Extensive perineal ecthyma gangrenosum in leukocyte adhesion deficiency type 1 associated with Staphylococcus hominis bacteremia.

Leukocyte adhesion deficiency (LAD), a disorder of neutrophil function, is characterized by a defect in leukocyte adhesion to the endothelium. Recurrent infections in the skin, soft tissue, gingiva, and lungs due to Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella sp. are common in these patients. Ecthyma gangrenosum (EG) is an ulcer of skin and subcutaneous tissue with a black eschar and surrounding erythematous halo secondary to a bacterial infection. Here, we report an unusual presentation of LAD type-1 with extensive EG of perineum secondary to Staphylococcus hominis bacteremia treated successfully with combination of granulocyte transfusion and diversion colostomy.

A fatal case of Ecthyma Gangrenosum in a critically ill and immunocompromised patient.

INTRODUCTION: This brief picture-oriented case report focuses on typical skin lesions in a patient who developed Ecthyma gangrenosum and pseudomonal sepsis after extensive immunosuppressive therapy for Pemphigus vulgaris. CASE PRESENTATION: The patient was immunosuppressed with high doses of glucocorticoids and azathioprine; the follow-up after the treatment was not carried out well due to the pandemic conditions and because the patient herself got a Covid infection, which resulted in the development of pseudomonal sepsis and Ecthyma gangrenosum. The outcome was fatal despite extensive broad-spectrum antibiotic therapy, plasmapheresis, and intravenous immunoglobulins. CONCLUSIONS: Infections with Pseudomonas aeruginosa have become a real concern in hospital-acquired infections, especially in critically ill and immunocompromised patients, because of multi-drug resistance in the first place.

Hemorrhagic Vesiculobullous Lesions of Ecthyma Gangrenosum in a Diabetic Patient with Myelofibrosis: A Rare Presentation of Septic Shock without Pseudomonas aeruginosa Bacteremia.

BACKGROUND Ecthyma gangrenosum is a rare skin lesion associated with Pseudomonas aeruginosa, an aerobic gram-negative opportunistic bacterial pathogen. In non-bacteremia patients, sepsis is not a common complication. Immunocompromised patients are more commonly affected. If diagnosis and therapy are delayed, the mortality rate is 18-96%. This report is of a 52-year-old man with diabetes mellitus and myelofibrosis presenting with hemorrhagic vesiculobullous lesions of ecthyma gangrenosum on the upper and lower extremities, oral mucosa, and anogenital area with, interestingly, no associated Pseudomonas aeruginosa bacteremia. CASE REPORT A 52-year-old diabetes patient with myelofibrosis presented with hemorrhagic vesiculobullous and necrotic eschar-covered erosions over the upper and lower extremities, oral mucosa, and anogenital area. Although he appeared septic looking initially, with signs of end-stage organ failure, and he was later determined to have septic shock, the clinical diagnosis was not possible without a positive culture swab of the cutaneous lesions showing growth of Pseudomonas aeruginosa. The diagnosis of cutaneous ecthyma gangrenosum-induced septic shock was confirmed, though bacteremia was not detected. This patient was successfully managed with the early initiation of proper antibiotics. CONCLUSIONS Early detection and vigilance when confronted with the clinical presentation of ecthyma gangrenosum are a vital part of patient management to reduce the high mortality risk of the disease. Although bacteremia is associated with a high risk for fatalities, cutaneous ecthyma gangrenosum can be complicated by septic shock and serious adverse events. The involvement of multidisciplinary teams in patient management is an essential aspect of ecthyma gangrenosum disease management.

Moraxella nonliquefaciens-Associated Ecthyma Gangrenosum in a Pediatric Patient With Cancer.

ABSTRACT: In this brief report, we describe a 16-year-old patient with pre-B-cell acute lymphoblastic leukemia on chemotherapy who presented to the emergency department with a fever and "bruise-like" area on his left forearm. Empiric antibiotic therapy was initiated, and initial tissue biopsy demonstrated findings consistent with ecthyma gangrenosum. On day 4 of admission, initial blood cultures grew Moraxella nonliquefaciens, and targeted antibiotic therapy was initiated and continued for a total of 21 days. The patient was discharged after 6 days of in-patient therapy and made a full recovery. M. nonliquefaciens has been reported to be associated with multiple types of infection, but no cases of M. nonliquefaciens-associated ecthyma gangrenosum were identified in the literature review for this report. Given this unique case and the empiric risks and broad differential associated with cutaneous manifestations in immunocompromised patients, obtaining a skin biopsy for histological examination is imperative for diagnostic workup.

Ecthyma Gangrenosum in Children With Cancer: Diagnosis at a Glance: A Retrospective Study From the Infection Working Group of Italian Pediatric Hematology Oncology Association.

BACKGROUND: To depict ecthyma gangrenosum (EG) clinical presentation and evolution in a large multicenter pediatric retrospective collection of children with malignancies or bone marrow failure syndromes, to facilitate early diagnosis. METHODS: EG episodes diagnosed in the period 2009-2019 were identified by a retrospective review of clinical charts at centers belonging to the Italian Pediatric Hematology Oncology Association. RESULTS: Thirty-eight cases of EG occurring in children (male/female 16/22; median age 5.2 years) with hematologic malignancy (29), allogeneic stem cell transplantation (2) or relapsed/refractory solid tumor (3) were collected. The involved sites were: perineal region (19), limbs (10), trunk (6), head and the iliac crest (3). Bacteremia was present in 22 patients. Overall, the germs isolated were Pseudomonas aeruginosa (30), Stenotrophomonas maltophilia (3) and Escherichia coli (1); 31% of them were multidrug-resistant. All patients received antibacterial treatment, while surgery was performed in 24 patients (63.1%). Predisposing underlying conditions for EG were severe neutropenia (97.3%), corticosteroid treatment (71%) and iatrogenic diabetes (23.7%). All patients recovered, but EG recurred in 5 patients. Nine patients (24%) showed sequelae (deep scars, with muscle atrophy in 2). Four patients (10.5%) died, 1 due to relapse of EG with Carbapenem-resistant Enterobacteriaceae co-infection and 3 due to the progression of the underlying disease. CONCLUSIONS: EG requires early recognition and a proper and timely treatment to obtain the recovery and to avoid larger necrotic lesions, eventually evolving in scarring sequelae.

Common Cutaneous Infections: Patient Presentation, Clinical Course, and Treatment Options.

This evidence-based review highlights cutaneous infections of bacterial, viral, and fungal origin that are frequently encountered by clinicians in all fields of practice. With a focus on treatment options and management, the scope of this article is to serve as a reference for physicians, regardless of field of specialty, as they encounter these pathogens in clinical practice.
