Isolated bilateral renal mucormycosis masquerading as renal abscess in an immunocompetent individual: a lesson learnt.

Paonam S, Bag S, Mavuduru RS, Agarwal MM, Mandal AK - Case Rep Urol (2014)

Bottom Line: Isolated renal mucormycosis is a rare entity in immunocompetent subjects.It is usually a rapidly progressive disease with poor prognosis but it can mimic renal abscess with a protracted course.

Mentions: Clinically, most patients with isolated renal mucormycosis present with fever, flank pain, tenderness, gross hematuria, or pyuria. Blood and urine cultures are often negative and diagnosing mucormycosis almost always requires histopathologic evidence of fungal invasion of the tissues. The biopsy should demonstrate the characteristic wide (3–25 μm in diameters), ribbon-like, aseptate (pauciseptate), thin walled hyphae branching at right angles. These organisms are often surrounded by extensive necrotic debris (Figure 2). Due to the thin wall they are weakly stained with Gomori methenamine silver and periodic acid-Schiff stain. Other fungi like Aspergillus, Fusarium, and Scedosporium may look similar to the Mucorales on biopsy. However, these molds are septate, are usually thinner, and have uniform width and dichotomous branching at acute angles. Similarly, Candida exists in yeasts and pseudohyphae forms with thinner hyphae, no true branching, and poor staining on routine hematoxylin and eosin but strong magenta on periodic acid-Schiff stain [4].
