Slow-growing gingival mass

Abstract

Objectives: 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.

Study design: 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.
