Nodular Fasciitis of the Oral Cavity with Partial Spontaneous Regression (Nodular Fasciitis)

摘要: Nodular fasciitis is a lesion found in the subcutaneous fascia that micoscopically presents as benign proliferation of fibroblasts and myofibroblasts, which may be mistaken for sarcoma due to clinically rapid growth. Diagnosis by histopathology immunohistochemical profile. We describe case nodular oral cavity demonstrated partial spontaneous regression. The patient was 32-year-old man with buccal mucosal mass, had grown rapidly 45 days. On microscopic examination, displayed well-delineated but not encapsulated spindle cells, growth pattern. Immunohistochemical analysis showed positivity cells antibodies against smooth muscle actin muscle-specific (HHF-35). Treatment such lesions typically involves complete conservative excision, regress eventually absence definitive treatment.
