Oral ulcer by Sphingomonas paucimobilis: first report

Int J Oral Maxillofac Surg. 2016 Oct;45(10):1280-2. doi: 10.1016/j.ijom.2016.07.006. Epub 2016 Aug 8.


The first case of an oral infection caused by Sphingomonas paucimobilis is reported. A 73-year-old man presented with a gingival ulcer with bone exposure affecting the attached gingiva in the anterior maxillary region. He reported pain during chewing and the presence of fever. Since the first case of S. paucimobilis infection was reported in 1977, involving a leg ulcer, the number of reports related to this organism has been increasing, indicating that the bacterium should be considered an emerging pathogen. It is possible that other non-classical pathogens of the oral cavity may be responsible for infectious lesions, which represents a diagnostic and therapeutic challenge.

Keywords: Sphingomonas paucimobilis; chronic obstructive pulmonary disease; oral ulcer.
