We report a case of acute unilateral maxillary sinusitis, caused by Bacillus licheniformis, in a 35-year-old French soldier stationed in Djibouti. It was easily identifiable due to its typical culture and resistance profile. This case is interesting for two reasons: first, it is, to our knowledge, the first case of sinusitis attributed to this microbe, and second, it has rarely been described in immunocompetent patients without altered skin or mucous membranes.
