We report the case of a 04-day old female neonate, with a teratoma of the nasopharyngeal area. Examination showed a polypoid mass protruding from the nasopharynx measuring 3 x 2 x 2 cm, covered on one side with numerous fine and coarse hair. Surgical excision of the mass was performed under general anesthesia on day 4 after birth. Pathology revealed a well differentiated mature teratoma. The patient had no complication in the postoperative period.

Elle est la consequence d'un defaut de migration du tubercule thyroidien depuis la base de la langue, lieu de son apparition, jusqu'a sa position definitive pretracheale. Son incidence est estimee a 1 pour 100 000 (1, 2). L'ectopie thyroidienne intratracheale est exceptionnelle. Elle represente moins de 7% des tumeurs tracheales (1, 2). Le goitre ectopique intratracheal est encore plus rare. Sa decouverte peut etre faite a tout âge. Il est beaucoup plus frequent chez la femme. Le tableau clinique est constitue essentiellement d'un stridor et de dyspnee inspiratoire. L'imagerie permet de faire le diagnostic et d'orienter l'attitude therapeutique.

Here we describe an extremely rare case of a 19-year-old male patient with a brown tumor localised in the maxilla and mandibular due to secondary hyperparathyroidism compromising mastication, phonation and social ease of the patient. An early diagnosis and a timely parathyroidectomy in a medically resistant hyperparathyroidism are an optimal option to control the growth of the bony lesion

Due to its rarity and its similarity to other tumors skull base lymphoma remains a diagnostic challenge. We present a 3-year-old previously healthy boy presented with blindness and exophtalmos revealing a primary skull base lymphoma. The clinical and the radiological features of the lesion have been described as well as the pathologic findings. Lymphoma, although uncommon, should be included in the differential diagnosis of such neoplasms of the skull base. Early diagnosis and treatment as prompt management are crucial for both a visual and vital prognosis.

Its location outside the main salivary glands defines the pleomorphic adenoma of atypical location. The aim of this study is to analyze the clinical, diagnostical and therapeutical features of this tumor at atypical locations through seven observations. This work is a retrospective study. It has for objective to present 7 cases of pleomorphic adenoma developed on minor salivary glands diagnosed in Otolaryngology Head and Neck surgery department in Mohammed VI University hospital, between December 2003 and December 2010. We had 3 cases of pleomorphic adenoma of the hard palate and 1 case of each soft palate, superior lip, lower eyelid and nasal septum. The sex ratio woman/ man was 133. The symptomatology was variable according to the location of the tumor. The tumoral syndrome was constant. The diagnosis of pleomorphic adenoma was suspected at the clinical stage in 3 cases of palatal location. The CT scan was performed...

Il correspond à la présence de pus entre le cartilage septal et son mucopérichondre et/ou l'os septal et son mucopérioste. Nous rapportons trois cas de patients pris en charge au niveau de notre structure. Nous profitons de ces nouveaux cas pour rappeler les différentes étiologies ainsi que la prise en charge qui doit être rapide et adéquate pour préserver le pronostic fonctionnel et esthétique engagé par cette affection.

Nous rapportons l'expérience du service d'Oto-rhino-laryngologie et de chirurgie cervico-faciale de l'hôpital universitaire Mohammed VI de Marrakech, dont l'objectif est d'évaluer l'implantation cochléaire et de préciser les facteurs influençant les résultats dans notre pratique. Le profil APCEI a été utilisé pour évaluer les résultats orthophoniques. Il s'agit d'une étude rétrospective étalée sur une période de 7 ans (Décembre 2007 à Décembre 2014). Durant cette période; 54 patients ont été implantés et suivient dans notre formation. Il s'agit de 30 filles et 24 garçons atteints d'une surdité sévères à profonde bilatérale, dont 48 enfants avaient une surdité pré-linguale. L'âge moyen d'implantation cochléaire pédiatrique était de 5,15 ans. L'implantation était unilatérale chez tous les patients. L'intervention était suivie par des réglages et une rééducation orthophonique régulière. L'évaluation était réalisée par la même équipe chaque mois durant les premiers 6 mois, puis tous les 6 mois. La durée moyenne de suivi était de 30,86 mois. Tous les patients ont tiré un bénéfice de leurs implants avec une variabilité interindividuelle. Les bons résultats étaient corrélés à l'implantation précoce, à un investissement parental important et au un bon suivi de la rééducation orthophonique. L'implantation cochléaire a révolutionnée la prise en charge de la surdité profonde et sévère. C'est une technique sûre, efficace lorsqu'elle s'adresse à des populations correctement sélectionnées.

Two forms are described, solitary and multicentric, the solitary type is more common and is localized mainly on the head and the neck, mandible involvement is rare. The recent observation of a patient with a myofibrome of the mandible has given the opportunity to conduct an analysis and review of the literature of this disease rarely encountered. We report a case illustrating solitary myofibroma of the mandible in a 16 year old man. The histological diagnosis was done on the identification of the spindle-shaped tumoral proliferation and the positive expression of the anti-vimentine, anti-smooth, muscle actin anti desmin. The treatment was surgical. myofibromatosis often presents as a painless, well-circumscribed, solid nodule. Imagery is very useful to assess lesion extension and for the therapeutic followup. The diagnosis is made on anatomopathological findings and immunohistochemical assessment. The treatment of the solitary myofibromatosis is primarily surgical and its prognosis is excellent contrary to the multicentric form.

The aim of this study was to report a case of giant parapharyngeal lipoma in a child and to present clinical, paraclinical, and treatment aspects. A 14-year-old child presented with a painless progressive mass on the right side of the upper neck. It was growing asymptomatically since 2 years. Cervical CT-scan and MR showed a low-density mass in the right parapharyngeal, consistent with a mass of adipose tissue origin. The mass was surgically removed via cervical-parotid approach. The fatty mass was completely excised. Histopathology confirmed it to be a lipoma. The patient has been followed up for three years, and there have been no signs of recurrence. Diagnostic orientation in parapharyngeals tumors is necessary for better care. This guidance is being facilitated through imaging advances. Their surgical approaches and complete excision depend on volumes, localizations and their proximity to neurovascular structures.

It may be found exceptionally in the upper aerodigestive tract (UADT) after consumption of spring water or water from natural wells, after swimming in still waters (lakes and dams). The author's objective was to study epidemiological, clinical, therapeutic, and evolutive aspects of this infestation. This prospective 2-year study was carried out from January 1, 2007 to December 31, 2008. We included all patients consulting at the emergency unit presenting with leeches in the UADT. Twenty patients living in rural settings were included: 16 children, mostly boys (sex ratio 3:1). All cases were recorded during the summer season, with 14 cases due to consumption of fresh water and six due to swimming in still waters. The delay between infestation and onset of symptoms ranged from 2 to 15 days. Leeches were found in the oropharynx (six cases), the nasopharynx (five cases), the hypopharynx (six cases), and the glottis (three cases). An anemia syndrome was noted in four patients. All parasites were removed. All patients were given local antiseptics and analgesics. Patients with anemia were given iron supplementation. The outcome was favorable for all patients. UADT leeches are not uncommon in Morocco. The infestation is usually observed in the summer. Symptoms vary according to UADT localization. The diagnosis should be made rapidly to prevent complications. Whatever the localization, removing the parasite is difficult. In laryngeal localizations induction general anesthesia is recommended, without intubation. Evolution after treatment is rapidly favorable, with complete disappearance of symptoms.
