Cervical necrotizing fasciitis affects only immunocompromized patients? Diagnostic challenges, treatment outcomes and clinical management of eleven immunocompetent adult patients with a still fatal disease.

Cervical Necrotizing fasciitis (CNF) has been reported as an unusual rapidly progressive, life-threatening, inflammatory disease that is known to affect predominately immunocompromised patients. Few case reports have been sporadically published involving immunocompetent adults. This is the first study presents a series of immunocompetent CNF patients. A retrospective chart review study was performed on immunocompetent adults with CNF from January 2003 to December 2019. The diagnosis was histologically confirmed. We analyzed epidemiological, clinical, laboratory and imaging findings and discussed them along with the treatment plan. A total of eleven adult patients were included in the study. The average age was 43 years, ranging from 17 to 62 years. The average hospitalization time was 28 days, ranging from 10 to 129 days. All patients presented with cervical erythema and odynophagia. The causative factors are known in nine patients. Tissue cultures demonstrated mixed flora in six patients. Seven underwent a temporary tracheostomy. Wide neck exploration incisions were performed in all patients as the diagnosis was established after imaging findings. In nine cases the anterior-upper mediastinum was affected but only in two patients extension of the surgical planes to the mediastinum was performed. Four patients developed polyserositis. Nine patients survived and two developed multiorgan failure and died. There seem to be no differences between immunocompetent and immunocompromised CNF patients, in regards to clinical, imaging and laboratory findings as well as their treatment plan.
