Slow-growing gingival mass.
OBJECTIVE
A 33-year-old woman presented with a slow growing palatal gingival mass. The clinical differential diagnosis included benign tumors and tumor-like lesions, including the pyogenic granuloma, peripheral giant cell granuloma, peripheral ossifying fibroma, giant cell fibroma, peripheral odontogenic tumors, and oral focal mucinosis.


METHODS
The lesion was excised and histopathological examination followed by immunohistochemical staining was carried out.


RESULTS
The microscopic findings and the immunohistochemical reactivity was diagnostic for a nerve sheath myxoma.


CONCLUSIONS
The clinical features, microscopic findings, immunohistochemistry, and the differential diagnosis including the relationship to the neurothekeoma are discussed.
