[Mesenteric abscess due to Chryseobacterium meningosepticum revealing mesenteric Castleman´s disease in an immunocompetent young adult]. / Abcès mésentérique du au Chryseobacterium meningosepticum révélant la maladie de Castleman à localisation mésentérique chez un jeune adulte immunocompetent.

Mesenteric abscess caused by chryseobacterium meningosepticum is an extremely rare clinical entity, most often found in immunodeficient patients. Castleman disease can manifest as a mesenteric abscess. We here report the case of a 23-year-old patient admitted with generalized acute peritonitis evolving over the last 2 weeks. Abdominal ultrasound showed hypoechoic mass in the intestinal loops, without any further details. During laparotomy, pus was found in the large cavity, a mesenteric abscess was detected in the mesentery of the jejunum 35 cm from the angle of Treitz, without loop perforation and mesenteric adenopathy was found in corresponence with the abscess. Pyoculture isolated chryseobacterium meningosepticum. Histological analysis of mesenteric adenopathy biopsies showed structural anomalies, suggesting hyaline vascular type of Castleman disease. Treatment was based on incision and drainage of the abscess, with pyogenic membrane removal and abdominal cavity lavage with physiological saline solution. Chryseobacterium meningosepticum was only susceptible to Ciprofloxacin. The postoperative course was simple and the patient was discharged on postoperative day 10 after surgery. Clinical and paraclinical follow-up at 12 months did not show any other lymphadenopathy or recurrence. The purpose of this study is to show an extremely rare case of mesenteric abscess due to chryseobacterium meningosepticum associated with isolated mesenteric Castleman disease in an immunocompetent patient and management approaches.

[Angiosarcoma of the shoulder revealed by previous trauma: about a case and literature review]. / Angiosarcome de l´épaule révélé par un ancien traumatisme: à propos d´un cas et revue de la littérature.

Angiosarcoma is a rare tumor which can affect multiple sites. However, it most commonly arises from the skin. Then symptoms have been associated with clinical polymorphism. This tumor has a poor prognosis due to its high tendency to local recurrence and distant metastases. We here report the case of a 72-year old man in whom an angiosarcoma of the shoulder arose from a trauma which occurred one year before it was accidentally detected. The patient presented with persistent pain in a swelling area at the posterior portion of the shoulder involved in the trauma. Clinical examination showed previous and partially calcified hematoma. Diagnosis was based on puncture biopsy of the mass collecting 5 cc of blackish blood and on ultrasound. Shoulder x-ray was normal. An assessment of the swelling was performed. This helped to highlight and resect some reddish, significantly bleeding friable tissue hardly managed for two days and complicated by poorly tolerated anemia corrected with two blood transfusions. Anatomopathological examination of the resected tissues showed moderately differentiated angiosarcoma unfortunately without healthy margins. Staging evaluation was performed in order to detect metastases. No local recurrence was reported over a period of three months and the patient was referred to a specialized center in Lusaka for complementary radiotherapy. The purpose of this work is to report a rare case of angiosarcoma accidentally detected in a patient with a history of trauma to the left shoulder and to highlight the therapeutic features, while conducting a literature review.

[Acute prostatitis associated with noncancerous prostate at the Lubumbashi University Clinics: epidemioclinical and therapeutic features]. / Prostatites aiguës sur prostate non tumorale aux cliniques universitaires de Lubumbashi: aspects épidémio-clinique et thérapeutique.

INTRODUCTION: acute prostatitis is a common urological condition. The purpose of this study was to analyze the epidemioclinical features and therapy of acute prostatitis associated with noncancerous prostate at the Lubumbashi University Clinics. METHODS: we conducted a descriptive cross-sectional and retrospective study of a series of 25 patients with documented acute prostatitis and treated at the Lubumbashi University Clinics over a period of four years, from 2015 to 2018. All patients with prostate cancer were excluded from our study. Data were collected via a survey form based on different study parameters divided into 3 categories, namely epidemiological data including age, study period, residence, clinical data with subjective signs, objective signs, general status, findings on rectal examination as well as paramedical data divided into laboratory and imaging tests. RESULTS: acute prostatitis associated with noncancerous prostate accounted for 1.27% of all surgical diseases and 7.66% in urology. The most affected age group was 19-37 years (64% of cases), mean age was 33.16±2.4 years. Seventeen patients (68%) were followed up in outpatient clinics and 8 (32%) in hospital. Clinically, fever above 38.5°C was found in 15 patients (60%), dysuria in 11 patients (44%), acute urinary retention in 3 patients (12%), burning during urination in 8 patients (32%), pain syndrome in 21 patients (84%), tender prostate on rectal examination in 18 patients (72%). Ultrasound was the only examination performed in 16 patients (64%). Biologically, assessment of inflammation was performed almost systematically in all patients (100%) including complete blood count (CBC), sedimentation rate (SR), C reactive protein (CRP) levels; blood culture was performed in 4 patients (16%), three of whom had positive blood culture. All patients underwent cytobacteriological examination of the urine or prostatic secretions collected by prostate massage. Urine culture was sterile in 6 patients (24%) and positive in 19 patients (76%). Escherichia coli was the most common germ in 16 out of a total of 19 patients (84.21%). All patients received rectal anti-inflammatory drugs. Fluoroquinolones were the most used antibiotics in 18 patients (64%), twelve of whom received antibiotics as monotherapy. Six out of 25 (24%) cases were associated with orchiepididymitis. The lenght of treatment ranged from 2 to 4 weeks, with either sterilization in secretions or urine or disappearance of leukocyturia as the criteria for treatment discontinuation. Thus, out of 19 patients with positive culture on admission, 14 underwent a second culture (73.68%) at 2 weeks of treatment, three of whom (12%) still had positive test and had to undergo a third culture 4 weeks after they had started treatment. Patient's course was good in 22 cases (88%) with complete clinical and biological remission; three patients (12%) persisted in symptoms which became chronic; no patients had prostatic abscess. CONCLUSION: acute prostatitis associated with noncancerous prostate is a really worrying urological, nosologic condition whose management must be rigorous, especially in people at risk, namely those with intense sexual behaviour. Endorectal ultrasound and prostate massage should be integrated into patient care at the Lubumbashi University Clinics.
