A diagnostic error of a necrotizing sialometaplasia: Case report.
Annals of Medicine and Surgery 2022 Februrary
INTRODUCTION: Necrotizing sialometaplasia (NSM) is a benign, self-limiting, inflammatory disease of salivary glands, mainly involving the minor salivary glands in the palate. This lesion can mimic a malignant neoplasm, both clinically and histopathologically, manifesting as a submucosal swelling or as an ulcer of the palate. We illustrate our work with a case of necrotizing sialometaplasia misdiagnosed as carcinoma.
CASE PRESENTATION: A 26 years old woman presented to dental treatment and consultation center of Rabat, for a rehabilitation of left palatal bone defect with an obturator prothesis. A postsurgical erythematous area was noted at the left palate during intraoral examination. After medical file study, we founded that she had a necrotizing sialometaplasia treated by maxillectomy of the left maxillary bone, and we realized that a diagnostic error was made leading to an aggressive treatment.
CLINICAL DISCUSSION: Necrotizing sialometaplasia can be misdiagnosed clinically and microscopically as a malignant neoplasm, resulting in inappropriate and aggressive treatment like the case presented.
CONCLUSION: The diagnosis of NSM is challenging, the role of histopathology and immunohistochemistry is of paramount importance.
