This retrospective study, the first of its kind in Mauritania, was carried out at the military hospital of Nouakchott. We sought to approximate the epidemio-logical, anatomopathological profile of Ear, Nose and Throat (ENT) and cervico-facial (CF) cancers in Mauritania. Over a period of two years, from January 1, 2019 to December 31, 2020, we noted 36 histologically confirmed cases, they represented 15.47% of all patients consulted in ENT and CF cancers affected the age group between 25 and 70 years, the age group most affected was that of 50 and 59 years, with 33.33% of cases. More affected in the proportion of 2 men to women, which can be explained by the risk factors mainly found in men, including smoking. First rank was cancers of the upper aero-digestive tract, the pharyngolarynx in head. Histologically, ENT and CF cancers were dominated by squamous cell carcinomas 78%, well ahead of papillary carcinomas 8% and vesicular thyroid carcinomas 5%, UCNTs, adenosquamous carcinomas and lymphomas each represented 3%.

Histoplasmosis is an opportunistic granulomatous fungal infection. Peritoneal histoplasmosis (PH) is a rare form. The first case of PH was described in 1970 but this is the first case reported in Mauritania. We report the case of a 60-year-old male patient with a history of pulmonary tuberculosis, treated and declared cured, and partial epileptic seizures treated with Carbamazepine. Contrast computed tomography of the abdomen showed a large mass with a large intraperitoneal fluid component with a finely calcified wall in places, for which laparoscopy and biopsy were performed, identifying Histoplasma capsulatum infection. The subject received treatment with amphotericin B deoxycholate with good evolution, and outpatient management with itraconazole. PH is a rare entity that requires high clinical suspicion, especially in immunocompetent patients. The patient was informed that non-identifying information from the case would be submitted for publication, and he provided consent.

The Askin tumour is a highly malignant rare tumour with small cells, pertaining to the group of the primitive neuroectodermal tumours. It develops with the costs of the soft parts of the thoracic wall and it’s characterized by extra and endothoracic fast extension. We report seven cases colliged in our service by specifying the role of the imagery in the diagnosis but especially the assessment of extension of these tumours.

The hydatid disease establishes a real problem of public health in our country. The hydatid cyst is preferentially located at the level of the liver and the lungs. Its mediastinal location is extremely rare, representing 0à 4% of all the hydatic locations. The imaging plays an important role in the diagnosis of this affection and in the balance sheet of extension in search of another location. The hydatid cyst also raises a diagnostic problem with the cystic hurts of the mediastinum. We report a case of mediastinal hydatid cyst colliged in the service of general surgery at the 5th military hospital.

Urethral stones are a very rare form of urolithiasis, they most often originate from the upper urinary tract or bladder, and are rarely formed primarily in the urethra, it is formed on a urethral anatomical pathology in the majority of cases. The clinical symptomatology is very variable ranging from simple dysuria with penile pain to acute retention of urine. Smaller stones can be expelled spontaneously without intervention, but larger stones or complicated stones or those developed on an underlying urethral anatomical pathology require surgical treatment. The minimally invasive treatment should be the preferred route for the surgical treatment of this disease when feasible. We report the case of a young man with no particular pathological history who presented to the emergency department for acute retention of urine secondary to a primary fossa navicularis calculus, through this case, we discuss the different clinical aspects, etiology, pathogenesis, diagnosis and therapy of urethral stone in men.

Introduction: Kidney cancer represents 2% to 3% of malignant tumors, with an incidence of 5.8/100,000 in Western countries, a very specific subgroup of renal tumors that are cystic tumors. In fact, almost 50% of the population over 50 has a renal cyst. Materials and Methods: The objective of this study is to establish a correlation between the preoperative Bosniak score and the postoperative anatomopathological analysis in order to answer this question, the use of contrast ultrasound or MRI should be systematically performed before an atypical renal cyst? This is a retrospective study of 50 patients treated for renal cysts between January 2010 and March 2016. All patients have an abdominopelvic ultrasound and an abdominal scanner. Cysts have been classified according to the Bosniak classification. We treated our patients based on the radiological examination urocsanner and we classified our patients according to the classification of Bosniak, and uro MRI was performed in cases of atypical cysts or diagnostic doubt before considering a therapeutic attituderding to the classification of Bosniak. Results: In our work, the Uro MRI was sharper for atypical cysts (type IIF and Type III cyst) with sensitivity greater than that of the scanner but with a specificity similar to that of the scanner. And therefore be a key examination in the atypical kidney cysts. Conclusions: URO MRI is currently in 2020 a key examination of atypical bonsiak IIf and III cysts before management of the therapeutic load.

The introduction of w-operation in the class of flat modules has been successful. Let R be a ring. An R-module M is called a w-fiat module if Tor1r（M, N） is GV-torsion for all R-modules N. In this paper, we introduce the w-operation in Gorenstein homological algebra. An R-module M is called Ding w-flat if there exists an exact sequence of projective R-modules ... → P1 → P0 → p0 → p1 → ... such that M Im（P0 → p0） and such that the functor HomR （-,F） leaves the sequence exact whenever F is w-flat. Several well- known classes of rings are characterized in terms of Ding w-flat modules. Some examples are given to show that Ding w-flat modules lie strictly between projective modules and Gorenstein projective modules. The Ding w-flat dimension （of modules and rings） and the existence of Ding w-flat precovers are also studied.
