Necrotising fasciitis of the neck and anterior chest wall

Necrotising fasciitis of the thoracic wall: a rare case with favourable outcome

Necrotising fasciitis (NF) is a severe infection of the subcutaneous tissue and fascia that can rapidly lead to sepsis and shock with high mortality rates. Its initial signs are often non-specific making it difficult for an early diagnosis to be reached. Nevertheless it is of the utmost importance to begin proper treatment including wide surgical debridement as soon as possible in order to avoid death. We present the case of a patient with NF of the thoracic wall which is a rare location for this disease but often associated with worse prognosis. Even though he progressed to septic shock within less than 24 hours of its presentation, due to early surgical management, aggressive resuscitation and intensive care support, he reached a favourable outcome. After three surgical revisions and 2 weeks in an intensive care unit, the patient was discharged from hospital 35 days after admission.

Necrotising Fasciitis: Appearances Can Be Deceptive

BACKGROUND

Necrotizing fasciitis is a potentially fatal infection of β hemolytic Group-A Streptococcus, often occurring in patients with other comorbidities, but can occur in healthy individuals as well. It commonly affects the extremities, perineum, and abdominal wall. The aim of this study was to highlight various presentations of necrotizing fasciitis in unusual anatomical sites with delayed diagnosis and treatment.

METHODS

In a retrospective analysis, seven cases of unusual presentations of necrotizing fasciitis were enrolled during a period of five years treated in a tertiary centre.

RESULTS

The patients were between 23 and 80 years. Four were males and three were females. Four out of seven were diabetic. All patients had septicemia (hypovolemic shock, with leucocytosis, thrombocytopenia and deranged coagulation parameters) on admission in the intensive care unit. All seven patients had minimal cutaneous manifestation and the remote primary pathology was diagnosed in two patients. Six patients out of seven survived and the morbid state continued in one patient in view of malignancy of rectum in one patient. The overall outcome was satisfactory in five out of seven cases.

CONCLUSION

Pain disproportionate to the local inflammation with florid constitutional symptoms should raise suspicion of necrotizing fasciitis. Early diagnosis, of stabilization of hemodynamics, emergency fasciotomy, staged debridement and the initiation of broad spectrum antibiotics reduced the morbidity and mortality. The disease may manifest with uncommon presentations and sometimes lead to the diagnosis of primary aetiology.

La fasciite nécrosante est une infection sévère, rapidement progressive, mutilante, souvent fatale du tissu sous cutané et du fascia profond. Les auteurs rapportent et discutent un rare cas de fasciite nécrosante de la paroi thoracique antérieure secondaire à une pleurésie purulente chez un diabétique. Un diagnostic précoce avec incisions multiples chirurgicales et une antibiothérapie adaptée par voie veineuse diminuent la morbidité et la mortalité causées par cette pathologie.
