The authors describe necrotizing sialometaplasia, a benign inflammatory lesion primarily involving the minor salivary glands of the hard palate. The lesion presents itself as a deep-seated palatal ulcer with clinical and histologic features mimicking those of a malignant neoplasm. The lesion is believed to be the result of vascular ischemia initiated by trauma. An incisional biopsy is required to confirm the diagnosis, and the lesion heals by secondary intention within four to 10 weeks.
作者描述了坏死性涎腺化生，这是一种主要累及硬腭小涎腺的良性炎性病变。该病变表现为深部腭部溃疡，其临床和组织学特征类似于恶性肿瘤。据信该病变是由创伤引发的血管缺血所致。需要进行切开活检以确诊，且病变会在4至10周内通过二期愈合。
