Skin-R1: Clinical Knowledge-Guided Dermatological Diagnosis Using Vision-Language Models

arXiv:2511.14900v2 Announce Type: replace-cross Abstract: Vision--language models (VLMs) have recently shown promise for assisting clinical reasoning in dermatological diagnosis. However, their trustworthiness and clinical utility remain limited by three key challenges: heterogeneous datasets with inconsistent diagnostic labels and concept annotations, the lack of grounded diagnostic rationales for reliable reasoning supervision, and limited scalability when transferring knowledge from small, densely annotated datasets to large collections with sparse labels. To address these challenges, we pr

Why this matters
Why now

The proliferation of advanced vision-language models (VLMs) and increasing investment in AI for healthcare creates a timely convergence for addressing specific challenges in medical diagnosis.

Why it’s important

This development represents a significant step towards more reliable and scalable AI assistance in clinical settings, potentially improving diagnostic accuracy and access in specialized medical fields.

What changes

The explicit focus on guided diagnostic rationales and overcoming data inconsistencies shifts AI from simple pattern recognition to more trustworthy and explainable clinical decision support.
