ABSTRACT
ABSTRACT Rhinocerebral and pulmonary mucormycosis are the main manifestations of mucormycosis; however, disseminated pulmonary associated with renal mucormycosis is rarely reported. In this paper, we report a rare fatal case of disseminated pulmonary and renal mucormycosis caused by Rhizopus microsporus in a 50-year-old man with poorly controlled hypertension, type 2 diabetes, and prolonged use of corticosteroids for the treatment of his reiterative gouty arthritis. In this patient, the use of corticosteroids and poorly controlled diabetes were considered underlying risk factor for his disseminated mucormycosis, along with acute renal dysfunction, suggesting the need for clinical suspicion of disseminated pulmonary and renal mucormycosis in hospitalized patients with poorly controlled diabetes and immunocompromised host.
ABSTRACT
Mucormycosis is a rare, opportunistic, highly aggressive, fungal infection primarily noted in immunocompromised individuals. Isolated involvement of any organ is rare in general. Isolated renal involvement is unusual, with only a few cases reported in literature to date. We present a rare case of isolated renal mucormycosis successfully managed with systemic anti-fungal therapy and nephron sparing surgery.
ABSTRACT
Mucormycosis is a group of clinical syndromes resulting from infection by one of a group of related filamentous fungi. It is an opportunistic fungal infection that rarely occurs in immunocompetent individual. Isolated involvement of any organ is rare and only a few cases of renal mucormycosis have been reported. We present a case report of atypical presentation of a case of renal mucormycosis in a healthy adult with no predisposing factors. A 48 year non diabetic immunocompetent patient underwent right nephrectomy for painful non-functioning kidney. Biopsy showed chronic pyelonephritis with broad non-septate hyphae suggestive of mucormycosis. Post op followup of patient is normal. Mucormycosis of kidney causes extensive infarction and necrosis due to direct angioinvasion and vascular thrombosis leading to fulminant acute renal failure. The disease mimics pyogenic infection leading to delay in diagnosis and hence resulting in high mortality. High index of suspicion is needed for early diagnosis. Urine and blood cultures are usually sterile. Characteristic CT findings include diffuse enlargement of the kidney with absence of contrast excretion and multiple low-density areas in the renal parenchyma representing fungal abscess. Whenever suspected, FNAC or biopsy is strongly advocated as no imaging can confirm the diagnosis. Nephrectomy or debridement of necrotic tissue along with IV Amphotericin B consist the principal treatment. Renal mucormycosis presenting an indolent course and found incidentally after nephrectomy is extremely rare. In an incidentally found mucormycosis, the role of further investigations to find the source and the role of antifungals have to be further studied.
ABSTRACT
La mucormicosis es una infección causada por hongos de la clase Zygomycetes. Existen varias formas de presentación clínica, siendo las más comunes la rinocerebral y la pulmonar. La mucormicosis renal aislada es un tipo de mucormicosis muy poco frecuente hasta el momento; se han reportado 25 casos en la literatura. Se presenta el caso de una paciente con leucemia aguda que desarrolló mucormicosis renal aislada, y se revisa la literatura.
Mucormycosis is an infection caused by a class Zygomycetes fungi. The rhinocerebral and pulmonary are the most common clinical presentations. Renal mucormycosis is a very rare form. To date, only 25 cases have been reported in the literature. We describe the case of a patient with leukemia who developed isolated renal mucormycosis and review the literature.
