A 74-year-old woman who had previously undergone left nephrectomy because of calculi was referred to our department with a right renal mass that was detected by computed tomography (CT) during treatment for pyelonephritis. Repeated CT showed a contrast-enhanced 4.7 cm tumor close to the renal sinus, and no metastatic lesion was detected. Sunitinib was administered as a presurgical therapy ; however, the patient experienced grade 3 neutropenia and thrombocytopenia, and sunitinib was discontinued. Sorafenib was administered 7 days after discontinuation of sunitinib ; however, the patient experienced febrile neutropenia and rash, and sorafenib was discontinued. Extracorporeal partial nephrectomy and auto-transplantation were performed 24 days after discontinuation of sorafenib. Though peri-graft abscess was suspected to be present and resolved by antibacterial therapy, severe complications were not experienced, and the patient did not require dialysis therapy after surgery. There was no evidence of recurrence at 30 months after the surgery.

We describe a case of a young female with lupus that complained about suprapubic pain, dysuria, fever and vomits, symptoms first interpreted as pyelonephritis, despite negative cultures and imaging studies showing hydroureteronephrosis with inflammatory changes. When she developed malar rash, anasarca and nephrotic syndrome, the diagnosis of lupus cystitis with stage IV nephropathy was made, and she started immunosuppressive induction treatment with three pulses of corticosteroids followed by oral prednisolone (60 mg/d) and mycophenolate (1.5 g/d). One month later she was admitted again with blood exams compatible with thrombotic microangiopathy, requiring aggressive immunosuppression and plasma exchange. After overcoming multiple complications, the patient gradually improved, and was discharged with close surveillance. This case poses the question: if the urogenital involvement had been recognized and treated in time, would it prevent the onset of lupus nephritis and other complications?

Infectious mononucleosis, a syndrome characterized by the triad of pharyngitis, fever, and lymphadenopathy, is caused in the majority of cases by Epstein-Barr virus and usually presents in adolescents and young adults. The disease is for the most part self-limited with full recovery; however, life-threatening complications can occur. Manifestations of Epstein-Barr virus associated infectious mononucleosis can be variable and at times atypical, leading to a delay in diagnosis and consequently unnecessary tests and treatment. We present a case of infectious mononucleosis from Epstein-Barr virus in a female college student who was admitted to the hospital with the initial diagnosis of pyelonephritis. This diagnosis was made based on an abnormal urinalysis, including the presence of white blood cells, red blood cells, and protein, in the setting of high fevers, cough, abdominal pain, left costovertebral tenderness, and an unexplained left neck mass. A monospot was negative two days prior. Renal involvement in Epstein-Barr virus infection is not common and bridges the spectrum from asymptomatic urinary abnormalities to acute renal failure, with acute interstitial nephritis being the most frequent pathological finding. Our patient received corticosteroids and albuterol for a worsening cough, in addition to supportive care. Despite steroid therapy, she developed a debilitating, protracted urticarial rash, also thought to be caused by the Epstein-Barr virus infection. Our case highlights the varied and complex constellation of findings sometimes seen in Epstein-Barr virus infectious mononucleosis. Like in our patient, pharyngitis, a part of the hallmark triad of symptoms characterizing infectious mononucleosis, is not always present, and the monospot may be negative. A high degree of suspicion, as well as recognition that multiple organ systems may be involved in Epstein-Barr virus associated infectious mononucleosis, is required to make the proper diagnosis.
