GATA3 Expression in Solid Vimentin-Negative Eosinophilic Renal Epithelial Tumors-A Comprehensive Study of 48 Tumors.

Vimentin-negative solid eosinophilic renal tumors, such as renal oncocytoma, chromophobe renal cell carcinoma (chromophobe RCC), low-grade oncocytic tumor (LOT) of the kidney, and eosinophilic vacuolated tumor (EVT), often present diagnostic challenge to pathologists as they can have significant morphologic overlap. Recent studies have shown that the LOT is consistently positive for GATA3. To test the utility of GATA3 in this potentially challenging diagnostic setting, we investigated GATA3 expression in 48 vimentin-negative solid eosinophilic renal tumors with unequivocal diagnosis, which included 19 LOTs, 3 EVTs, 12 chromophobe RCCs, 11 renal oncocytomas (ROs), and 3 -mutated renal tumors.

Challenges and Opportunities in Using Twitter as a Pedagogical Tool in Pathology and Laboratory Medicine Education.

Objectives: Even though the benefits of using Twitter for teaching and information exchange within the pathology community are primarily undisputed, a fair number of users refrain from sharing educational content on this social media platform. The survey aims to identify challenges in using Twitter as a pedagogical tool and discuss ways of converting those challenges into opportunities.

Methods: We performed a cross-sectional survey-based study involving 174 participants from the pathology community on Twitter.
