Ecthyma gangrenosum: A case report in a child with acute lymphoblastic leukaemia.

Aim: We present a case of Ecthyma gangrenosum (EG) affecting left thigh in a child with acute lymphoblastic leukaemia (ALL) with an aim to raise awareness about this condition. Case presentation: A 7-year-old female child who presented with lethargy, pallor and lumps to inner lip was diagnosed with B-cell precursor ALL. She was started on treatment as per UKALL 2011 guidelines Regime B. On day 28, she developed neutropenic sepsis along with a new lesion in her left thigh. She was started on intravenous Meropenum, Gentamicin and Caspofungin. The clinical diagnosis of EG was made based on lesion progression, positive blood and wound swab & tissue cultures for Pseudomonas aeruginosa and patient's immunocompromised status. The wound healed with secondary intention following debridement. We present a series of photographs to demonstrate her remarkable improvement. Discussion: EG occurs in 1-30% of cases of Pseudomonas sepsis; other bacteria and fungi can be associated with this condition. It is identified more in oncology patients as seen in our patient. A multidisciplinary team approach should be provided in 3 stages with empirical antibiotics, followed by targeted antibiotics or antifungals & surgical debridement. Our patient was treated in similar fashion and made a good recovery. Conclusion: It is a rare skin condition associated with a high mortality. We suggest all clinicians to be vigilant about this condition to be able to provide accurate diagnosis and prompt treatment to improve the overall prognosis.

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.

An Infant with Measles Developed Ecthyma Gangrenosum Caused by Coagulase-Negative Staphylococcus: A Rare Case Report from Somalia.

Introduction and Importance: Ecthyma gangrenosum is a skin lesion that can be caused by either bacterial hematogenous seeding or a primary skin infection. Despite being the most frequent causal agent, Pseudomonas aeruginosa is not the only bacteria that has been involved. Other types of bacteria may also be implicated in the etiology of EG: cocci bacteria, both gram-positive and gram-negative. Case Presentation: Here, we report the case of a 10-month-old male infant who developed ecthyma gangrenosum after a measles infection. At the time of admission, the patient had a high fever of about 40.3°C and appeared conscious. Physical examination revealed several skin lesions that were in various stages of development and appeared as nodules with a central crust and round, ulcerated, necrotic papules in the face, chest, and upper extremities. Laboratory tests showed CRP of 25 mg/l, LDH of 579 U/L, WBC of 15.06 × 1000/mm3, and absolute neutrophils of 1930/mm3 (12.8%). The result of the culture showed coagulase-negative Staphylococcus. According to the drug susceptibility test results, intravenous Vancomycin (20 mg/kg per dose, 3 times daily) should be started. A coagulase-negative Staphylococcus was eliminated as a result of this defervescence. The necrotic lesion was surgically removed from the patient. Clinical Discussion: Ecthyma gangrenosum is the all-over-the-body cutaneous manifestation of pseudomonas infection in sepsis patients. Patients who suffer from severe illnesses. Immune deficiencies commonly increase the chance of acquiring EG. Our patient had a history of measles, which led to neutropenia before developing EG. The management of ecthyma gangrenosum requires early identification and antimicrobial treatment. Conclusion: We describe a measles patient who developed coagulase-negative Staphylococcus ecthyma gangrenosum and had good results from both surgical debridement and systemic antibiotics. Our case serves as an example of the uncommon presentation of ecthyma gangrenosum. This example emphasizes the value of an early diagnosis and vigorous antimicrobial therapy in cases where ecthyma gangrenosum is clinically suspected.

Periocular ecthyma gangrenosum with Pseudomonas septicemia in an infant: A case report.

Ecthyma gangrenosum is a skin manifestation of fatal septicemia. We report a case of periocular ecthyma gangrenosum, which is an uncommonly infected area and rarely reported in infants. A 1-month-old female infant with periocular ecthyma gangrenosum presented with a high-grade fever and acute left medial canthus of the eyelid swelling and erythema. Hemoculture at 6 h confirmed Pseudomonas aeruginosa infection. Intravenous and topical antibiotics were administered. Daily dressing of the wound and noninvasive bedside escharectomy were performed. Cosmetically acceptable scar was achieved without additional surgery. The patient was considered to have congenital neutropenia due to persistent neutropenia and severe skin and mucosal infections in her first year of life. Noninvasive debridement of the wound reduces the risk of exposure keratitis, lacrimal drainage pathway damage, and the need for further surgical reconstruction. The cause of compromised immunity in infants with ecthyma gangrenosum should be investigated, and intensive follow-up is recommended.

Clinicopathologic features of ecthyma gangrenosum: a single integrated health system cohort.

Ecthyma gangrenosum is an uncommon cutaneous eruption that can initially present with painless macules, which rapidly evolve into necrotic ulcers. This study sought to characterize clinicopathologic features of ecthyma gangrenosum from a single integrated health system. Our cohort consisted of 82 individuals diagnosed with ecthyma gangrenosum. Lesions were most commonly found in the lower extremities (55%) and the truncal region (20%). A wide variety of fungal and bacterial etiologies were found among our cohort. The majority of patients with EG were immunocompromised (79%) and 38% of patients also experienced sepsis. The mortality rate seen in our cohort was approximately 34%. No statistical differences in mortality outcome due to EG related complications were seen between pathogen etiology, and distribution or location of lesions. Patients who were septic or immunocompromised died more frequently than non-septic or immunocompetent patients, suggesting poorer prognosis.

Shanghai Fever: Not Only an Asian Disease.

Objectives: To describe a case of Shanghai fever disease and to analyze other published reports in non-Asiatic countries, defining clinical characteristics and highlighting that this is not only an Asian disease. Study design: A computerized search without language restriction was conducted using PubMed and Scopus; all references listed were hand-searched to identify any other relevant literature. An article was considered eligible for inclusion in the systematic review if it reported cases with Shanghai fever described in non-Asiatic countries. Our case was also included in the analysis. Results: Ten articles reporting 10 cases of Shanghai fever disease were considered. Fever, diarrhea and ecthyma gangrenosum were the most frequent symptoms observed. Blood was the most common site of isolation for Pseudomonas aeruginosa. Three patients underwent surgery due to necrotizing enteritis and intestinal perforation. Meningitis was documented in one case. None of the patients received antipseudomonal antibiotics within 24 h of admission. The outcome was good in nine cases; only one patient died due to multiple organ failure from Pseudomonas sepsis. No common primary immune deficiency was identified in these patients. Extremely young age (<1 year) was the only host factor predisposing to Shanghai fever. Conclusions: It is important to shed light on this disease in non-Asiatic countries and take into account that it can also affect healthy children. Pediatricians, therefore, should consider Shanghai fever among diagnoses in children with community-onset diarrhea, fever and skin lesions suggestive of ecthyma gangrenosum to start an appropriate treatment sooner and to reduce the mortality in these children.

Multidisciplinary management of disseminated Exophiala dermatitidis mycosis in an infant with mixed phenotype acute leukemia: a case report.

BACKGROUND: Exophiala dermatitidis is a dematiaceous fungus isolated from various environmental sources. Systemic E. dermatitidis infections can lead to fatal outcomes, and treatment has not yet been standardized. Although E. dermatitidis is also known to cause cutaneous infection, it has not been previously reported to appear as ecthyma gangrenosum (EG), an uncommon cutaneous lesion in neutropenic patients that is mainly caused by Pseudomonas aeruginosa. CASE PRESENTATION: A 2-month-old male infant with mixed-phenotype acute leukemia presented with prolonged fever unresponsive to antibacterial and antifungal agents during myelosuppression due to remission induction therapy. He also presented with skin lesions on the left wrist and left lower quadrant of the abdomen. The abdominal lesion gradually turned black and necrotic, which was consistent with the findings of the EG. E. dermatitidis was isolated from the blood, stool, wrist skin, and endotracheal aspirate. During hematopoietic recovery, consolidation in both lungs was evident. Multiagent antifungal treatment failed to eliminate E. dermatitidis from blood. In order to salvage the central venous catheter, ethanol lock therapy (ELT) was adopted, following which the blood culture became negative. The abdominal lesion that evolved as a necrotic mass connecting the small intestine and subcutaneous tissue adjacent to the skin was surgically resected. After these interventions, the general condition improved. CONCLUSION: Disseminated E. dermatitidis mycosis in the neutropenic infant was successfully managed with a multidisciplinary treatment consisting of multiagent antifungal treatment, ELT, and surgery.

Ecthyma gangrenosum and severe neutropenic sepsis caused by Staphylococcus aureus infection in a previously healthy child: a case report.

Ecthyma gangrenosum (EG) is a potentially lethal skin infection mainly caused by Pseudomonas aeruginosa, but other causative pathogens have also been reported. EG usually occurs locally and often arises in immunocompromised patients. The fatality rate can be extremely high if a systemic infection leading to sepsis occurs. EG and severe sepsis caused by Staphylococcus aureus infection are extremely rare in healthy children. However, upon occurrence, disease progression can be rapid, and the mortality rate is high. This current case report describes a previously healthy child with no underlying diseases who developed EG in the facial and perianal regions following S. aureus infection. The infection rapidly progressed to sepsis, septic shock, and persistent severe neutropenia. The patient also developed drug-resistant bacterial infections that spread rapidly and resulted in multiorgan failure. The patient was treated with antibiotics, but she died of organ failure despite extracorporeal membrane oxygenation support. EG caused by S. aureus has the potential to progress rapidly, leading to septic shock and severe neutropenia. Patients should be identified at an early stage and promptly treated with antibiotics. However, the improvement of neutropenia and prevention of secondary infections remain the focus of our research.

Ecthyma Gangrenosum Secondary to Methicillin-Sensitive Staphylococcus aureus in an Atopic Child with Transient Neutropenia: A Case Report and Review of the Literature.

In addition to Pseudomonas aeruginosa, other organisms including Staphylococcus aureus have been reported to have associations with ecthyma gangrenosum (EG). There are very limited reports of Staphylococcus aureus EG causing systemic symptoms in an immunocompetent child. We present the case of an atopic child with transient neutropenia developing characteristic skin lesions of EG. Culture of the skin wounds yielded methicillin-susceptible Staphylococcus aureus (MSSA), and incisional biopsy of the skin lesions revealed aggregates of Gram-positive cocci at the subepidermal area and necrotic vasculitis but without perivascular bacterial invasion. In the literature review, seven cases of Staphylococcus aureus EG were reported, and only two were pediatric cases. From this case, we emphasize the importance of early culturing for microorganisms in cases presenting with EG. When toxin-mediated systemic symptoms accompany EG-like skin lesions, MSSA should be considered in an atopic child with transient neutropenia.

Successful management of colistin- and carbapenem-resistant Klebsiella pneumoniae-associated ecthyma gangrenosum in acute myeloid leukemia: A rare complication.

Pseudomonal ecthyma gangrenosum is a well-known condition in immunosuppressed patients. However, ecthyma gangrenosum associated with Klebsiella pneumoniae is a rare entity that requires early recognition and optimal antibiotic and surgical management. We herein report the first case of colistin & carbapenem-resistant Klebsiella pneumoniae ecthyma gangrenosum in an acute myeloid leukemia patient. A 30-year-old female with acute myeloid leukemia received induction chemotherapy at the National Institute of Blood Diseases and Bone Marrow Transplantation hospital. Post-chemotherapy, she developed fever and a necrotic erythematous papule on right forearm. Colistin-susceptible carbapenem-resistant Klebsiella pneumoniae was isolated in cultures. Susceptibility testing was performed by microbroth dilution method. Worsening necrotic lesion prompted surgical debridement. Histopathology of debrided tissue revealed necrotic inflammation, and tissue cultures grew colistin-resistant carbapenem-resistant Klebsiella pneumoniae (colistin minimum inhibitory concentration >4 µg/mL). We speculate that colistin resistance was acquired due to impaired antibiotic penetration in necrotic nidus. A higher incidence of carbapenem-resistant Klebsiella pneumoniae-associated ecthyma gangrenosum is anticipated in hem-oncology patients, and timely diagnosis, appropriate antibiotics, and surgical debridement remain the only potential cure.

Double atypical co-infection in ecthyma gangrenosum: a peculiar case report.

Introduction: Ecthyma gangrenosum (EG) is a rare cutaneous manifestation commonly associated with Pseudomonas aeruginosa infection in immunocompromised individuals. Additionally, different bacterial and fungal pathogens have also been identified. However, co-infection on EG lesions has never been reported before. Case report: We present the case of a seven-year-old female Asian patient who initially was diagnosed with febrile neutropenia. Initially, on the sixth day of admission, dermatological status revealed multiple painless erythematous macules on the face and arms together with persistent fever followed by evolution to multiple black, deep-seated, and large central eschars and early identification of Pseudomonas aeruginosa in the blood culture. Further evaluation revealed the development of EG with XDR Acinetobacter baumannii and Aspergillus spp. isolated from the samples harvested intraoperatively. Conclusions: Specific identification of etiological agents will serve its importance for early diagnosis, aggressive antibiotic treatment, and/or surgical intervention to improve the prognosis.

Prevalence and clinical features of secondary skin lesions in septic patients with bloodstream infections.

Cutaneous manifestations developed in the course of sepsis are poorly documented in the medical literature beyond those related to specific pathogens or classical clinical pictures such as purpura fulminans or ecthyma gangrenosum. The objective of this study was to determine the overall prevalence of sepsis-related skin findings and evaluate their possible impact on the prognosis of septic patients. Single-centre, retrospective study of septic patients with documented bloodstream infections admitted in a tertiary hospital during 2019. Primary skin and soft tissue infections, and non-sepsis-related skin conditions diagnosed during hospital admission were excluded. Unselected sample of 320 episodes of sepsis in 265 patients. Secondary skin lesions were documented in 57 sepsis episodes (17.8%) in 47 patients. Purpura (petechiae/ecchymosis) was the most frequent cutaneous finding in septic patients (35.5%), with non-acral involvement in more than one-third of the episodes (38.5%), followed by skin and soft tissue erythema/oedema (25.8%) and maculopapular rashes (11.3%). Secondary skin lesions occurred more frequently in sepsis of respiratory (p = 0.027) and skin and soft tissue (p = 0.018) origin, as well as in sepsis caused by Pseudomonas aeruginosa and Stenotrophomonas maltophilia (p = 0.001). Mean hospital stay was 38.58 days and sepsis-related mortality 21.1%. Our results suggest that cutaneous involvement in the course of sepsis is frequent, with purpura being the main clinical sign. The semiology described in this study, easily identifiable by non-dermatologists, should alert clinicians to the potential unfavourable course of these patients.

A Challenging Cutaneous Lesion in a Patient With Chronic Idiopathic Neutropenia.

Ecthyma gangrenosum (EG) is an uncommon necrotizing vasculitis that affects mainly immunocompromised and burn patients, and it is frequently associated with Pseudomonas aeruginosa bacteremia. However, cases of EG with other related pathogens and cases of EG affecting immunocompetent hosts have also been described in the literature. Besides, less common cases of EG without bacteremia have been reported. Herein, we describe a rare case of EG due to Pseudomonas aeruginosa without bacteremia in a patient with chronic idiopathic neutropenia (CIN). Considering the high mortality rate associated with EG, early diagnosis and appropriate effective treatment are crucial.

Ectima gangrenoso en el paciente inmunocomprometido: debut leucemia aguda

El Ectima gangrenoso es un trastorno infeccioso infrecuente, clásicamente relacionado a bacteriemia, descrito principalmente en poblaciones inmunodeprimidas. Se asocia con la sepsis y bacteriemia por P. aeruginosa en pacientes inmunodeprimidos, incluidos aquellos con neutropenia o inmunodeficiencias, también se han descrito casos por hongos filamentosos y levaduras. Se ha observado en aproximadamente un 1,3-3 % de los casos de bacteriemia por P. Aeruginosa1. Se ha descrito ectima en pacientes con déficit en su inmunidad2, como en el caso que se describe a continuación. El Ectima puede presentarse como lesión única o múltiple, caracterizadas por máculas eritematosas que progresan a vesículas, bullas o pústula, evolucionando hasta la necrosis central con halo eritematoso. Se presenta el caso de un paciente con Ectima Gangrenoso, refractario inicialmente a tratamiento, que evolucionó con empeoramiento progresivo, presentándose en el hemograma hiperleucocitosis asociado a anemia y trombopenia, con diagnóstico ulterior de Leucemia Mieloide Aguda.

Ecthyma gangrenosum is an uncommon infectious disorder classically associated with bacteremia and found mainly in immunocompromised populations. It is associated with sepsis and Pseudomonas aeruginosa bacteremia in immunocompromised patients, including those with neutropenia or immune deficiencies. There have also been cases caused by filamentous fungi and yeasts. It has been seen in approximately 1.3 ­ 3% of Pseudomonas aeruginosa bacteremias. Ecthyma has been reported in immune-deficient patients, as in the case described below. Ecthyma can present with a single or multiple lesions with erythematous macules progressing to vesicles, bullas or pustules, which develop central necrosis with an erythematous halo. We present the case of a patient, later diagnosed with Acute Myeloid Leukemia, with ecthyma gangrenosum, initially refractory to treatment, which worsened progressively, presenting hyperleukocytosis associated with anemia and thrombocytopenia in the whole blood count.

Ecthyma gangrenosum as a serious complication of Pseudomonas aeruginosa infection in departments of paediatric oncology.

In most cases ecthyma gangrenosum is a consequence of Pseudomonas aeruginosa bloodstream infection in immunodeficient patients. This bacterium is characterized by multi-drug resistance and has a number of mechanisms that allow it to survive even in extreme conditions. The disease is characterized by an aggressive course involving the skin and mucous membranes, leading to ulceration with signs of necrosis within 12 to 24 h. Treatment includes targeted antibiotic therapy and surgical cleansing of the wound. If the perianal area is occupied, a colostomy may be performed. Prevention of bacterial infections involves taking special precautions when handling a patient with immunodeficiency.

Ecthyma gangrenosum: a rare manifestation of Stenotrophomonas maltophilia infection in acute myelogenous leukemia patient.

Ecthyma gangrenosum is a cutaneous infection typically associated with Pseudomonas aeruginosa. However, it is rarely caused by Stenotrophomonas maltophilia which might be overlooked leading to devastating consequences. We describe this case to avoid delays in the diagnosis and treatment of this aggressive infection, especially in immunocompromised patients.
