Secondary craniofacial necrotizing fasciitis from a distant septic emboli: A case report

BACKGROUND

Craniofacial necrotizing fasciitis (CNF) is an uncommon but fatal infection that can spread rapidly through the subfascial planes in the head and neck region. Symptoms usually progress rapidly, and early management is necessary to optimize outcomes.

CASE SUMMARY

A 43-year-old man visited our hospital with left hemifacial swelling involving the buccal and submandibular areas. The patient had fever for approximately 10 d before visiting the hospital, but did not report any other systemic symptoms. Computed tomography scan demonstrated an abscess with gas formation. After surgical drainage of the facial abscess, the patient’s systemic condition worsened and progressed to septic shock. Further examination revealed pulmonary and renal abscesses. Renal percutaneous catheter drainage was performed at the renal abscess site, which caused improvement of symptoms. The patient showed no evidence of systemic complications during the 4-mo post-operative follow-up period.

CONCLUSION

As the patient did not improve with conventional CNF treatment and symptoms only resolved after controlling the infection, the final diagnosis was secondary CNF with septic emboli. Aggressive surgical decompression is important for CNF management. However, if symptoms worsen despite early diagnosis and management, such as pus drainage and surgical intervention, clinicians should consider the possibility of a secondary abscess from internal organs.

Severe bacterial skin infections

The severe bacterial diseases discussed herein are those that present dermatological lesions as their initial manifestations, for which the dermatologist is often called upon to give an opinion or is even the first to examine the patient. This review focuses on those that evolve with skin necrosis during their natural history, that is, necrotizing fasciitis, Fournier gangrene, and ecthyma gangrenosum. Notice that the more descriptive terminology was adopted; each disease was individualized, rather than being referred by the generic term "necrotizing soft tissue infections". Due to their relevance and increasing frequency, infections by methicillin-resistant Staphylococcus aureus (MRSA) were also included, more specifically abscesses, furuncle, and carbuncle, and their potential etiologies by MRSA. This article focuses on the epidemiology, clinical dermatological manifestations, methods of diagnosis, and treatment of each of the diseases mentioned.

Klebsiella pneumoniae necrotizing fasciitis on the upper lip in a patient with uncontrolled diabetes

A 60-year-old woman with a history of diabetes mellitus and chronic renal failure was admitted to the hospital with severe pain in the upper lip, which began 4 days prior to admission, accompanied by a bullous lesion and suspected cellulitis in the upper lip. Immediately after admission, as the patient´s general condition worsened, tests revealed a non-ST elevated myocardial infarction, septic embolism of the lung, as well as septic shock. Her upper lip suddenly presented a gangrenous and necrotic change, which the tissue and blood culture confirmed to be a Klebsiella pneumoniae infection. After a quick response, the patient’s general condition improved. Subsequently, serial debridement was performed to effectively clear away the purulent discharge. While under general anesthesia, the process confirmed full-layer necrosis of the upper lip including the orbicularis oris muscle. Almost half of the entire upper lip sustained a full-layer skin and soft tissue defect, with scar contracture. Six months later, to correct the drooling and lip sealing following the defects, a scar release and an Abbe flap coverage were performed considering both functional and aesthetic aspects. The follow-up revealed a favorable corrective result of the upper lip drooling, and the patient was satisfied from a functional perspective.
