Malignant degeneration of a branchial cyst: A case report.

INTRODUCTION: Malignant degeneration of a branchial cyst is rare (Thompson, 1997). It varies from 4% to 22% (Unal et al., 2005). CASE REPORT: A74-year-old man presented to our department with a left painless upper neck mass which was excised and histopathology revealed squamous cell carcinoma in a cystic lesion. The appropriate clinical tests and imaging were performed to determine the possible presence of a primary tumor. No primary carcinoma was found. This finding suggests that this was a malignant degeneration of a branchial cyst. The patient was treated with adjuvant radiotherapy and followed up over a 2-year-period and no recurrence was found. DISCUSSION: The development of an epidermoid carcinoma in situ in the amygdaloid cyst wall is a very rare entity. The challenge is to be able to distinguish between cystic metastasis of squamous cell carcinoma of the aerodigestive tract and a primary epidermoid carcinoma developed in the wall of an amygdaloid cyst. Martin and Khafif proposed some criteria to confirm the diagnosis of branchiogenic carcinoma.

Metastasizing pleomorphic adenoma of the submandibular gland: a case report.

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.

Les corps etrangers tracheobronchiques a propos de 107 cas

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

Sternocleidomastoid pseudotumor of infancy: a report of thirteen cases.

UNLABELLED: Stemocleidomastoid tumor of infancy (SCMTI) is a rare cause of benign neck masses in neonates and infants. It has to be differentiated from other congenital space-occupying lesions in the cervical region. PATIENTS AND METHODS: The files of 13 infants with a mean age of 6 weeks, presenting with a lateral neck mass at Sahloul University Hospital in Sousse (Tunisia) between 2007 and 2009 were retrospectively studied. All of them underwent physical and ultrasonographic examination. MRI was performed in only one case. RESULTS: Ultrasonography (US) showed a soft tissue mass of sternocleidomastoid muscle (SCMM), or a homogenously enlarged muscle without any focal mass. MRI revealed a fusiform enlarged muscle. Diagnosis of SCMTI was established in all cases. Conservative treatment was recommended in all cases with physiotherapy in 2 cases. CONCLUSION: US is the best imaging modality for the diagnosis of SCMTI and the first one to be performed. Additional diagnostic imaging modalities are unnecessary in most of the cases.

[Parotid retention cyst revealing a mucoepidermoid carcinoma]. / Kyste parotidien rétentionnel révélateur d'un carcinome mucoépidermoïde.

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.

Stenose tracheale post-intubation

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

Paragangliome bilateral : a propos de deux observations

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

[Contribution of endoscopic laser coagulation in the treatment of multicentric sinonasal inverted papilloma. A case report]. / Place du traitement endoscopique au laser du papillome inversé naso-sinusien multifocal. A propos d'une observation.

OBJECTIVE: To describe a new method of treatment of multicentric sinonasal inverted papilloma by laser endoscopic coagulation. MATERIAL AND METHODS: We report a case of multicentric sinonasal inverted papilloma involving the nasopharynx in a 62-year-old man. The treatment was a laser diod cauterisation. RESULTS: The evolution was favourable without complications or recurrence after a 16 months follow-up period. CONCLUSION: Laser endoscopic coagulation seems to be an effective treatment for multicentric sinonasal inverted papilloma especially for lesions with a difficult surgical access.
