Background: Warthin's tumor is a common benign neoplasm of the salivary gland. Human Herpes Virus 8 (HHV-8) is the etiologic agent for all forms of Kaposi's sarcoma (KS), and HHV-8 DNA is present in saliva, suggesting that non-sexual transmission is associated with latent infection of the salivary gland.
Objectives: To provide insights into the HHV-8 cell tropism, the presence of HHV-8 was investigated in a series of Warthin's tumors of the salivary gland and corresponding adjacent normal tissue.
Study Design: Forty-three patients with Warthin's tumors (cystadenolymphoma) were tested for the presence of HHV-8 DNA, and corresponding adjacent normal tissue samples were obtained from 15 patients. DNA was extracted from the paraffin-embedded tissues. A nested polymerase chain reaction (PCR) assay was applied, and the positive samples were confirmed by direct sequencing.
Results: HHV-8 DNA was detected in 19 out of 43 (44%) salivary gland tumor samples. Among the 15 cases with paired samples, 9 were HHV-8-positive for both samples, 4 were HHV-8-negative for both samples while in two cases HHV-8 was detected only in the tumor specimens.
Conclusions: HHV-8 is frequently detected in adenoid salivary neoplasms, suggesting a significant role of the virus in the etiopathogenesis of the disease. Larger studies are required to investigate the role of HHV-8 in the development or progression of Warthin's tumors.

Background: Different parotid tumors differ in terms of treatment strategies due to their distinct biological behaviors. Time-dependent diffusion magnetic resonance imaging (t-dMRI) can characterize and quantify the cytological indexes, and then aid the differential diagnosis of various tumors. However, the value of t-dMRI in the analysis of parotid gland tumors remains unclear.

Background: The rising incidence of parotid gland tumors, with a focus on pleomorphic adenomas (PMA) and Warthin tumors (WT), necessitates accurate preoperative distinction due to their treatment variability and PMA's malignant potential. Traditional imaging, while valuable, has limited accuracy. This study employs multi-slice computed tomography (MSCT) radiomics coupled with serum alpha-L-fucosidase (AFU) levels to develop a diagnostic model aimed at elevating clinical discernment and precision therapy delivery.

Imaging of parotid tumors is crucial for surgery planning, but it cannot distinguish malignant from benign lesions with absolute reliability. The aim of the study was to establish a diagnostic MRI algorithm to differentiate parotid tumors. A retrospective study was conducted including all patients with parotid tumors, who underwent 3T-MRI and surgery.

This study explores the role of irisin and interleukins in parotid tumors by determining the tissue staining intensity of irisin, the salivary and plasma levels of irisin, and the plasma levels of IL-4, IL-6, IL-10 and TNF-alpha in individuals with parotid tumors. Forty-eight patients and forty healthy individuals were included to the study and allocated into four group. Benign Group I (pleomorphic adenoma), Group II (Warthin's tumor), Group III (mucoepidermoid carcinoma) and Group IV (benign parotid control group, healthy control group).

: A Warthin tumor is a benign salivary gland neoplasm, mostly found in the parotid gland. The number of reported Warthin tumors has increased over the years due to better diagnostic modalities and health system modernization. Warthin tumor rarely transforms into a malignant tumor; in this work, we present all cases reported in the English literature of different types of lymphomas within Warthin tumors.
