A juxtaglomerular cell tumor revealed by a hemorrhagic stroke. A case report.

With about 110 cases reported in literature, juxtaglomerular cell tumors are rare. We report a 25 years old patient who was admitted in neurology for a hemorrhagic stroke secondary to a cerebral aneurysm rupture due to high blood pressure. Etiological investigations showed a solid mass of the left kidney. A radical nephrectomy was realized and pathological examination and immunohistochemical profile concluded to juxtaglomerular cell tumor. The originality of this observation is based on the mode of presentation of a rare renal tumor by a malignant high blood pressure.

Prostate adenocarcinoma metastasis to the testis: A new case report.

Prostate cancer (PCa) in the second most common cancer in men worldwide. It commonly metastasizes to the bone, lymph nodes, liver and lungs. Synchronous or metachronous testicular metastasis is a rare finding, generally diagnosed incidentally after bilateral orchidectomy for hormonal management in patients with advanced PCa, or at autopsy. We report a case of a 55-year-old male, presenting a PCa and who developed a single testicular metastasis treated by radical orchidectomy, while he was under hormonotherapy.

[Evaluation of management of patients under clean intermittent catheterization by general practitioners]. / Évaluation de la prise en charge des patients sous sondage intermittent propre par les médecins généralistes.

INTRODUCTION: Clean Intermittent Catheterization (CIC) is the method of choice for bladder emptying in patients having bladder emptying disorders, acquired or pharmacologically induced, whether it is neurologically related or not. The aim of this study is to assess the theoretical and practical knowledge of general practitioners (GP) on CIC. MATERIALS: Observational prospective study (anonymous online questionnaire) was conducted with 224 GP between March and April 2020. Each physician had to complete a questionnaire about the definition of CIC, its indications and usage, the indications of urine culture, antibiotic therapy, and the complications of this method of drainage. RESULTS: Only 18.3% of GP that took part in the study gave an exact definition of CIC. As to the importance of it, 67.9% responded that it protects the upper urinary tract and 37.1% that it prevents urinary tract infections (UTI). Fifty-two per cent of physicians were unaware of the regular frequency at which it should carry out a day. Fifty eight percent prescribed sterile gloves and 57.1% an antiseptic. UTI was considered as the main complication of CIC by 87.1% of physicians and 35.7% requested a systematic urine culture for patients under CIC. For patients with an asymptomatic bacteriuria, 65.6% of GP prescribed antibiotic therapy. CONCLUSION: GP need to improve their knowledge of SIP, its framework, indications, modalities, and the way to deal with colonization or urinary tract infection. This will improve the management of impacted patients.

Vesico-vaginal fistula in Tunisia: Epidemiology and risk factors of treatment failure.

INTRODUCTION: Vesico-vaginal fistula (VVF) is a global healthcare problem that has a high prevalence in developing countries. The aim of this work is to study the epidemiological, clinical and therapeutic characteristics of VVF post-obstetric and gynecologic procedures in order to identify the predictive factors of surgical treatment failure. METHODS: Data were collected from 132 VVF patients in our institution between 1985 and 2017. VVF was classified according to Zmerli's classification. Patients underwent surgical treatment and were evaluated after a follow-up period of 6 months. Successful treatment was defined as the absence of urine leakage whereas recurrence was defined as the presence of urine leakage immediately after the surgery or after a period of dryness with a confirmed VVF. Risk factors of surgical treatment failure were identified. RESULTS: The average age of patients was 44 years. The patients were multiparous in 62% of cases. VVF was consecutive to hysterectomy in 62.1% of cases, and after childbirth in 34%. VVF was retro-trigonal in 99 cases (75%) and trigonal in 33 cases (25%). The average size of the fistula was 1cm (0.3-2cm). VVF repair was performed by vaginal approach in 68% of cases and abdominal approach in 32% of cases. Treatment failure was noted in 36 patients (27%). Predictive factors of treatment failure were: vaginal fibrosis (P<0.001); trigonal location of the fistula (P<0.001); large diameter of the VVF>1cm (P<0.001); and complex and complicated fistulas (P=0.02). CONCLUSION: Although Tunisia is a developing country, the main cause of VVF was not obstetrical. Treatment failure, noted in almost one third of cases, was, in our series, correlated with the quality of the vaginal tissue, the size and the location of the fistula, and its complexity. LEVEL OF PROOF: 4.

Metachronous isolated locally advanced pancreatic metastasis from chromophobe renal cell carcinoma.

INTRODUCTION: Metastasis to the pancreas is relatively uncommon occurrence. Isolated pancreatic metastasis from renal cell carcinoma (RCC) is relatively rare and it's usually seen in clear cell renal cell carcinoma (CCRCC), but its occurrence from chromophobe renal cell carcinoma (chRCC) is extremely rare, due to its relatively low-grade metastatic potential. PRESENTATION OF CASE: The authors report an unusual case of metachronous isolated pancreatic metastasis, in a 65-year-old female patient two years after left nephrectomy for chRCC, diagnosed during routine surveillance imaging and confirmed after a CT-guided pancreatic biopsy. DISCUSSION: The pancreas is an elective site for metastases from RCC, and this particularity has been reported by several studies, but only described for CCRCC. In the English literature there is only one case of pancreatic metastasis from chRCC diagnosed in an autopsy study. Surgical resection of metastasis remains the most effective treatment, particularly for pancreatic metastases from chRCC, since radiotherapy, chemotherapy, hormonal therapy, and targeted therapy have generally proved ineffective for metastatic chRCC. In case of an unresectable disease, surgical or endoscopic palliation in association with palliative chemotherapy can improve the quality of life but not survival. CONCLUSION: This case highlights the unique behavior of chRCC with an unusual site of metastasis, and the necessity of long-term follow-up after primary tumor removal, even if it is known for a low-grade metastatic potential and a relatively good prognosis.

Malignant rhabdoid tumor in a solitary kidney arising in an adult patient with chronic obstructive renal calculi.

INTRODUCTION: Malignant rhabdoid tumor (MRT) is one of the most aggressive and lethal malignancies in pediatric oncology, MRT of the kidney is an uncommon renal tumor in children and it's extremely rare in adult patients. With only seven previously reported adult cases in the English-literature, to our knowledge this is the first case that is associated with renal calculi. PRESENTATION OF CASE: We present the case of a 65-year-old man with an MRT arising in a solitary kidney with multiple enlarged lymph nodes that compressing the inferior vena cava. DISCUSSION: Malignant rhabdoid tumor of the kidney was originally described as a "rhabdomyosarcomatoid" variant of Wilm's tumor due to the resemblance of cells to rhabdomyoblasts, now this type of tumor is recognized as distant and unique malignant renal tumor. It affects usually children before the age of 2 years. Tumor tissue sampling is required to make the diagnosis of MRTK, based on either nephrectomy, core biopsy, or autopsy specimens. There is no established standard of care due to the paucity of cases. Surgery is considered to be the first choice of treatment if possible. CONCLUSION: This case report reinforces the importance of recognizing this entity in the adult population, and discuss the possible treatment options of this rare and highly aggressive tumor.

Retroperitoneal extra-adrenal non-Hodgkin lymphoma: An uncommon presentation.

Primary retroperitoneal non Hodgkin lymphoma is extremely rare, its diagnosis is often difficult and it may requires a time consuming and a costly diagnostic workup. We report the case of a 46-year-old patient complaining of abdominal fullness and dorsal pain, who was diagnosed with an extra-nodal non-Hodgkin lymphoma presenting as a unique and large retroperitoneal mass. The suggested diagnosis was a malignant retroperitoneal tumor and the patient underwent an excision of the tumor throw a lombotomy followed by an R-CHOP chemotherapy regimen with good outcome.
