Main differential diagnoses:
In case of significant inflammation:
- Take at least one high magnification look to confirm that it is mixed and that lymphocytes are not atypical (otherwise, consult hematopathology, particularly whether it could be a lymphoma, notably extranodal NK/T cell lymphoma, nasal type.
- (Classify as acute (with neutrophils) versus chronic (lymphocytes, eosinophils and/or plasma cells). Also look at any bone fragments for osteomyelitis.) Further information: Osteomyelitis
Benign respiratory mucosa with chronic inflammation.
Bone without significant histopathologic changes.
