Nasal NK/T-cell lymphoma in the paediatric population. Two case reports.

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.

[Laryngeal cryptococcosis revealing AIDS: a case report]. / Cryptococcose laryngée révélatrice d'un SIDA: à propos d'une observation.

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.

[Extra-nodal T lymphomas of the nasal cavities and sinuses]. / Les lymphomes T des fosses nasales et des sinus.

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.

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

Les tumeurs parotidienne de l'enfant a propos de 13 cas

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

L'otite externe necrosante place de l'oxygenotherapie hyperbare

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

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

Mastiodite masquée : à propos de deux observations

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

Les tumeurs oncocytaires de la thyroide : a propos de 25 cas

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

[Regional failure of hypopharyngeal squamous cell carcinoma]. / Echecs ganglionnaires du carcinome épidermoïde de l'hypopharynx.

PURPOSE: Lymph nodes and distant metastases contribute to the poor prognosis of hypopharyngeal squamous cell carcinoma. The purpose of this study is to estimate the frequency, mode and prognosis factors related to regional and distant metastasis. PATIENTS AND METHOD: The authors' report is based on a retrospective study concerning 271 hypopharyngeal squamous cell carcinoma, compiled in the service of Surgery of Head and Neck Cancers of the Salah-Azaïz Institute (1977-2002). Frequency and histoclinical characters of cervical and distant metastases have been assessed, as well as their prognosis factors among 155 patients treated in a curative purpose. RESULTS: 39.1% of the tumours were classified N0, 24.4% N1, 10.7% N2 and 25.8% N3 (UICC 2002). The cervical nodal invasion was significantly more frequent for the classified tumors T3T4 than for the T1T2 (for pyriform sinus, postcricoid esophagus, posterior wall, and total hypopharynx, respectively : P =0.001, P =0.007, P =0.047 and P =0.0005). A cervical lymphatic evidement was preferred in thirty two patients. Among N0, 46.9% were N+; The frequencies of the capsular effraction were not significantly different for the N0N1 from for the N2N3 (P =0.11). The two and five years survival rates were respectively 32.5 and 20.5% for N0, and 10.9% and zero for N3. The survival differences after two and five years between the N0N1 and the N2N3 were significant (P =0.04). A regional failure was noticed for 18.5% of the patients. The tumoral site did not influence significantly the rate of nodal failure (P =0.98), neither the clinical status N (P =0.34). Capsular effraction was a significant factor for the regional failure (P =0.007). Distant metastasis significantly occurred more frequently among the patients initially classified N2N3 than those classified N0N1 (P =0.03), and in case of capsular effraction (P =0.0009). CONCLUSION: Hypopharyngeal squamous cell carcinoma has a high rate of lymph nodes metastasis, correlated to the local extension, and a high rate of occult nodal metastasis. Lymph node clinical status does not seem to have influenced the patients survival; however, capsular effraction constitutes a major prognosis factor of regional failure and distant metastasis. Distant metastases are frequent, particularly in case of wide local and regional tumoral extension.

[Hypopharyngeal squamous cell carcinoma: retrospective study of 149 patients]. / Carcinome épidermoïde de l'hypopharynx: étude rétrospective de 149 traitements à visée curative.

PURPOSE: Hypopharyngeal squamous cell carcinoma is associated to one of the most unfavorable prognosis among the cancers of the head and neck. The purpose of this study is to analyze its therapeutic modalities in the Salah-Azaïz Institute (Tunis) and to compare their results. PATIENTS AND METHOD: This retrospective study concerns 271 hypopharyngeal squamous cell carcinomas, compiled in the Carcinologic Surgery Department of Head and Neck of the Salah-Azaïz Institute over a period of 25 years (from 1977 to 2002). The average age of the patients was of 56 years; sex-ratio was on average of 1.2 (man/woman). The indication of a curative treatment was initially retained for 149 (55%) patients, who were the only ones retained for the analysis of results. RESULTS: We retained the indication of a protocol including surgery and postoperating radiotherapy for 26.2% of the patients. Postoperation mortality rate was 5.1%; the operating rate of morbidity was 46.2%. For 13.5% of the patients, postoperating radiotherapy was permanently interrupted because of a gradual deterioration of the patients' health in the course of treatment. We retained the indication of exclusive radiotherapy for 59.7% of the patients. The average age was of 56 years and the sex-ratio of 1.2. The external radiotherapy was conventional. Radiotherapy had to be permanently interrupted in progress in 32.6% of cases on account of an deterioration of the patients' health; the rate of morbidity of the radiotherapy was 33.3%. We indicated a protocol of conservation of organ with induction chemotherapy for 21 patients (14.1%). The average age was of 53 years (28-65 years) and sex-ratio (man/woman) of 0.5. The global survival was 25.5% at one year, 18.1% at two years, 11.4% at three years and 7.4% at five years. All the patients selected for chemotherapy died in the course of treatment. The rates of survival in two and five years according to protocols surgery-radiotherapy and exclusive radiotherapy were respectively: 21.5 and 12%, and 18.3 and 10%. The difference between the rates of survival of this two protocols is not significant (P =0.08). CONCLUSION: Although the induction chemotherapy entails a particularly high death rate in our series, the association surgery-radiotherapy and the exclusive radiotherapy seem to be similarly efficient for the treatment of the hypopharyngeal carcinoma.
