Necrotizing sialometaplasia is a benign, reactive, and
self-limiting inflammatory disorder with clinical and histologic
features resembling carcinoma. A fifty-eight-yearold
woman presented with a firm submucosal mass on
the right side of the upper lip, measuring 0.5 cm.
Histopathologic examination of the incisional biopsy
specimen was reported as adenoid cystic carcinoma,
resulting in removal of the mass with a large excision and
reconstruction of the primary site. However, final
histopathologic diagnosis of the excised mass was
necrotizing sialometaplasia. No recurrences occurred
during a three-year follow-up. This report draws attention
to the difficulty in distinguishing between necrotizing
sialometaplasia and adenoid cystic carcinoma.
