Immunohistochemical diagnosis of necrotizing sialometaplasia
The article presents a clinical case of an immunohistochemical study of a rare disease: necrotizing sialometaplasia in the hard palate. Due to the complexity of the differential diagnosis between necrotizing sialometaplasia and squamous cell carcinoma, an immunohistochemical method was used with antibodies to proteins Ki-67, P53, P63 and cytokeratins-7 and Immunohistochemical study established low proliferative activity of glandular cells in excretory ducts and metaplastic squamous epithelium for Ki-67 protein, significant expression of protein P63 was detected both in the ductal epithelium nuclei and in metaplastic areas and expression of the mutant protein P53 was approximately absent. Marked expression of cytokeratin-7 in the ducts cells and weak expression in necrotic acini of the glands and metaplastic epithelium was noted. It was shown that cytokeratin-15 homogeneously stains the peripheral zone of metaplastic epithelium, which is characteristic of a benign lesion. Thus, the panel of antibodies to proteins Ki-67, P53 and cytokeratins-7 and 15 allows to verify necrotizing sialometaplasia.
