We present a 42-year-old male with botryomycosis initially presenting with left-sided proptosis due to an infraorbital mass. A biopsy through an anterior orbitotomy yielded indeterminate histopathology. The patient later developed a similar oral lesion which was biopsied and found to be botryomycosis. The oral lesion recurred after initial surgical treatment, but responded to antibiotic therapy. Discussion of this case along with a review of the literature is presented to offer guidelines for recognition and managment of this rare disorder.
