Intussusceptions in adults is rare. Gastrointestinal lipomas are rare benign tumors and intussusceptions due to a gastrointestinal lipoma constitutes an infrequent clinical entity. Lipoma may develop as a benign tumor in all organs and rarely in large or small intestine. The present report describes a case of jejunojejunal intussusceptions in an adult with a history of colicky upper abdominal pain. Ileo-ileal invagination was diagnosed by computed tomography scan. Exploratory laparotomy revealed jejunojejunal intussusceptions secondary to a lipoma which was successfully treated with segmental intestinal resection. A review of the literature is also performed regarding this rare association revealing the diagnostic and therapeutic debates that exist.Abstract (french)L’invagination chez les adultes est rare. Les lipomes gastro-intestinaux sont de rares tumeurs bénignes et l’invagination intestinale due à un lipome gastro-intestinal constitue une entité clinique trés rare. Le lipome peut se développer comme une tumeur bénigne dans tous les organes et rarement dans l’intestin grêle ou le colon. Le présent rapport décrit un cas d’invagination jéjunojéjunale chez un adulte avec une histoire de douleurs abdominales. Iléo-iléale invagination a été diagnostiquée par tomodensitométrie. Une laparotomie exploratrice a révélé l’existence d’une invagination jéjunojéjunale secondaire à un lipome qui a été traitée avec succès par une résection intestinale segmentaire. Une revue de la littérature est également effectuée au sujet de cette association rare révélant les débats diagnostiques et thérapeutiques qui existent.
Perivascular epithelioid cell tumors (PEComas) encompass a group of rare mesenchymal neoplasms, which typically have a perivascular location with dual melanocytic and muscular differentiation. They are found in a variety of localizations, though lesions in the liver are exceedingly rare. Because of their rarity, the clinical, radiological and histological features of these tumors have yet to be established. This is why, it seems appropriate to report the observation of this rare hepatic tumor with a literary review including others published cases, assessing through it, clinicopathologic and radiologic features of all reported cases as well as their follow-up whenever possible.Virtual SlidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1967094999126169
IntroductionCecal volvulus is an uncommon cause of intestinal obstruction due to an axial twist of the caecum, ascending colon and terminal ileum around the mesenteric pedicle. It is responsible for 1%-1.5 of all intestinal obstructions in adult. The clinical signs may be highly variables and can be responsible of delays in diagnostic and treatment. The delay in diagnosis leads to intestinal necrosis or perforation. The mortality ranges from 10 to 40% depending on the presence of a viable or gangrenous intestine.Presentation of caseA 64 year old woman admitted the emergency department for acute bowel obstruction. Clinical examination found typically acute bowel obstruction signs. Plain radiography showed dilated gas-filled segment of the colon in the left side of abdomen and volvulus of cecum was suspected. Enhanced abdominal CT scan confirmed the diagnosis. Emergency exploratory laparotomy was performed and confirmed the cecal volvulus. A manual untwisting of volvulus and a Caecopexy were performed. The patient subsequently recovered uneventfully and was discharged on postoperative day 3.DiscussionThe management of cecal volvulus requires prompt (emergency) diagnosis and prompt surgical intervention. Any delay in diagnosis may lead to intestinal necrosis or perforation and worsening the prognosis in patients who are generally elderly. Several authors reported a high mortality rate of cecal volvulus due to delay to diagnosis and surgical intervention.ConclusionThe low incidence of this condition needs a high index of suspicion and emergency surgical management. Despite significant progress in medical imaging, the preoperative diagnosis of cecal volvulus is very difficult. As a result, the treatment is often delayed.
Le but de ce travail était d'analyser les caractéristiques cliniques, histologiques, thérapeutiques et pronostiques du cancer du sein chez l'homme. Il s'agissait d'une étude rétrospective portant sur six patients colligés au service de gynécologie obstétrique II, CHU Hassan II durant la période 2009-2012. L’âge moyen de nos patients est de 65.3 ans. Il s'agit dans 83.3% des cas, d'une tumeur rétroaréolaire dont la taille moyenne est de 44.16 mm. Nous avons retrouvé 4 (66.7%) T4, 1 (16.7%) T3 et dans un cas, une tumeur inclassable. Le type histologique le plus représenté est le carcinome canalaire infiltrant (66.7%). Le taux d'envahissement ganglionnaire axillaire est de 66.7%. L'hormonodépendance de ces tumeurs est prouvée dans 100% des cas. La survie à cinq ans est en cours d’évaluation. L'envahissement ganglionnaire, l'invasion du derme, le stade clinique TNM sont des facteurs qui influencent significativement la survenue de métastases. Aucun de ces facteurs de risque n'est apparu significatif en termes de survie globale. Le cancer du sein chez l'homme est une maladie rare (environ 1% des cancers du sein) au pronostic sombre. Le diagnostic est le plus souvent tardif et les lésions sont traitées à des stades avancés.
