Abstract—The integration of Convolutional Neural Networks (CNNs) into histopathology promises to revolutionize diagnostics, yet their vulnerability to adversarial attacks poses a significant risk to clinical deployment. This study investigates the relationship between CNN architecture, performance, and adversarial robustness. We benchmarked five distinct architectures (VGG16, ResNet-50, MobileNetV3-Large, EfficientNet-B4, and ConvNeXt-Tiny) on the PathMNIST dataset for classification accuracy, efficiency, and robustness against both Projected Gradient Descent (PGD) and Fast Gradient Sign Method (FGSM) attacks. Our results, averaged over five runs, show that while ConvNeXt-Tiny achieved the highest clean accuracy (93.07%±0.88%), its performance collapsed under low-strength attacks. Adversarial training significantly enhanced resilience, maintaining 62.14%±0.65% accuracy under a PGD attack that reduced the standard model's accuracy to nearly zero. This highlights a critical trade-off between standard accuracy and adversarial robustness, underscoring the need to evaluate models for both safety and reliability before clinical adoption.
