Diffuse Large B-Cell Lymphoma Arising in Warthin’s Tumor: Case Study and Review of the Literature
Güliz Özkök,Funda Taşlı,Nazan Özsan,Rafet Öztürk,Hakan Postacı 대한병리학회 2013 Journal of Pathology and Translational Medicine Vol.47 No.6
Warthin’s tumor is the second most common type of salivary gland tumor. Microscopically, Warthin’s tumor displays a proliferative epithelial component and lymphoid stroma. Carcinomas arising from the epithelial component are well known, but malignant transformations of the lymphoid stroma are rare. When they do occur, they are most commonly B-cell type non-Hodgkin lymphomas. A 60-year-old male patient underwent surgical resection of a parotid mass. After superficial parotidectomy, microscopic examination indicated that the tumor was of epithelial components with basaloid and oncocytic columns of cells neighboring lymphoid components. In addition to the lymphoid follicles with distinct germinal centers, there were large, bizarre and extremely atypical neoplastic cells seen in the lymphoid component. Large neoplastic cells were diffusely CD20 and CD30 positive. The patient was diagnosed with “Warthin’s tumor and diffuse large B-cell lymphoma with expression of CD30.” The histopathologic and clinical features are discussed along with a review of the literature.

A Different Perspective on Macroscopic Sampling of Cholecystectomy Specimens
Asuman Argon,Ayşe Yağcı,Funda Taşlı,Tulu Kebat,Senem Deniz,Nazif Erkan,Gül Kitapçıoğlu,Enver Vardar 대한병리학회 2013 Journal of Pathology and Translational Medicine Vol.47 No.6
Background: Because there may be interdepartmental differences in macroscopic sampling of cholecystectomy specimens, we aimed to investigate differences between the longitudinal sampling technique and our classical sampling technique in cholecystectomy specimens in which there was no obvious malignancy. Methods: Six hundred eight cholecystectomy specimens that were collected between 2011 and 2012 were included in this study. The first group included 273 specimens for which one sample was taken from each of the fundus, body, and neck regions (our classical technique). The second group included 335 specimens for which samples taken from the neck region and lengthwise from the fundus toward the neck were placed together in one cassette (longitudinal sampling). The Pearson chi-square, Fisher exact, and ANOVA tests were used and differences were considered significant at p<.05. Results: In the statistical analysis, although gallbladders in the first group were bigger, the average length of the samples taken in the second group was greater. Inflammatory cells, pyloric metaplasia, intestinal metaplasia, low grade dysplasia, and invasive carcinoma were seen more often in the second group. Conclusions: In our study, the use of a longitudinal sampling technique enabled us to examine a longer mucosa and to detect more mucosal lesions than did our classical technique. Thus, longitudinal sampling can be an effective technique in detecting preinvasive lesions.
