Lymphoid lesions of salivary glands : malignant and Benign
2007
Lesions of salivary glands with a prominent lymphoid component are a heterogeneous group of diseases that include benign reactive lesions and malignant neoplasms. Occasionally, these pathologic entities present difficulties in the clinical and pathological diagnosis and prognosis. Lymphoepithelial sialadenitis, HIV-associated salivary gland disease, chronic sclerosing sialadenitis, Warthin tumor, and extranodal marginal zone B-cell lymphoma are examples of this pathology that are sometimes problematic to differentiate from one another. In this paper the author reviewed the main clinical, pathological and prognostic features of these lesions.
Tissue microarray construction for salivary gland tumors study
2012
Objective: To describe and discuss the design, building and usefulness of tissue microarray (TMA) blocks for the study of salivary gland tumors (SGTs). Study Design: Two hundred thirty-eight formalin-fixed, paraffin-embedded SGTs were arranged in blocks of TMA using a manual tissue arrayer. Three representative cores of 1.0, 2.0 or 3.0mm were taken from each original block and their characteristics were analyzed and described. Results: It was created 12 TMA blocks that presented highly representative neoplastic cylinders. However, those neoplasias rich in cystic spaces such as mucoepidermoid carcinoma and Warthin tumor presented more difficulties to be sampled, as the neoplastic tissue avai…
Synchronic nasopharyngeal and intraparotid warthin tumors: a case report and literature review
2014
Warthin tumor is the second most frequent benign salivary gland tumor after pleomorphic adenoma; it occurs almost exclusively in the parotid gland and peri-parotideal lymph nodes, although it may rarely present in other locations. It may be multicentric and bilateral in a small percentage of cases. Nasopharyngeal Warthin tumor is very rare, and the presence of a synchronic WT involving nasopharynx and parotid is an exceptional event, as it has been described only twice in the literature. In this article we report an additional case of a synchronic Warthin tumor and review the related literature. Key words:Warthin tumor, synchronic WT, multicéntrico, nasopharynx.
