Recurrent neonatal suppurative submandibular sialadenitis: a case report. Case report: We describe a case of a premature infant born at 28 1/7 weeks of gestation who, 12 days after birth, developed a submandibular inflammatory mass with exudation of pus into the oral cavity. The growth of Staphylococcus aureus in the culture confirmed a diagnosis of submandibular sialadenitis. The symptoms rapidly improved under antibiotic therapy. The infection recurred on day 25, also with exudation of pus into the oral cavity. This time the culture showed the growth of Enterococcus faecalis. The symptoms resolved in response to antibiotic therapy. Review of the literature: To date, 25 newborns with suppurative submandibular sialadenitis have been reported in the English language literature. To our knowledge, this is the first description of a recurrence.
Conclusion: Although neonatal suppurative submandibular sialadenitis is rare, this case report and literature review highlight the importance of prompt diagnosis and treatment.
