A Case of Buccal Nodular Fasciitis That Was Difficult to Diagnose

Abstract

A case of locally invasive nodular fasciitis causing trismus and pain due to rapid growth of lesions after low-level laser treatment at another dental office is presented. The lesion was locally controlled by marginal resection and had no recurrence for 4 years after surgery. Histopathologically, the lesion could not be diagnosed by cytology and biopsy. The final pathological diagnosis after surgical resection was nodular fasciitis. The stump after excision was positive, but no recurrence was observed after surgery. The use of low-level laser therapy requires careful consideration of its indications.
