AbstractActinomycosis is a relatively rare infection caused by saprophytic bacteria of the oral cavity and gastrointestinal tract that can become pathogenic. The chronic hyperglycemia of diabetes mellitus induces events that promote structural changes in various tissues and are associated with problems in wound healing. This infection remains largely unknown to most clinicians because of its different presentations, and palatal involvement is extremely rare. This report describes the case of a 46-year-old woman who was diagnosed with actinomycosis involving the hard palate. The main clinical, histopathologic, and therapeutic characteristics and differential diagnosis of actinomycosis are reviewed. To date, 3 cases of actinomycosis involving the hard palate have been reported. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.
