Can ascending infection from bladder serve as the portal of entry for primary renal zygomycosis?

Mucormycosis is an uncommon opportunistic infection by filamentous fungi that usually develops in immunocompromised patients. Most individuals have an underlying systemic disease, such as diabetes mellitus, malignancy, uraemia, burns, renal transplant recipients and those on corticosteroid and immunosuppressive therapy. Many cases of primary renal zygomycosis with lungs serving as the portal of entry have been reported from this region. We describe two autopsy cases of renal zygomycosis where bladder appeared to be the portal of entry for the fungus.
