Cutaneous zygomycosis associated with urate panniculitis.
Cutaneous zygomycosis is being increasingly recognized as a serious and life-threatening infection in debilitated and immunosuppressed patients, including transplant patients. The organisms are morphologically distinct but difficult to grow in cultures from clinical samples. We report a case of cutaneous zygomycosis in a neonatal multi-visceral organ transplant patient, with subcutaneous panniculitis accompanied by extensive local acicular uric acid crystal deposition. Although the patient's serum uric acid was subsequently found to be in the normal range, transient hyperuricemia could not be excluded. Because we use a microwave-based processing system avoiding aqueous solutions, the crystals were maintained in the tissue sections and were shown by various methods to consist of monosodium urate. Early diagnosis combined with extensive debridement and prompt antifungal therapy resulted in a successful outcome. We have coined the term "urate panniculitis" to describe this phenomenon.[1]References
