The PAR dataset: Prostate biopsy whole slide images from an underrepresented Middle Eastern population.

Publicly available histopathology datasets remain scarce, and those that do exist predominantly represent Western populations.

Consequently, the generalizability of artificial intelligence models to populations from less digitized regions, such as the Middle East, is largely unknown.

This motivates the public release of our dataset to support the development and validation of pathology artificial intelligence models across globally diverse populations.

Each glass slide was scanned by three different whole-slide scanners.
