Another study conducted by Gill et al17 show pleomorphic adenoma as the commonest tumor 61.74% followed by warthin tumor 4.49%, hemangioma 2.11%, monomorphic adenoma 0.53% and myoepithelioma 0.26%, whereas the commonest malignant tumor was mucoepidermoid carcinoma 15.30% followed by adenoid cystic carcinoma 5.28%, carcinoma exploemorphic adenoma 1.32%, acinic cell carcinoma 1.00% and salivary duct carcinoma as 0.53%.
In this article, we describe our study of local data to determine the risk of adopting a conservative approach to a Warthin tumor.
(26,28,32) Tumors that only rarely expressed c-KIT include pleomorphic adenoma, sebaceous carcinoma, mucoepidermoid carcinoma, acinic cell carcinoma, basal cell carcinoma, oncocytoma, and Warthin tumor. (26) The expression of c-KIT in polymorphous low-grade adenocarcinoma is controversial.
Although there are some geographic variations in the prevalence of Warthin tumor worldwide, (2,31,32) the authors of larger series have reported a range of 4 to 13% of all salivary gland tumors.
Warthin tumor (WT) is a well-defined benign salivary gland tumor, most commonly found in the parotid gland.
Papillary cystadenoma lymphomatosum (Warthin tumor, adenolymphoma) is a benign salivary gland tumor that occurs almost exclusively in the parotid gland.
(80) An interesting debate has been ongoing in the literature about the presence of this translocation in Warthin tumor. Some studies have demonstrated its presence in Warthin tumor, whereas others have not found this association.
Which of the following statements regarding papillary cystadenoma lymphomatosum (Warthin tumor) is false, based on this month's Pathology Clinic by Rizzi and Thompson?
(4) This immunophenotype separates OEMCa and ApEMCa from other bilayered oncocytic lesions, namely Warthin tumor and oncocytic cystadenoma/cystadenocarcinomas, where the outer cell layers are only typically p63 positive, that is, basal.
This pattern is often associated with Warthin tumor; however, other benign and malignant entities fall under this diagnostic group.
Sixteen pathologists (6%) submitted a false neoplastic diagnosis (adenoid cystic carcinoma, 1; squamous cell carcinoma, 2; acinic cell carcinoma, 4; Warthin tumor, 1; monomorphic adenoma, 3; benign neoplasm NOS, 5).
