Necrotizing fasciitis caused by Serratia marcescens after venous access port implantation in a child with acute lymphoblastic leukemia.

Necrotizing fasciitis is a potentially life-threatening infection of deep skin layers and subcutaneous tissues that can easily spread across the fascia plate and is usually the result of a combined infection with anaerobic and aerobic microorganisms. The patient typically complains of excruciating pain, which is not necessarily in accordance with clinical signs. Early recognition of the condition is very important, and aggressive treatment with a combination of antibiotics and surgical procedure is crucial. We present a case of a 15-year-old girl with acute lymphoblastic leukemia who developed necrotizing fasciitis after venous access port implantation during induction chemotherapy.

Primary cutaneous cryptococcosis in a renal transplant recipient: case report.

We report a kidney transplant recipient with severe skin- and soft-tissue infection mimicking necrotising fasciitis. Patient failed to respond to empirical antibiotic therapy for presumed bacterial cellulitis. Culture of aspirate from the wound and tissue samples revealed Cryptococcus neoformans. No signs of systemic cryptococcal infection were found. After antifungal treatment and surgical intervention, complete healing was achieved. Clinical and microbiological characteristics of this patient are discussed. Our case indicates that primary cutaneous cryptococcosis must be included in the differential diagnosis of severe cellulitis in solid organ transplant recipients not responding to broad-spectrum antibiotic regimens. In our case, prompt diagnosis and treatment could dramatically modify the outcome.
