Disseminated aspergillosis is a systemic fungal infection that may occur in previously healthy or immunocompromised patients. The condition, although rare, is being recognized with increasing frequency in persons with the human immunodeficiency virus. Clinical genitourinary involvement is unusual. We present a case of renal abscess for Aspergillus fumigatus in a patient with acquired immunodeficiency syndrome who complained of flank pain and fever.

The 15th reported case of isolated renal mucormycosis (infection of the kidney with fungus of the order Mucorales, in the absence of infection elsewhere in the body) is presented. The patient was a 36-year-old human immunodeficiency virus-infected man, actively using iv drugs, who suffered 6 wk of flank pain and fever before diagnosis was made by percutaneous renal biopsy. He received 4 months of amphotericin B treatment, then no therapy for 6 months before dying with no evidence of mucormycosis. Isolated renal mucormycosis should be suspected in those with an underlying immunocompromising illness or history of iv drug use who have persistent flank pain and fever, but sterile urine cultures. Computed tomographic scanning with contrast should then be performed; findings of severe inflammation or bacterial infection, despite an indolent clinical course with sterile or nondiagnostic urine and blood cultures, are suggestive of isolated renal mucormycosis, and renal biopsy under computed tomographic guidance should be performed, despite the potential risk of disseminated infection. Although our patient was treated with amphotericin B alone, nephrectomy with or without amphotericin B therapy appears to be more likely to cure infection and relieve pain and constitutional symptoms.

We report a case of staghorn nephrolithiasis that evolved into xanthogranulomatous pyelonephritis with perinephric abscess, nephrobronchial fistula, and lung abscess. The patient was an intravenous drug abuser who tested positive for human immunodeficiency virus, without evidence of acquired immunodeficiency syndrome. He presented with a 2-month history of untreated repeated episodes of left flank pain and hyperpyrexia. Treatment involved left nephrectomy, debridement of abscess, tube drainage, and intravenous antibiotics. The patient illustrates the need to consider untreated nephrolitiasis as a predisposing factor for pulmonary complications.

Indinavir sulfate has been reported to cause asymptomatic crystalluria and nephrolithiasis in patients with human immunodeficiency virus (HIV) infection. Patients taking indinavir may present with asymptomatic crystalluria, nephrolithiasis with frank renal colic and obstruction, flank pain in the absence of nephrolithiasis, and dysuria or urgency. Asymptomatic crystalluria has been described as benign. Discontinuation of the drug has not been recommended in the absence of nephrolithiasis. We report two HIV-positive patients receiving indinavir who developed acute interstitial nephritis with foreign body giant cell reaction on renal biopsies. Both patients had asymptomatic crystalluria, although crystals were associated with clumps of white blood cells (WBCs) on urinalysis in one patient. Both cases show that the inflammatory response was significant enough to lead to tubular injury and acute renal impairment. Our findings suggest that asymptomatic crystalluria attributable to indinavir may illicit an inflammatory response with acute renal insufficiency, warranting monitoring of renal function, especially in patients with crystalluria.

Indinavir is a well-known cause of crystal-induced acute renal failure, dysuria and flank pain, and nephrolithiasis. Recently a more insidious tubulointerstitial lesion has been recognized as secondary to the drug. We report a case of a hepatitis C-positive patient on long-term indinavir therapy for human immunodeficiency virus (HIV) who developed a slowly progressive rise in serum creatinine. Renal biopsy revealed a diffuse interstitial infiltrate with numerous eosinophils and scarring. The tubules showed focal necrosis and dilation with elongated crystals present within their lumina. The elevated serum creatinine decreased to a new baseline over several months with the discontinuation of indinavir. We review the literature of renal syndromes associated with indinavir focusing on chronic progressive tubulointerstitial injury and speculate on risk factors and potential mechanisms of indinavir-induced renal injury.

Extramedullary plasmacytoma (EMP) is a rare malignant tumor that is characterized by a malignant plasma cell neoplasm. Such neoplasms in human immunodeficiency virus (HIV)-infected patients are extremely rare. To the best of our knowledge, the present study describes the first case of a solitary adrenal EMP in a patient with HIV. A 35-year-old male who had been diagnosed with HIV 3 months previously presented with a 2-week history of intermittent right flank pain. Abdominal computed tomography revealed a soft-tissue density mass in the right adrenal gland area. The patient subsequently underwent a retroperitoneal laparoscopic adrenalectomy. Post-operative pathological diagnosis revealed a solitary EMP. Although the patient refused to undergo post-operative radiotherapy and chemotherapy, no recurrence was detected after 2 years of follow-up. The present case illustrates the fact that this rare type of solitary EMP associated with acquired immune deficiency syndrome (AIDS) can occur in the adrenal glands, and that retroperitoneal laparoscopic resection of the tumor may be a good method to manage this condition. In addition, although rare, solitary EMP should be considered in the differential diagnosis of an adrenal mass in HIV-infected patients.

BACKGROUND Leiomyosarcoma is the most common primary malignancy of the inferior vena cava (IVC), and represents approximately 10% of primary retroperitoneal sarcomas. Leiomyosarcoma presents with non-specific symptoms, including abdominal pain or back pain. There is an increased incidence in immunosuppressed individuals. CASE REPORT An unusual presentation of IVC leiomyosarcoma is reported in a 46-year-old female patient infected with human immunodeficiency virus (HIV) who was on highly active antiretroviral therapy (HAART) and who had a normal CD4 count of 934, who presented with back pain. Magnetic resonance imaging (MRI) of the lumbar spine showed a mass of the IVC. Initial computed tomography (CT)-guided biopsy of the IVC mass was non-diagnostic. An IVC filter was inserted, and the patient was discharged home, but 20 days later, she returned to the hospital with worsening right flank pain. Laboratory tests showed acute renal failure, and a repeat CT scan showed IVC thrombus extending 5 cm superiorly. When compared with the previous CT, there was an extension of thrombus into both renal veins. Histopathology of a transjugular needle core biopsy showed a moderately differentiated leiomyosarcoma. The patient was transferred to a multidisciplinary sarcoma center for surgical resection, chemotherapy, and radiation therapy. CONCLUSIONS This report is of a rare case of IVC leiomyosarcoma in a middle-aged HIV-positive woman with a normal CD4 count. Leiomyosarcoma of the IVC is extremely rare, is often detected when advanced, and has a poor prognosis. This case report describes the clinical, imaging, surgical and histopathological findings of leiomyosarcoma of the IVC.

Biliary and urinary obstructions can be managed endoscopically or cystoscopically, surgically or by percutansous intervention or drainage. If the obtructed system is infected, emergent decompression is needed. Early recognition and treatment is paramount in both conditions. Acute cholangitis can present many different ways, from mild symptoms to fulminant sepsis. It is usually a result of ascending bacterial colonization and biliary obstruction resulting in bacterial overgrowth. Therefore, those patients with recent biliary instrumentation or previous biliary modification are at higher risk. Charcot's triad of fever, right upper quadrant abdominal pain, and jaundice is only seen in 50%-70% of patients. Fever is seen in over 90% of cases, pain is seen in 70% of cases, and jaundice is seen in 60% of cases. Altered mental status and hypotension are associated with severe cases. All 5 symptoms of fever, right upper quadrant abdominal pain, jaundice, altered mental status, and hypotension are referred to as Reynold's Pentad. Acute pyonephrosis can also present many different ways, from minimal symptoms to fulminant sepsis. Fever, chills, and flank pain are the classic symptoms, although some patients may be relatively asymptomatic. Pyonephrosis may present with a classic triad of fever, flank pain, and hydronephrosis, or simply hydronephrosis and sepsis. Pyonephrosis usually occurs as a result of urinary obstruction with either an ascending infection of the urinary tract or hematogenous spread of a bacterial pathogen as the culprit. Up to 75% of cases are related to urinary stone disease. Patients are at increased risk for pyonephrosis when they haven anatomic urinary tract obstruction, certain chronic diseases (diabetes meliitus and AIDS), or are immunosuppressed due to immunodeficiency or medications, (chronic steroid therapy).

We describe a rare case of methicillin-sensitive staphylococcus aureus (MSSA) septicemia with metastatic spread leading to pulmonary septic emboli, sub-capsular perinephric renal abscess, prostatic abscess, and intramuscular calf and gluteal abscess in a 48-year-old male with uncontrolled diabetes mellitus (Hemoglobin A1c of 15.2). The patient developed right lower extremity pain after a session of acupuncture followed by a three-week history of fevers, chills, abdominal pain, left flank pain, and urinary retention. Evaluation was negative for endocarditis, intracardiac shunt, intravenous drug usage, or immunodeficiency.
