[Harlequin syndrome in a melanoderm patient]. / Syndrome d'Arlequin chez un patient mélanoderme.

INTRODUCTION: Harlequin's syndrome is a neurological disorder due to a dysfunction of the sympathetic innervation of the face. It has been rarely reported in the literature. The authors report one case occurring in a melanoderm patient. OBSERVATION: A 38-year-old melanoderm man, without any history of surgery or neck trauma, consulted for a strictly right unilateral facial hyperhidrosis. Clinical and radiological investigations concluded to an idiopathic Harlequin's syndrome. Therapeutic abstention was proposed because of non-invalidating symptoms. DISCUSSION: Harlequin's syndrome is a rare sudoral and vaso-motor disorder. On dark skin, flush and erythrosis may be subtle and the diagnosis less obvious. Etiologies are varied but essentially idiopathic. Its association with others dysautonomic facial syndromes is possible. Main differential diagnosis is the Frey's syndrome. Treatment is not clearly codified.

[Sinonasal mucormycosis revealed by a necrotic velar ulceration]. / Mucormycose rhinosinusienne révélée par une ulcération nécrotique vélopalatine.

INTRODUCTION: Mucormycosis is a deep mycosis which has been spreading out in recent years. It is still poorly understood and poorly described in sub-Saharan Africa. The authors report a case of sinonasal localization, of fatal evolution and late diagnosis in a young child. OBSERVATION: It is about a 13-year-old child suffering from chronic rhinosinus syndrome for two years. He was observed in stomatology for a necrotic velar ulceration that have occurred for three months. The clinical, radiological and histological explorations were in favor of a sinonasal mucormycosis. The administration of amphotericin B and the surgical treatment did not slow down the fatal evolution. CONCLUSION: Mucormycosis should not be dealt with any diagnostic error and no therapeutic improvisation. It has to be thought about when dealing with a rhinosinusal syndrome with cleft ulceration.

[Diagnostic and therapeutic aspects of parotid tumors in the Maxillofacial Surgery Department of the University Hospital Center in Treichville, Abidjan]. / Les aspects diagnostiques et thérapeutiques des tumeurs parotidiennes en chirurgie maxillo-faciale au CHU de Treichville Abidjan.

INTRODUCTION: Taking charge of parotid tumors in an African setting is difficult because of the weakness of the technical, delayed consultation, treatment of traditional healers, tumor volume, secondary infection and ulceration of some of them. OBJECTIVE: Identify the epidemiological, clinical, evolutive and therapeutic in order to propose an adapted scheme to the management of these tumors in our African conditions. MATERIALS AND METHODS: This is a retrospective study of 38 patients with parotid tumors operated and hospitalized in the department of stomatology and maxillofacial surgery university hospital of Treichville (Abidjan), during the period from January 2005 to December 2009 included, so a period of 5 years. RESULTS: The study involved 21 (55.3%) men for 17 (44.7%) women aged between 8 and 75 years came to 76.31% for parotid tumor. In 55.26% patients consulted between 1 and 5 years. Clinically: general condition was preserved in 91.1%, tumor size ranged between 5 and 10 cm in 60.53%, they were in the form of nodules in 78.9%, were covered with healthy skin in 78.95%, appeared as isolated tumor in 72.06%. Ultrasound examination was the most paraclinical exam used (65.79%). The tumors were benign in 76.3% dominated by pleomorphic adenoma (63.2%). The most common malignant tumor was muco epidermoid carcinoma (7.9%). Exo-facial parotidectomy was the most common technique used (60.52%). The rate of patient follow-up at 2 years was 5.26%. CONCLUSION: Social and cultural conditions of the management of tumors and lack of technical platform lead us to propose the total parotidectomy for a better cure rate of patients.

[Diagnostic and surgical approach to an hourglass-shaped nasopalatine glioma in an infant]. / Approche diagnostique et chirurgicale d'un gliome naso-palatin "en sablier" chez un nourrisson.

The authors report a case of glioma nasopalatine Multifoil in wallet, location-intra nasal and palatal left. The nasal glioma is a rare congenital malformation presenting as a nasal mass composed of neuroglial tissue heteropias resulting from an abnormality in embryonic development. It is a benign tumor that fits into the nosology of the masses of the midline. This abnormality arises primarily a diagnostic problem because often mistaken for a meningo-encephalocele or a nasal dermoid cyst. Localization nose and palate, an hourglass, is extremely rare if not exceptional; The computed tomography (CT) has enabled the accurate assessment of injury and has guided the choice of surgical technique. The resection was done successfully without recurrence. Histology examination of the surgical specimen confirmed the nature of astrocytic neuroglial tumor. The location of the tumor pedide palate to that of the left nostril is special and especially histological diagnosis of this congenital malformation.
