Background: The spindle cell lipoma is a rare benign tumor that originated from subcutaneous adipose tissue. It is a slow growing lesion and may become voluminous causing the patient an aesthetic disfigure. The diagnosis is made by the histological examination combined with immunohistochemical analysis. Radiological features present a variety of description because of the proportions difference of spindle cell lipoma components, but imaging is useful to determine the mass extents. The treatment of this kind of benign tumors is surgery which must be completed without need for other therapy. Aim: This case report highlights the exceptional location of spindle cell lipoma in the soft tissues of the parotid-masseter lodge, which may raise differential diagnosis problems with a primary parotid gland tumor. Case Presentation: A 58-year-old man, with no medical history, was presenting a swelling of the parotid region, growing progressively for 6 years, without other associated sign. The patient benefited from a careful physical examination. A computed tomography and magnetic resonance imaging were carried out. Clinical and radiological findings were suggesting a benign tumor occupying the left parotid-masseter lodge. The patient went through a surgical excision of the tumor. Histological and immunohistochemical features revealed a classic shape of spindle cell lipoma. After one year of follow-up, we notice a good recovery without local recurrence. Conclusion: Surgeons and pathologists have to keep in mind the possible development of spindle cell lipoma in any subcutaneous site even if unusual one.

Secondary Hyperparathyroidism in Dialysis Patients: Short- and Long-Term Outcomes of Conservative Parathyroidectomy

引用

Open Journal of Nephrology 2024年第2期14卷 147-156页

作者： imane Saidi Sara Elmaakoul Naima Ouzeddoun Loubna Benamar Department of Nephrology-Dialysis-Renal Transplantation IbnSina Hospital Mohammed V University Rabat Morocco

Secondary hyperparathyroidism (HPT) is frequent in dialysis patients. Parathyroidectomy (PTX) is indicated for patients who failed medical therapy. We reviewed the data from 184 dialysis patients who underwent PTX between January 2015 and January 2023. We aimed to evaluate the short and long term outcomes of PTX in dialysis patients, comparing the conservative 3/4 versus 7/8 techniques in this population.166 dialysis patients with secondary HPT were included. A conservative subtotal PTX (sPTX) 7/8 was performed in 72% of patients and sPTX 3/4 in 28% of them. Severe postoperative hypocalcaemiaocurred in 45 patients (27%). Hypocalcaemia was significantly more frequent in the sPTX 7/8 group (p = 0.012). One case of persistent HPT (0.6%) and 20 cases of recurrence (12%) were diagnosed. Recurrence was more frequent in the sPTX 3/4 group (15%). No deaths were reported during the perioperative period.

Bilateral Avascular Necrosis of the Femoral Head in Renal Transplant Recipient: A Case Report

引用

Open Journal of Nephrology 2024年第2期14卷 253-261页

作者： imane Saidi Moulay Omar Lamrani Naima Ouzeddoun Tarik Bouattar Department of Nephrology-Dialysis-Renal Transplantation IbnSina University Hospital Rabat Morocco Faculty of Medicine and Pharmacy Mohammed V University Rabat Rabat Morocco Department of Traumatology IbnSina University Hospital Rabat Morocco

Osteoarticular complications are common after renal transplantation. The complications may result from the bone condition prior to transplantation or the iatrogenic effects of the treatments administered. These complications lead to significant morbidity and mortality, in addition to chronic pain and functional impairment. We report the clinical case of bilateral avascular necrosis (AVN) of the femoral head in a kidney transplant recipient. Clinical Case: 53-year-old male with a history of chronic hypertension. He underwent chronic hemodialysis for 12 months and was treated with Entecavir for chronic hepatitis B. The patient received a kidney transplant from a non-related living donor. Induction therapy included Thymoglobulin along with tapered corticosteroids, reaching a dose of 5 mg/day after 3 months, Mycophenolate mofetil (2 g/day), and Tacrolimus adjusted based on residual levels. There was good recovery of renal graft function. After six months, the patient reported bilateral hip pain and functional impairment of both lower limbs. Pelvic X-rays showed signs suggestive of bilateral AVN of the femoral heads. The diagnosis was confirmed by MRI. The patient underwent right hip drilling and total left hip replacement (THR). A right THR was performed a year later. Conclusion: AVN constitutes a frequent cause of morbidity and mortality after RT. The pathophysiology of osteonecrosis remains complex and multifactorial. We emphasize the importance of conducting a thorough assessment of bone health in patients both before and after RT.

Cerebral Glioblastoma in Renal Transplant Recipient: A Case Report

引用

Open Journal of Nephrology 2024年第1期14卷 10-16页

作者： imane Saidi Meryem Benbella Loubna Benamar Naima Ouzeddoun Tarik Bouattar Department of Nephrology Dialysis and Renal Transplantation Ibn Sina University Hospital Rabat Morocco Faculty of Medicine and Pharmacy Mohammed V University Rabat Morocco

Cancers is a leading cause of mortality among transplant recipients. The most common cancers are skin tumors. Glioblastoma is the most frequent brain tumor in adults aged 45 - 70 years. It accounts for 12% - 15% of all intracranial tumors. It is characterized by its rapid development and poor prognosis. We report the case of a cerebral glioblastoma in a kidney transplant recipient. Clinical case: Mr G.R, 44 years old caucasian patient who underwent kidney transplantation. Immunosuppressive treatment included cyclosporine, mycophenolate mofetil and methylprednisolone. Creatinine levels after transplantation remained stable at 11 mg/L (96.8 μmol/l) with an estimated glomerular filtration rate (eGFR) of 77 ml/min/1.73m2 after a 15 years of follow-up. A grade IV right fronto-callossal cerebral glioblastoma was diagnosed in our patient. EBV PCR was negative. Therefore, he underwent 25 sessions of radiotherapy combined with oral chemotherapy using temozolomide. One month later, the patient died due to cerebral edema with subfalcine herniation. Conclusion: This is a case of cerebral glioblastoma in a kidney transplant recipient, a population considered at risk for tumor development due to immunosuppressive treatment. This emphasizes the need for a lifelong surveillance and, more importantly a better balance between graft function preservation and the risks associated with immunosuppressants.

Open Journal of Nephrology 2024年第1期14卷 115-123页

作者： Meryem Benbella Zaineb Kaouiri imane Saidi Naima Ouzedoun Tarik Bouattar Department of Nephrology-Dialysis-Renal Transplantation Ibn Sina University Hospital in Rabat Rabat Morocco Faculty of Medicine and Pharmacy in Rabat Mohammed V University Rabat Morocco

Kaposi sarcoma is a neoplasm caused by human herpesvirus 8 (HHV8) that most commonly affects immunosuppressed patients. The skin is the most affected area, but other sites can be involved such as the lung, digestive tract and lymph nodes. The classical presentation involves a violaceous skin lesion that can be small or hidden, leading to a delay in diagnosis. We report a clinical case of a kidney transplant patient, who presented, 14 months after kidney transplant, with unilateral edema of the inferior member and cutaneous rash misdiagnosed and taken initially for erysipelas. The diagnosis of Kaposi’s sarcoma was retained, on a lymph node biopsy of an inguinal adenopathy. The evolution was marked by a local and general improvement after systemic chemotherapy, reducing Tacrolimus and discontinuation of Mycophenolate mofetil. Graft function remained stable during the follow-up.

Echerichia coli Infection—Associated Glomerulonephritis in a Kidney Transplant Patient: A Case Report

引用

Open Journal of Nephrology 2024年第1期14卷 81-85页

Post infectious Glomerulonephritis (PIGN) in renal allograft is a rare entity. Only a few Cases have been described in the literature. The post streptococcal glomerulonephritis is the classic example in native kidney. A wide variety of organism has been associated with PIGN in renal allograft such as Staphylococcus, Cytomegalovirus and Polyomavirus. We describe one case of Infection associated glomerulonephritis due to Echericha Coli, developed 5 years after kidney transplantation, in 47 years old female patient. The Clinical presentation was characterized by a peripheral edema and high blood pressure, and biological tests showed a nephrotic syndrome, an acute kidney injury, a consumption of Complement fractions. The renal biopsy revealed a diffuse endocapillary cell proliferation with preponderant deposits of C3. Total recovery was achieved 4 months after Methyprednisolone pulse and Cyclophasphamid with antimicrobial treatment.
