Article Abstract
In the present work, 20 patients with salivary pleomorphic adenoma were recruited for FTIR spectroscopic measurement. These obtained FTIR spectra were analyzed and compared. It was found that there were significant differences in the spectral features of the skin covering normal salivary gland, pleomorphic adenoma, and carcinoma change of pleomorphic adenoma, such as the changes in peak position, band shape and relative intensity of the bands in the ranges of 1000-1800 cm(-1) and 2800-3000 cm(-1). Pathological diagnosis demonstrated that 2 of the 20 patients suffered actually carcinoma change of pleomorphic adenoma, which is in good agreement with the result of FTIR spectroscopicmeasurement. FTIR spectroscopic m ethodsuggested that pleomorphic adenoma is the intermediate between normal salivary gland and carcinoma change of pleomorphic adenoma.

Myoepithelial carcinoma (MECA) is a malignant neoplasm composed exclusively of myoepithelial cells and accounts for less than 1% of all salivary gland tumors. Its diagnosis is often challenging due to histologic overlaps with benign lesions and its variable morphologic presentation. Although molecular profiling has emerged as a valuable tool in salivary gland tumor classification, the genetic landscape of MECA remains incompletely defined.

Salivary gland carcinosarcoma is a combination of malignant epithelial and sarcomatous tumors and can develop from a preexisting pleomorphic adenoma or de novo. These tumors are rapidly growing infiltrative tumors and have an extremely poor prognosis, with a high frequency of lymphatic and hematogenous spread at the time of diagnosis. Approximately half of the cases of carcinosarcoma arise from preexisting pleomorphic adenoma with a long-standing clinical history of parotid mass.
