Background: Paronychia is defined as infection afflicting the eponychial nail folds of the hand or foot. Such infections are rarely reported in the perinatal age group, and not previously described in a neonate younger than 2 weeks. Trauma resulting in inoculation of the nail fold is the most common predisposing factor to paronychia. Oral trauma in the pediatric population from finger sucking predisposes this population to a different set of bacterial pathogens than adults. Contamination can progress to infection and abscess formation within the nail fold with the most prevalent vector in adult infections being Staphylococcus aureus. Comparatively, mixed anaerobic and aerobic infections tend to afflict children with oral soothing habits. Methods: This is a case report will present the rare occurrence of a paronychia in a neonate caused by methicillin-resistant Staphylococcus aureus. Results: The management and treatment strategies for paronychia in this atypical neonatal patient consisted of incision and drainage and antibiotic therapy. Conclusion: Neonates with oral self-soothing behaviors may be more at risk for developing paronychia of mixed anaerobic and aerobic infections. Initial therapy with broad-spectrum antibiotics amoxicillin/clavulanate or clindamycin is suggested. Incision and drainage in the perinatal setting coupled with antibiotics is curative.
