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.

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.
