclusion: Les paragangliomes cervico-cephaliques bilateraux sont des formes cliniques rarement observees. Le diagnostic positif repose sur l'imagerie. L'attitude therapeutique n'est pas univoque et doit etre adaptee en fonction du siege de la tumeur et du bilan d'extension locoregional

RESUMO

But : Nous illustrons un cas de thrombophlebite du sinus caverneux compliquant une oto-mastoidite. Nous etudions a la lumiere de la litterature les difficultes diagnostiques et l'importance de la mise en oeuvre d'un traitement precoce et adapte afin d'eviter les sequelles ulterieures. Observation : Il s'agit d'un enfant age de 14 ans; qui avait presente une exophtalmie avec oedeme palpebral bilateral et une baisse de l'acuite visuelle d'aggravation progressive au decours d'un episode otitique. L'examen avait objective uneparalysie faciale peripherique droite et a l'otoscopie un tympan droit bombe congestif. La TDM avait mis en evidence une thrombophlebite du sinus caverneux associee a un abces cerebral et a un abces retropharynge avec une oto-mastoidite homolaterale. Le malade a ete traite par une antibiotherapie a large spectre associee a une heparinothe-rapie; avec mastoidectomie droite et drainage de l'abces retro-pharynge. L'evolution a ete marquee par la regression totale de la paralysie faciale; avec repermeabilisation du sinus caverneux et disparition totale de l'abces temporal au controle scannographique. Le patient a garde comme seule sequelle une cecite mono oculaire gauche.Conclusion : La thrombophlebite du sinus caverneux est une affection rare; surtout dans son origine otogene elle doit etre diagnostiquee et traitee le plutot possible; afin de prevenir les sequelles ou d'obtenir la regression de ces dernieres. Le traitement doit associer une antibiotherapie a large spectre; les anticoagulants et un drainage chirurgical approprie du foyer septique

RESUMO

But : Les tumeurs a cellules oncocytaires de la thyroide (TOT) ont donne jusqu'a ces dernieres annees de nombreuses controverses; du fait des difficultes a differencier les tumeurs benignes des tumeurs malignes; entrainant des attitudes therapeutiques divergentes. L'objectif de cette etude est de voir a travers une revue de litterature les aspects cliniques et pathologiques particuliers aux tumeurs oncocytaires de la thyroide et d'essayer de reunir les elements cliniques et anatomopathologiques pouvant predire l'aspect malin de ces tumeurs. Methodes : Il s'agit d'une etude retrospective menee sur une periode de 19 ans etalee de janvier 1988 a decembre 2006; pendant laquelle nous avons collige 25 cas de tumeurs oncocytaires de la thyroide. La circonstance de decouverte etait un nodule thyroidien pour tous les patients. Resultats : Notre travail repose sur une serie de 25 tumeurs oncocytaires de la thyroide; dont 3 cancers oncocytaires (12). Ces tumeurs representent 1;2 des tumeurs thyroidiennes operees durant la meme periode. L'age moyen des patients ayant eu un carcinome oncocytaire etait de 65 ans; la taille moyenne de ces carcinomes etait de 4 cm. Le traitement a consiste en une loboisthmec- tomie pour les adenomes et en une thyroidectomie totale associee a un curage ganglionnaire cervical suivi d'une iratherapie pour les carcinomes. Une seule patiente ayant presente un carcinome oncocytaire a developpe une metastase a distance. L'evolution etait favorable chez tous les autres patients avec recul variable de 9 mois a 22 ans avec une moyenne de 5 ans. Conclusion : Les tumeurs oncocytaires de la thyroide sont reconnues a la lumiere des travaux recents comme une entite anatomo-clinique particuliere; se differenciant des tumeurs vesiculaires (auxquelles elles ont ete longtemps assimilees) par une evolution plus pejorative et par une insensibilite a l'iode radioactif avec une frequence accrue de metastases pour les carcinomes

RESUMO

La mastoïdite masquée (MM) se définit comme un état inflammatoire latent de la muqueuse et de l'os mastoïdien avecun tympan normal. Elle est révélée par une complication généralement endocrânienne. Le traitement est une mastoïdectomie associée à une antibiothérapie intraveineuse.Nous rapportons deux observations de mastoïdites masquées dont le diagnostic a été évoqué par l'examen tomodensitométrique qui a rattaché les complications endocrâniennes à leur origine mastoïdienne. Le but de notre travail est de discuter les circonstances diagnostiques, les investigations paracliniques et le traitementdes mastoïdites masquées
