Objective: Carcinoma ex-pleomorphic adenoma (CEXPA) represents a malignant transformation from a recurrent or primary pleomorphic adenoma (PA), and the immune response may be essential in this process. Therefore, in this study, we aimed to identify and quantify subpopulations of dendritic cells (DCs) in CEXPA, residual PA in CEXPA (rPA), and PA.
Materials And Methods: A multicenter study was performed collecting salivary gland tumor (SGT) samples from three Oral and Maxillofacial Pathology Centers.
A solitary fibrous tumor (SFT) is an uncommon mesenchymal tumor characterized by spindle cell proliferation that rarely affects the oral cavity. The clinical and histopathologic features of an oral SFT are described for the benefit of dental practitioners who may encounter one of these rare cases. A 25-year-old man presented with a slow-growing swelling in the left buccal mucosa.

Objective: To identify and quantify DCs in tonsillar squamous cell carcinoma (TSCC) under the influence of HPV infection.
Methodology: CD1a and CD83 antibodies were used to identify immature dendritic cells and mature dendritic cells by immunohistochemistry in 33 primary TSCC and 10 normal tonsils (NTs), respectively.
