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.

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.
