Necrotizing Sialometaplasia (NS) is a rare, benign, self-limited, inflammatory and necrotizing reaction of the salivary glandular tissue. Due to the clinical picture (a painful ulcer with well-defined edges), and histopathological characteristics (nuclear and cellular pleomorphism of ductal cells) NS can mimic a malignant lesion. The correct diagnosis is important because NS shows a spontaneous resolution and therefore no further treatment is needed. We report a very unusual case of spontaneous and recurrent NS located on the anterior tonsillar pillar in a 43-year old man, which clinically mimics a malignant lesion. The clinician should be aware to include NS in the differential diagnosis of ulcers in soft palate and tonsillar pillars.

坏死性涎腺化生（NS）是一种罕见的、良性的、自限性的涎腺组织炎症性坏死反应。由于临床表现（边缘清晰的疼痛性溃疡）以及组织病理学特征（导管细胞核及细胞多形性），NS可酷似恶性病变。正确诊断很重要，因为NS可自行消退，因此无需进一步治疗。我们报告一例非常罕见的病例，一名43岁男性的扁桃体前柱出现自发性复发性NS，临床上酷似恶性病变。临床医生应注意将NS纳入软腭和扁桃体柱溃疡的鉴别诊断中。小涎腺、坏死性涎腺化生、口腔溃疡、鳞状细胞癌、扁桃体柱
