A provisional diagnosis of malignant ulcer was given, and the differential diagnosis with necrotizing sialometaplasia was considered. The occlusal radiograph depicted normal bone architecture., Laboratory investigations were within normal limits. The patient was subjected to incisional biopsy using infiltration anesthesia. The histopathological examination revealed Fibrinoid necrosis with sheet of neutrophils (figure 2) and Few acini surrounded by dense neutrophilic infiltration are present in the left upper corner, Hyperplastic squamous epithelial lining present on the right lower corner (figure 3).
