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.

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.

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.

Rhabdoid tumors (RTs) are a well-defined entity in the kidney or central nervous system of infants or children. However, soft-tissue involvement is uncommon. It’s an exceptional neonatal tumor of soft tissue. The imaging characteristics of this tumor are not specific. Biopsy allows diagnosis;the histomorphological characteristics of rhabdoid tumors, their immunoreactivity to epithelial markers and vimentin, and the INI-1 loss are important tools for diagnosis. RT tumors are aggressive and have a rapidly fatal clinical course in most cases. Despite multidisciplinary therapy, the survival rate is very low. We report a rare case occurring in a male neonate who presents at birth with a voluminous right axillary mass. A CT scan showed a well-limited tumor mass with lobulated contours. An ultrasound-guided biopsy was performed on day 8, showing the morphology and immunoprofile of RT. The mass showed rapid growth. The child was admitted for respiratory distress at 3 weeks. A thoraco-abdominal CT showed an increase in the size of the mass with the appearance of multiple lymph nodes and pleural, hepatic, and renal metastases. The child died two days later.
