Introduction:The tumours of skin adnexal are rare and very often benign. Because of their large diversity they caused some diagnose and classification problems. They are tumours of ten mixed up with other skin tumours. The objective of this study was to study the histopathological and epidemiological profile of the benign skin adnexal tumours in Ouagadougou and to classify them according to the differenciation type in order to well know them and improve their treatment. Methodology: We conducted a retrospective study on the period of sixteen years going from 1 st January 1998 to 31 December 2013. This study interested all cases of benign skin adnexal tumours histologically confirmed (diagnosed) in the three pathology laboratories of the Ouagadougou town. Results: We collected sixty cases of skin adnexal tumours on the total of 763 cases of skin tumours representing 7.8%. The benign tumours represented 86 % of the adnexal tumour cases. These tumours were occurred in the relatively young age and were preferentially located on the head (cephalic) extremity. On the histological plan, the hair follicle tumours were more frequent (42.5%) followed by sweat gland tumours (30.5%) and sebaceous gland tumours (27%). Conclusion: The annex tumours are majoritary benign occurring often on the head extremity and dominated by the hair follicle tumours.

Contexte : Les études sur les méningiomes rapportent des résultats variables à travers le monde. Différentes études trouvent les méningiomes, les gliomes ou les méta-stases comme la plus fréquente des tumeurs du système nerveux central (SNC). Notre travail a pour but d'étudier la place des méningiomes dans la morbidité liée aux tumeurs du SNC dans notre contexte. Matériel et méthode : Quatre-vingt-six cas de tumeurs du SNC, issus de l'unité de neurochirurgie du CHU-YO et diagnostiqués à l'histologie ont été rétrospectivement collectés de 2005 à 2011 à travers tous les laboratoires d'anatomie pathologique de Ouagadougou. Au cours de cette période, 198 cas de tumeurs du SNC diagnostiqués au scanner ont été répertoriés dans cette unité, seule prenant en charge les cas au Burkina. Résultats : Trente et un cas de méningiome ont été histologiquement diagnostiqués, et constituaient les tumeurs les plus fréquentes (36,04 %), suivis des gliomes (34,49 %), des métastases (7,33 %), puis des tumeurs hypophysaires (5,81 %). L'ensemble des 86 cas de tumeurs du SNC étaient constitués de 55,61 % d'hommes et 44,39 % de femmes ; l'âge moyen était de 37,05 ans. Les 31 cas de méningiome ont concerné 19 femmes (61,3 %) et 12 hommes (38,7 %), soit un sex-ratio hommes/femmes de 0,63. L'âge variait de 13 à 86 ans, avec une moyenne de 45,32 ans. Le sous-type histologique méningothélial était prédominant avec 35,48 % des cas. Les méningiomes de grade I (bénins) représentaient 90,31 %, et les méningiomes atypiques (grade II) et malins (grade III) 9,69 % des cas. Conclusion : Les méningiomes sont les tumeurs les plus fré-quentes du SNC dans notre contexte, avec prédominance du sous-type méningothélial de grade I.

Different reports state meningiomas, gliomas, or metastatic tumors as the most common tumors among central nervous system neoplasms. The aim of our study was to determine the relative frequency of meningiomas among central nervous system neoplasms in our environment. Method: Consecutive patients (86) seen at Neurosurgery Office of Yalgado Ouédraogo Teaching Hospital of Ouagadougou, with histologically proven central nervous system tumor over a 7 years period (2005)(2006)(2007)(2008)(2009)(2010)(2011), were retrospectively analyzed. Results: The commonest histological types were meningiomas, gliomas, metastasis, and pituitary tumors. Thirty-one patients (36.04%) had histologically confirmed meningioma during the study period, 25 (29.07%) had glioma, 6 (7.33%) had metastasis, and 5 (5.81%) had pituitary adenoma. The mean age of the 86 patients was 37.05 years, with 55.61% of male. The mean age of the meningiomas cases was 45.32, with 61.3% of female. 90.31% had grade I meningioma.

Introduction: Pneumatosis cystoides intestinalis is a rare condition characterized by the presence of gas cysts in the intestinal wall. It can affect different segments of the digestive tract. Male patients over 50 years old seem to be more affected. Classically, one opposes the primary or idiopathic forms and the secondary forms. Case Report: We report the case of a 62-year-old female patient with a history of treated peptic ulcers, who presented with episodes of intermittent atypical abdominal pain that worsened abruptly. The physical examination revealed a surgical abdomen with tenderness to palpation. The patient underwent a jejunal resection. The pathological examination showed macroscopically an intestinal fragment with confluent subserosal and intestinal intraparietal bullae. On opening, the portion containing the bullae was thickened, infarcted, congestive, hemorrhagic, and brittle with narrowing of the intestinal lumen. The bullae are tense and leave serosities. On histological examination, the intestinal wall was very congestive with hemorrhagic patches of suffusion. There were optically empty cystic formations that does not communicate with the digestive lumen. The adjacent mucosa is the site of a moderate subacute inflammatory reaction. Conclusion: Pneumatosis cystoides intestinalis is a rare and usually benign pathology. The symptoms, when they exist, are not specific. Its physiopathology is still very much debated. The prognosis is generally good. The knowledge of this pathology is necessary to avoid invasive explorations and heavy treatment without interest for the patient.
