A case report of Actinomyces-associated vulvar necrotizing soft tissue infection: Aspects of multidisciplinary care.

Abstract

Introduction and importanceNecrotizing soft-tissue infections are life-threatening infections with significant morbidity and mortality.Case presentationA 36-year-old female gravida 1 para 1001 with a history of intravenous drug use and homelessness presented to the emergency department for a three-day history of labial pain, swelling, and fevers. A contrast tomography scan revealed necrotizing soft tissue infection of the mons and vulva with subcutaneous gas. Empiric broad-spectrum antibiotics were initiated. She underwent an emergent two-staged surgical debridement and delayed primary closure after 1-month in the hospital. She was discharged to complete a 9 to 12 month course of antibiotics. Multidisciplinary team was central to patient care.Clinical discussionNecrotizing soft tissue infections are a diverse group of infections affecting the subcutaneous tissue, muscle, and fascia. Actinomyces is a rare cause and require long-term antibiotics. Early recognition and emergent surgical debridement has been shown to reduce morbidity and mortality. A multidisciplinary approach is critical for proper wound care and healing, pain management, and long-term follow up.ConclusionsActinomyces-associated vulvar NSTIs are life-threatening infections requiring early surgical debridement, long-term antibiotics, and multidisciplinary approach.
