Nasal septal abscess is a rare otorhinolaryngologic condition characterized by a collection of pus in the space between the cartilaginous or bony nasal septum and its overlying mucoperichondrium or mucoperiosteum. The majority of the nasal septal abscesses develop secondary to an infected septal hematoma, which most commonly occurs following nasal trauma. Other than septal hematoma, spreading of the microorganism from the infected sinonasal mucosa could result in an nasal septal abscess. Aerobic bacteria are the most common organisms isolated from nasal septal abscesses. Less commonly, anaerobic bacteria and fungi are isolated from nasal septal abscesses. To date, there have been no reports showing that the protozoans were isolated from a nasal septal abscess. This paper presents a case study of an adolescent male diagnosed with Entamoeba histolytica-isolated nasal septal abscess.
