Melanocytics Tumors on Black Skin: About 2 Cases of Anal Location

In black skin, the epidemiology of anal melanocytic tumors is little studied and is generally based on reported cases. Anal localization is characterized by its rarity, and its non-consensual management. In this study we describe and discuss the anatomopathological aspects which led to the fortuitous discovery of a case of nevus and a case of melanoma of anal location. The cases involved samples taken from a 30-year-old female and a 75-year-old male. Both examinations concerned surgical pieces received fixed. Histological and immunohistochemical examination was performed for both observations. In the case of the nevus, the histological appearance was misleading and difficult, initially evoking a melanoma. The diagnosis of the melanoma case was easier and confirmed by a positive HMB45 staining. In proctology, melanocytic tumors are rare with a variable and nonspecific clinical presentation. Melanoma on black skin occurs in locations that are not photo-exposed mucous membranes with a poor prognosis.</jats:p

Granulomatory Mastitis: A histological benign lesion with a malignant Radioclinical profile: About 3 Cases

Granulomatous mastitis is characterized by an inflammatory lesion of the breast lobules without caseous necrosis and without microorganisms. It has a probable immunological origin by analogy to thyroiditis or granulomatous orchitis. Frequently the lesion presents itself in a clinical and mammographic form raising suspicion of a malignancy. We report 3 observations of granulomatous mastitis confirmed histologically whose clinical and radiological presentations clearly pointed towards malignancy. This lesion constituted in our three cases an example of radio-clinical and histological discrepancy.</jats:p

A 14 years old woman with a giant mucinous adenocarcinoma of the ovary

The diagnosis of ovarian tumor in pediatrics is often difficult and delayed due to unspecific call signs and polymorphic imaging presentations. These tumors are rare, estimated in children at around 2.6 / 100,000 girls per year, functional lesions being excluded. Ten to 20% of them are malignant [1-2] and represent 3% of cancers in girls under the age of 15 [3]. The World Health Organization classifies these tumors into three main groups based on whether they are derived from the surface epithelium, germline cells or ovarian stroma or sex cords. Primary or secondary locations are possible in leukemias and lymphomas [4-5]. Giant ovarian cystadenocarcinomas are rarely described. The huge ovarian masses are mostly benign, but the malignancy should be ruled out by pathology exams. Giant cysts require resection by laparotomy because of compression symptoms or the risk of malignancy, but also to prevent perforation and spillage of cystic fluid into the peritoneal cavity [6]. Here we report an observation made in a 14-year-old girl who was diagnosed with a large ovarian tumor and who was found to be a malignant tumor on pathology with papillary-type mucinous cystadenocarcinoma.</jats:p

3D Digital Imagery a Solution for the Teaching of Osteology: Example of the Thoracic cage

Osteology is a fundamental discipline, its classical teaching becomes difficult because of plethora of students and shortage of bony parts. It’s in this context that we have made, from 3D volume imaging, a modeling of the rib cage as a test using a software for post-treatment of CT images in order to propose a pedagogical tool for studying thorax’s skeletal and adding descriptions with the help of classical works. This was a prospective study involving 27 patients aged between 35 and 45 years. The scanners used were HITACHI ECLOS 16 cuts. Once the CT scan was selected, the DICOM data was transmitted to the post-processing console. The images were processed on the console "Aquarius Intuition Edition Version 4. 4. 7. 855113", for one patient we used Veiwer Osirix 10.6.8 Mac. All bones have been dynamically described thanks to the volume rendering. We thus obtained volumetric reconstructions of three-dimensional CT images of the different bone structures superimposed on those taught in classical anatomy practical work. We obtained a scenario of practical work in the form of a slide show that the teacher can use for works with or without model and even remotely. The virtual reality obtained with the 3D reconstructions of CT scans of the rib cage is a tool for self-learning of osteology for students but also a way for teachers to do practical work without having to use models, and even at a distance. KEY WORDS: 3D imaging, Teaching, Tomodensitometry, Osteology.</jats:p

Management of placenta percreta. A case report

The placenta accreta designates an abnormality of the placental insertion characterized, on the anatomopathological level, by an absence of deciduous deciduous between the placenta and the myometrium. This insertion anomaly may interest all or only part of the placenta. We distinguish within this terminology the terms of - placenta accreta when the placenta is simply attached to the Myometrium. - placenta increta when the placenta invades the myometrium. - placenta percreta when the placenta enters the serosa uterine, or even the neighboring organs (bladder, peritoneum, etc.) [1]. Placentas accretas are a high-risk situation for severe postpartum hemorrhage and its inherent complications such as disseminated intravascular coagulation, hemostasis hysterectomy, surgical wounds to the ureters, bladder, multiple organ failure, or even maternal death, particularly in the case of placenta percreta [2,3]. Risk factors for placenta percreta include a history of cesarean, uterine curettage or manual removal of placenta, presence of placenta previa, endometriosis, high parity and advanced maternal age [4]. We report the case of a 30-year-old woman, IIGIIP, who had a previous cesarean section during her first pregnancy and who had a placenta percreta and who underwent hysterectomy without cystectomy and without ligation of the hypogastric arteries.</jats:p

An Isolated Dextrogastria Simulating Diaphragmatic Rupture in a Post-Traumatic Context

We report a case of isolated dextrogastria discovered in imaging a 34-years-old woman who was in the emergency department for vomiting and fluctuating right chest pain following a road accident. It was a collusion between 2 motorcycles, the patient being a rear passenger, performing a whiplash mechanism with a brief initial loss of consciousness. The day after the accident, she complained of left cervical swelling, painful with dysphagia to solids. Physical examination revealed bilateral palpebral oedema. There was a decrease in right vesicular murmurs with symmetrical tympanism towards the base of the lung. The rest of the examination was normal. The chest x-ray showed digestive loops above the liver that appeared to be located in the right intra-thoracic, suggesting in this context a diaphragmatic rupture. The OGDT and the thoraco-abdominal CT made possible to correct the diagnosis of type II dextrogastria by showing the stomach and part of the colon located on the right, above the liver, under the diaphragmatic dome which is disembowelled, pushing back the lung homolateral up. There was also a deviation of the ipsilateral thoracic esophagus in continuity with the stomach. The liver, in the right quasi-lateral position, is forced downward, extending to the lower edge of the ipsilateral flank. The other viscera kept their usual topographies.
