Abstract :
This report describes a rare case of nodular fasciitis (NF) of the oral cavity, discussing the clinical, histological, and
immunohistochemical characteristics. Histopathologic diagnosis of this type of lesion can be challenging due to its differential
diagnosis, which principally includes sarcoma. The patient presented with a painless, well-defined nodule, reported as increasing in
size, located at the apical aspect of the upper left buccal sulcus. Histologically, the lesion revealed spindle cell proliferation arranged
in fascicles, while immunohistochemistry demonstrated positivity for smooth muscle actin. Eight months after complete surgical
excision, no signs of local recurrence have been observed.
