A Salivary Clear Cell Tumor With an Unclear Diagnosis: A Report of a Rare Case

The histopathological diagnosis of salivary tumors is considered complex, due to their histological, phenotypic, and genotypic diversity. There are numerous tumors with morphological and/or immunohistochemical aspects that are superimposable but require very different treatment. In this context, salivary lesions containing clear cells are numerous and form part of the diagnostic challenges. We present the case of a 63-year-old woman with a tumor of the accessory salivary glands of the palate, with a predominant clear cell contingent. The aim of this paper is to report a case of a clear cell salivary tumor and to detail the difficulties of differential diagnosis, highlighting new data in the literature and the role of molecular biology.
