Atypical Presentation of Escherichia coli Monomicrobial Necrotizing Fasciitis in a Renal Transplant Patient: A Case Report.

Skin and soft tissue infections (SSTIs) are one of most frequent infectious causes for referral to the emergency department and one of the most frequent infectious causes of hospital admissions. Escherichia coli, the most commonly occurring gram-negative pathogen involved in these infections, contributes to about 7% of all SSTIs cases where gram-positive organisms reign dominant. Patients are more susceptible to these gram-negative SSTIs if they are neutropenic, have hematologic malignancies, have undergone solid organ or hematopoietic transplantation, or have cirrhotic liver disease. Due to their immunocompromised state, the prognosis is very poor and not well understood. We report a case of an atypical presentation of an E coli monomicrobial necrotizing fasciitis in a renal transplant patient. Our findings support improved mortality with rapid aggressive interventions, such as amputation, in immunocompromised patients.
