Cultured Epidermal Autograft for Total Scalp Reconstruction in a Neonate Following Necrotizing Fasciitis.

Abstract

Necrotizing fasciitis in the pediatric population is a particularly difficult diagnostic and management challenge. Options for soft tissue reconstruction of wounds following surgical debridement have been historically limited, yet recent advancements in bioengineered tissue and matrices have introduced alternative methods of treatment for these patients. We present a case of neonatal necrotizing fasciitis of the scalp requiring full-thickness surgical debridement, which was successfully reconstructed using Epicel cultured epidermal autograft (CEA). A 4-day-old female neonate (gestational age 40 weeks) presented with scalp erythema, blistering, and sepsis following peripartum fetal scalp electrode monitoring. She underwent surgical excision of the scalp to healthy bleeding tissue resulting in a defect of approximately 97% of the scalp, measuring 18 × 19 cm including 4 × 3.5 cm of exposed bone at the occiput. Initial provisional coverage of the defect was obtained with Integra collagen matrix bilayer dressing to stimulate granulation over exposed bone. Concurrently, a 2 × 4-cm excisional biopsy of the left groin skin was obtained for CEA in vitro expansion over 21 days. Then, autograft sheets were applied to achieve total scalp coverage. Clinical assessments at 1 week, 1 month, and 2 months postoperatively exhibited, approximately, 60% take, 80% take, and 90% take, respectively. Scalp involvement in neonatal necrotizing infections is a notably rare presentation as surmised by our review of the literature, and to our knowledge, this is the first report on the use of Integra and CEA for near-total neonatal scalp coverage.
