Introduction:
Necrotizing fasciitis is an uncommon infection characterized by a necrotic infection that rapidly diffuse along the fascia and progresses to systemic sepsis. The combined occurrence of necrotizing fasciitis of the chest wall and acute appendicitis is extremely unusual.
Case Presentation:
A 27-year-old man without any significant medical history presented to the emergency department, in the postoperative course of a laparotomy for perforated acute appendicitis, with septic shock and a large erythematous region over the right abdominal wall. Laboratory evaluation revealed leucocytosis and lactic acidosis. A new surgical exploration revealed a purulent peritonitis with necrotizing fasciitis involving the right lower abdomen, right psoas muscle and right retroperitoneum. On intensive care unit, the patient was managed with intravenous antibiotics and surgical debridement. In the following days, the patient developed extension of the necrosis to the right chest wall. A computed tomography scan of the chest showed right-sided pleural effusion with erosive aspect of the ribs. Necrotic tissues were debrided and antibiotic was changed due to wound superinfection with Acinetobacter Baumannii.
Discussion:
Necrotizing fasciitis of chest due to acute appendicitis is extremely unusual. The optimal treatment associates appropriate antibiotics, oxygenation of infected tissue, and surgical debridement.
Conclusion:
Acute appendicitis resulting in necrotizing fasciitis of chest is rare but life-threatening. Early diagnosis and treatment is essential to reduce morbidity and mortality.
Insights
Necrotizing fasciitis of the chest wall is a rare complication of acute appendicitis. This case highlights the importance of prompt diagnosis and aggressive treatment, including antibiotics and surgical debridement, for this life-threatening condition.
Area of Science:
- Infectious Diseases
- Surgical Pathology
Background:
- Necrotizing fasciitis is a severe, rapidly progressing soft tissue infection.
- Concurrent necrotizing fasciitis of the chest wall and acute appendicitis is exceptionally rare.
- Prompt recognition and intervention are critical for patient outcomes.
Purpose of the Study:
- To report an extremely unusual case of necrotizing fasciitis of the chest wall secondary to acute appendicitis.
- To emphasize the diagnostic and therapeutic challenges associated with this rare clinical presentation.
Main Methods:
- A case report of a 27-year-old male patient presenting with septic shock post-appendectomy.
- Clinical presentation included abdominal wall erythema, progressing to chest wall necrosis and pleural effusion.
- Management involved intensive care, broad-spectrum antibiotics, surgical debridement, and wound management.
Main Results:
- The patient developed extensive necrotizing fasciitis involving the abdominal wall, retroperitoneum, and chest wall.
- Computed tomography revealed pleural effusion and rib erosion.
- Superinfection with Acinetobacter Baumannii necessitated antibiotic modification.
Conclusions:
- Acute appendicitis can lead to severe, life-threatening necrotizing fasciitis extending to the chest wall.
- Optimal treatment requires a multimodal approach: appropriate antibiotics, adequate oxygenation, and aggressive surgical debridement.
- Early diagnosis and management are paramount to reduce morbidity and mortality.
